I finally got to run my truck and see what it's got. At first, it was having trouble shifting, although i kept leaning it out 1/8th, it still wasn't shifting. Then, i changed the shift point counterclockwise 1/2 turn on both screws and richened it a bit from before and it shifts great now. The only problem i have, which i think may be the idle. After warming up my LST, when i let off the trottle, the rpms jitter, and then it engages in gear and tries to move. It only happens after i warm it up. It's making a good deal of smoke, and never dies of overheating. I haven't had the chance to temp it yet though. Could it be too lean? Or is my idle too high? The idle seems perfect when i start it up, it's just after i run a few high speed passes on my driveway/yard. Possibly an air leak somewhere?

sounds like it maybe too lean on the lsn or Idle set too high. I would start with the Idle and see what happens.

I have heard that the Mach .26 idles high. I just keep mine just low enough so that it does not move forward.

i think i know the idle you are talking about (suddenly goes high pitch and the rpms jitter and the truck starts moving, quite scary the first time you hear it sounds like its gonna blow up). from my experience, its caused from being a bit too lean. fiddle with the needles

Kevin - EXACTLY! Alright, i'll just richen it a bit, although it seems to be producing an efficiant amount of smoke. Although, just by the amount of smoke isn't always acurate. Thanks for the replies guys.
