I put 53 m j and a 8.5 power valve. When your cruising and let off gas and get back on gas this is where my stumble or lean bog happens. So I switched back to 9.5 power valve and lean bog got better but still there a little. It doesn’t do it from a start going threw the gears flooring it and shifting their gears. Only if u let off gas then get back on gas this is where it happens. This is driving me crazy. I’ve bought all these Clifford hop iup parts and built this motor around all there specs from the website and Larry down there I had his machinist build my head. And the one carburetor Garou one guy that was supposed to be able to work the Dyno tune and it’s still not right.
