Air:Fuel Help. Cannot Get it Rich

They should put those stickers on nitromethane too......

Have you taken a vacuum reading yet; Are you low? bolt a lift plate up on top a carb gasket (or a piece of sheet metal to seal carb pad) and pull the rocker shafts to close all the valves. plug all but one vacuum locations and chuck it to some compressed air. give it a shot and listen with a stethescope for any hissing or bubbles from a light soapy mix in a squirt bottle. A sprayed leak will cause bubbles. We 'flash test' airtight splice cases with same procedure and can find any pressure leak on the seams down to 2 psi. should find any vacuum leak with this method too, but ones under the intake will be audible only.

Just did this last night. Flat plate and welded an air hose fitting to the center, and mounted onto the manifold. Soapy water with air pressure at 20 psi, then 30, 40, 45, and no bubbles. Should be good here.
Thanks for mentioning this.
