PRO TIPS

1. Deep Clean Every Passage

When you have the carburetor disassembled for this rebuild, don''t just swap the parts and put it back together. Use a dedicated carburetor cleaning solvent and high-pressure compressed air to blow out every internal passage. The tiny idle circuits and the emulsion tube are notorious for collecting varnish and debris that a simple spray-down won''t remove. If you can''t see light through a jet or passage, it isn''t clean yet. Ensuring these internal pathways are crystal clear is the only way to guarantee the new components in this kit can do their job effectively.

2. Inspect the Throttle Shaft for Play

Before installing your fresh gaskets, check the throttle shaft where it passes through the carburetor body. If you can wiggle the shaft up and down or side to side, you have a vacuum leak that no rebuild kit can fix. Worn throttle shaft bushings allow "unmetered air" to enter the engine, making it impossible to achieve a steady idle. If your body is worn out, you may need to have it re-bushed or consider a new carburetor body. However, if the shaft is tight, the base gaskets and O-rings provided in this EMPI kit will provide a perfect seal for optimal tuning.

3. Set the Float Level Correctly

One of the most overlooked steps in a Solex rebuild is verifying the float height. While this kit provides a new needle and seat, you must ensure the float itself is in good condition (no fuel trapped inside it) and that it is adjusted to the factory specification. On a 34PICT-3, a float level that is too high will cause the engine to stumble and run rich, while a level that is too low will cause a lean condition and hesitation. Use the washers provided in the kit to shim the needle and seat assembly to achieve the correct height, ensuring your fuel bowl stays at the perfect level for all driving conditions.
