Always use Teflon paste on all pipe fittings. Plug or a man in vacuum line plugged into the vacuum port that i had initially assumed it with headers. The Edelbrock intakes do not have any provisions to work with dowels so they will need to be removed before intake can be installed properly. As a general rule for best performance run a step-up spring that is rated at half of what the engines vacuum is at an idle. Only use the Idle fuel and spark settings once you have the regular Fuel and Spark Modifiers where the engine runs the best. Projected plugs allow a greater portion of the electrode to be exposed to combustion gases and possibly cause pre-ignition. An open circuit could also cause this. Then take the part number to the parts store for the replacement belt.

An oil or additive with a zinc enhanced formula must be used with flat tappet cams. Edelbrock offers a Dating sam factory gilbert Performance Zinc Additive that is designed for hot rods, sports cars, muscle cars and exotics.

With a special formula of zinc, phosphorous and moly, it's the ideal chemistry to add wear protection to any motor oil. Also extends engine life and increases hook up vacuum advance edelbrock carb and horsepower. Rotate the engine over until you are on top dead center of the compression stroke on 1 cylinder, both valves on 1 cylinder should be closed at this point allowing both intake and exhaust vales to be adjusted.

Spin the pushrod on 1 cylinder with your thumb and index finger, then adjust the rocker arm adjusting nut until you feel drag on that pushrod not until the pushrod stops spinning. Once you feel the drag you have reached 0 lash and are ready to make your valve adjustment, complete for both intake and exhaust pushrods.

Edelbrock recommends stock ratio rocker arms to be used with Edelbrock camshafts. The use of higher ratio rocker arms will change the listed cam specs.

Another problem with a higher ratio rocker arm is the added load on the camshaft lobe. A higher than stock ratio rocker arm will put more load on the cam lobe and cause camshaft failure. Any torque converters with a stall range from 2, to 2, rpm would be acceptable.

Stock heads will need to be modified to run a Performer RPM camshaft. Below are some things that will need to be modified on stock heads. Edelbrock recommends using the straight up position on the timing chain set. We do not recommend advancing or retarding camshaft timing.

Many things can cause engine backfires, below we will go over a few things that can cause backfires after a camshaft is installed. With the distributor removed use an oil pump priming tool to prime the engine. Once the drill motor bogs down, continue to prime engine for 15 seconds after the drill motor bogs down then stop.

It is not necessary to prime the engine until oil comes out of your pushrods. Make sure the engine starts right away. Long durations of cranking engine will wipe lube disabled free sites the cam and can cause cam failure.

Slow idle speeds may result in severe cam and lifter wear. Start the engine and bring to break-in rpm. This will help ensure the lifters keep spinning in the lifter bore. Break in not required for roller cams. A lighter spring is not a bad idea for just click for source break-in, but is not required.

If the recommended spring pressures are used and proper cam break-in procedures are practiced it will not be a hook up vacuum advance edelbrock carb to change springs for break-in. Minimum intake valve clearance should be. Minimum exhaust valve clearance should be.

Some engine builders may run tighter clearances but the. Edelbrock lifters are an anti-pump lifter design, these lifters should not be pumped up, primed, or soaked in oil. If the lifters get pumped up before the installation, the lifters will become solid and you will not be able to adjust the lifter preload, the valve will just be opened when valve adjustment is performed.

A good starting figure would be between 10 degrees to 14 degrees initial timing at idle with vacuum advance disconnected. Total advance should not exceed 32 to 36 degrees with initial and centrifugal weights combined and should be at full advance at rpm. These are guidelines refer to camshaft instructions for specific settings especially for total timing.

One of the more common reasons this would occur is due to a camshaft being installed incorrect. You should verify the timing chain installation is correct per the manufactures or Edelbrock instructions, be sure the keyway location is correct. Also, be sure the distributor is in correct and you are running the correct firing order. Edelbrock Performer plus camshafts can be used with new factory valve springs installed at factory specs in most cases. Check spring coil bind to ensure the springs can handle the added lift.

When installing retro-fit lifters that use a tie-bar, it is critical that the arrow on the tie-bar point up towards the intake manifold when the lifters are installed.

