PRO TIPS FROM THE SHOP

Thoroughly Clean the Internal Passages

When you have the Holley Bugspray disassembled, simply replacing the gaskets isn''t enough. These carburetors are notorious for accumulating varnish in the tiny idle circuits and transition ports. Use a high-quality aerosol carburetor cleaner followed by high-pressure compressed air to blow out every single passage. If you don''t see cleaner spraying out of the exit hole of a circuit, that passage is still blocked. A single microscopic speck of dirt can cause a lean condition that will make your engine run hot or stumble under load, so take the extra time to ensure the casting is surgically clean before installing the new EMPI components.

Check and Set Your Float Level

Installing a new needle and seat often changes the float height, which is the most critical adjustment for fuel mixture control. If the float is set too high, the carburetor will flood or "percolate" fuel into the intake after the engine is shut off; if it is too low, the engine will starve for fuel at high RPMs. Always consult the original Holley specifications for the Bugspray to set the dry float height. Use a dedicated float gauge or a high-quality caliper to ensure the measurement is exact. This small step is the difference between a carburetor that just "runs" and one that provides a crisp, perfect power band.

Inspect the Throttle Shaft for Wear

Before you button everything up with your new gaskets, check the throttle shaft for any side-to-side or up-and-down play. The Holley Bugspray is an older design, and over decades of use, the shaft can wear out the bores in the carburetor body. If there is significant play, you will have a persistent vacuum leak that no amount of rebuilding or tuning can fix. If you find a leak here, you may need to have the body bushed. However, if the shaft is tight, the EMPI gaskets and seals in this kit will provide a perfect airtight seal, allowing you to achieve a rock-steady idle that makes your VW a joy to drive in traffic.
