Re: Throttle Body vs Carb Spacer
Throttle body spacer is for a tbi (throttle body injection)on a newer motor.
Promotes better flow into the intake.
Not applicable for your carbed motor.
A carb spacer is used primarilly to reduce heat to your carb to reduce or eliminate the fuel boiling in the carb. It might help flow if you have a poor flowing intake.
A throttle is part of a carb. It's the primary plate. It controls the amount of fuel vapor that flows into the intake and on into the cylinder to be burned. The fuel is vaporized in the top of the carb.
You want better economy then you need to optimize your timing and possibly adjust the APT (adjustable part throttle) in your carb.
What's your initial timing?