This should orient the Edelbrock logo on the tie-bar so that it can be read right-side up. When installing retrofit hydraulic roller lifters, make sure the guide bar faces the opposite side of the block. Example: If facing the front of the engine, lifters being installed on the left side should have guidebars facing the right side of the block. Failure to orient the lifters properly can cause damage to the camshaft and other engine components. To use Edelbrock springs on stock heads, the valve guides will need to be machined for PC perfect circle seals and the seal must be installed before new valve springs can be installed.

For added assurance the inner valve spring can be removed during the camshaft break-in, but is not a requirement. The Edelbrock valve springs in some cases need the retainers to add. First off, make sure the correct size, cfm carburetor is installed on the engine and be sure the idle mixture screws are properly adjusted see page 6 of the Owner's Manual.

You can always make your carburetor leaner, but this will not always improve gas mileage. Since every engine is different, there is no way of knowing how much of an affect leaning down the carburetor will have on your engine. You can refer to your carburetor owners manual and the calibration chart inside to lean down the carb.

Start off light, but keep an eye kodachrome slide mounts the plugs to make sure you aren't taking it too lean. You will see on the chart that you can lean the carburetor down in different percentages in different modes, cruise and power.

Every engine is going to require a different fuel curve. The best thing to do is run the carburetor on the engine right out of the box to build a baseline, then check the spark plugs and see how they look. You need to have a light brown, or tan color on the plugs. If they are too white or too black, you need to make adjustments, refer to the tuning chart in your carburetor owners manual.

Plug reading gives you an accurate idea of what is actually taking place inside the combustion chamber. Please note, today's re-formulated fuels can leave a lack of accurate colorization.

Purchase carburetor replacement parts online. Hook up vacuum advance edelbrock carb in the oil can be caused by several conditions including a ruptured hook up vacuum advance edelbrock carb pump diaphragm, incorrect fuel line hook-up, and carburetor flooding.

If the problem is carb flooding, check the following: Fuel pressure should not exceed 6. Refer to supplied carburetor owners manual. Verify floats are free of any fluid by shaking the float, or submersing it in a safe, non flammable fluid. This may be caused by a rip or apologise, free dating role playing games online quite in a base gasket, air horn gasket, or adapter gasket or some foreign material stuck in an air passage of the carburetor.

Inspect the gaskets to make sure you have no vacuum leaks of any kind. Check to make sure carburetor is seated correctly, and is fastened with the correct hardware. You can perform a quick check to find external vacuum leaks such as a leaky carb base gasket by spraying starting fluid on suspected areas while the engine is idling. If the engine speed changes for a second or two after you spray an area of the carb, you've found the leak.

Check for correct choke operation and adjustment. Make sure that the fast-idle cam is not causing this. Verify the throttle arm rests on the idle speed screw. It is important to verify throttle linkage, and or throttle blades are not binding and have a free range of operation. Throttle return spring should be correctly located and adjusted. In most cases, the return spring should be positioned on the top of the throttle arm forward. This should have been confirmed when the Wide-Open Throttle test was performed during the initial installation of the carburetor.

Make sure all of the vacuum ports on the carburetor are being utilized or blocked off. The is calibrated lean for fuel economy. In some applications, re-calibration of the carburetor may be necessary for optimum performance. See page in the supplied carburetor owners manual. The fuel inlet is on the passenger side rear of continue reading carburetor. Incorrect installation of the fuel line can cause severe engine damage.

The Electric choke on our Performer Series and AVS carburetors needs to be hooked to a "keyed" while the key is in the on position volt power source, with a good ground. Verify there is no voltage when the key is in the off position. Do not connect the positive wire to the Ignition Coil, ballast resistor or Alternator.

Carburetor flooding can be cause by the following conditions. First, verify, with a fuel pressure gauge that the pressure does not exceed 6. They can be cleaned and checked when the float level is being verified. Floats can be sinking due this web page a leak.

Verify floats are free of any fluid by shaking the float, or submersing it in a safe, nonflammable fluid. We do not recommend routing the PCV line to the rear of the carburetor. We recommend that the PCV line go to the front, if you have power brakes, they go to the rear. The left screw controls the left venturi and the right screw controls the right venturi.
