Looks good. Did you pressurize the throttle shafts to keep it from leaking through there?

Use a marine holley. They come sealed. and someting with the primary metering plate is special. the powervalve is load referenced or some ****. they come with the plastic floats.





nikkis work good and webbers.



I did not have a marine holley and had some issues. Marine carbs are expensive. used there like 200 give or take. Im using a new carb not a holley and not a nikki or webber.



Un related topic It might not belomg here but I feel at home in the Fb section.



What are we trying to do. boost high compression motors. So with e-85 Ive hear u can run crazy high boost with high compression rotors. because it has a mutch lower egt than gas there fore it is less prone to detination. does any body know more about this and is willing to talk about it
