Good To Know

Q: What are the signs of a leaking carburetor intake boot? A: Common symptoms include a high or hanging idle, popping on deceleration, hard starting, and a lean-running engine.

Q: Can I repair a cracked boot with silicone or glue? A: Temporary patches rarely hold up against engine heat and fuel vapor, so replacing the boot is the only reliable fix.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
