Re: 4 hole carb spacer for better signal, will it work?
So, the "Bog" when you stomp on the gas is not from too MUCH fuel, it's too LITTLE fuel. The accelerator pump and squirter are to fill in the hole left when the large throttle blades open.
Rich and lean are from a jetting perspective, but it can still have a lean backfire when you punch it because of the "hole" in the a/f curve that the pump shot didn't fill even if it is jetted correctly.
A larger squirted or more aggressive pump cam can do wonders.
Ported vacuum source should have ZERO vac at idle. If you aren't at zero something is wrong...
