Re: Loud air sucking noise on acceleration

Going to start it tomorrow (Saturday) and see what I can find. Will do some water spray and carb cleaner tests.
The connections to the vacuum tubing look pretty solid I really don’t think it’s leaking where a clamp is on the tubing. The PCV valve is a bit cocked, so I may pickup some more vacuum tubing and make that connection more secure.

And, the gasket at the base of the carb is secure and the carb mounting nuts are pretty tight.
