Good To Know

Q: How do I know if my old boots are bad? A: Symptoms include a hanging or high idle, difficulty tuning the carburetors, and visible cracks in the rubber. Spraying starting fluid near them while running can also reveal leaks.

Q: Do these include mounting clamps? A: This set includes the four rubber boot insulators; reuse of your original clamps or acquisition of new clamps may be necessary.

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