TT-(Moderator) 1,127 #2 Posted August 6, 2012 You only need enough pressure to keep the proper level of fuel in the float bowl. Anything beyond that is a waste. Share this post Link to post Share on other sites

Deere Hunter 54 #5 Posted August 7, 2012 I usually run between 2-3 lbs when running gas. It all depends what the carb will take, run to much fuel pressure and you will have it running out of the carb. Start at 2 and see how it runs and adjust from there.

Jim_M 178 #6 Posted August 7, 2012 I agree, 2 or 2 1/2 psi. What are your other carb questions? Share this post Link to post Share on other sites
Fast N Red 5 #7 Posted August 7, 2012 Where do you drill the hole in the carb when you plug the two vent holes Share this post Link to post Share on other sites
Jim_M 178 #8 Posted August 7, 2012 I assume you're talking about the bowl vent holes being plugged after installing a velocity stack. Just drill a small hole in the carb body in the round area above the float bowl, keep the hole above the top of the float. I like to insert a small tube or hose barb and run a small piece of hose up the side of the carb to keep it from sloshing fuel but it's not really necessary, you have to have a pretty rough ride to slosh any fuel out.
