LOL, I wonder if he'll come back to answer you. To be honest, I've put mine aside for awhile due to tuning during break in too. cant get it to run for 2 minutes without dieing. think the lsn may be TOO rich for one, but I've piddled with it for 6-7 tanks, got frustrated, reset it , sealed it and did a carb swap to see. In the end, I've set it aside for awhile so I don't just give up on it. (5 port with 1.42 factory lsn that I got new last summer) Never had an engine give me this much grief during break in. Interesting for sure, and I could just feel the potential,when it was running, but it got my goat so to speak. I'll go back to it in a few weeks I guess. In the mean time I'm breaking in a budget Nova 3 port, Not expecting as much performance as the Go, but dang it! It started right up! LMAO Not sore on Go, just frustrated. Especially since the 3 port Go in my buggy runs so good!
