I have a 4 mil currently has tm38 carbs on it and it acts up at idle on right side pipe it doesn’t fire unless I press throttle and when it does it pops a little take off throttle and it stop firing as much on that side. The left side pipes constantly run perfect but it spits a little oil and stains my car (thats how I know).
Taking off it sputters a little but when it hits around half throttle it takes off like a bullet without any hesitation at all.
Absolutely no air leaks and compression is exactly 150 on both side. I run 93 pump on it. Also vforce4, has coolhead and shearer pipes.
