I posted last week about my tuning issues with my 3R. I tried the suggested 2.5 turns in on the lsn and flush with the HSN. It wouldn't move when I put it down on the ground. It revved up, albeit not that high, and blew a nice cloud of smoke. Only after turning the hsn a turn in from flush would it take off. It ran okay today, but not GREAT yet. I can feel this engine having lots of power if I could just tune for it. Everything I know about nitro tuning(admittedly, not that much) is thrown out the window on this Go engine. I think the problems with Go are only partially the carb, and mostly the way they tune.


The track I run at has a long back stretch with a big double and a huge triple. Basically, when I got it 2.5 turns in on the LSN and about a turn in on the HSN(only way it would move), it would go around the track, but it would really struggle when I pinned the throttle to get over the double and the big triple on the back straight. I would describe the sound it made as a tearing sound or a raspy sound at full throttle, and it would kind of plateau. There's also a cross over on the track that you have to get pretty close to full throttle to make it over, and it would make the same sound there. The first few laps, it didn't have enough top end to get all the way over the double, let alone the triple. After a few laps it would make it over, but still make that noise at full throttle.

Other than that, it ran well, temps around 210-225.

Should I have left the HSN at flush and just fiddled with the LSN?

Help is much appreciated of course.
