Ok, on my GT2, when I start it it stays good and still. But after it's warmed up, it begins to crawl a bit forward at idle. After it has been run for a couple of minutes, I can't keep the thing still without full brakes. When I let off the brake, it takes off, at about 1/4 speed. It gets worse and worse until it runs out of fuel.

*edit* Forgot to mention also, that my temperatures were quite high. Even read 270 once. I tried to richen it up a bit, but didn't make a difference. Also, when I apply the brakes, they just lock up. Everytime.

Simple....what's my problem, and how can I fix it?


History: I've had some throttle linkage, radio trim, and factory setting issues so far. I just took it to my LHS today to get those worked out. The guy tried his best, and confirmed it's running well, and fully broken in. However, adjusting the linkage to fully open the carb valve at WOT required actually turning the carb lever. It looked great, and would now fully open the valve at WOT. But we both forgot to check one thing.....the brakes. Once I got home and started it up, the brakes were engaged at idle. So I started adjusting the brake linkage, and finally worked that out. My radio throttle trim is set ALL the way to the left at 9:00. Yeah I know, it's all screwed up....plan on taking it back to the LHS again tomorrow. Day 3 so far, and still nothing but problems. Kindof disappointed it's turned out this way. I really appreciate all the help all of you have given me though. I'd have gone insane by now if it wasn't for you all.
