I used the heat cycle method running on the box using heat gun to regulate temps 210-212 F rich for five tanks, before I set it on the track and started tuning.It ran great, love the engine! I also had plenty of smoke exiting corners
I've never sucked dirt or ran to lean It seems to run its best around 200-230F running stock header with o53 pipe OS#8 or A3.Now all it does is lean bog and flame out!!!! I had a few of my race buddies check it out bottom line needs a pinch.Also do you think I should attempt a pinch with an e-bay sleeve pincher? I have seen guys use these but,I have not. What is the error margin & how accurate are these, If I take my time and rotate making small adjustments.
Let me know what you think....
raya racing is the guy
sounds interesting , something had to have happened to the engine for it to be done after only 4 gallons
those are both very hot plugs , i dont care to discuss anything with plugs anymore
