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!
try an odonnell 77t plug,or an os-p3. set hsn to flush along with lsn. then turn hsn in 1/2 turn and lsn1 1/2 turns in. then fire it up. One other thing you may have an air leak around the hsn. Take it out if above fails and with it out blow through pressure line off of muffler. put rag under the top of hsn opening and see if any thing comes out. I had some rubber from the seal come out on mine. Got new seal put some soap around seal so it would twist with out tearing. engine ran fine. One last thing, check to make sure your head bolts are tight along with glow plug. To me it sounds like a weak plug,air leak fuel lines? It will be some thing easy. also our idle could be set to low causing you to set the lsn to rich,then setting hsn to lean. I've done it.
