Hey All,
So I'm working on my nitro I got for X-Mas, don't know what brand it was but the engine is a VX-18. It was running pretty decently for a while, then I had a kind of rough crash, it was bad enough to snap a wheel stub axle and I *think* it broke the clutch shoe spring. (the damage to the clutch assembly may have happened after the fact on the below issue)
I replaced the wheel stub axle; after trying to run the engine either due to rpm or clutch damage, it kept the clutch engaged/truck wanted to run off.
So then I replaced the flywheel, clutch shoes/spring, and clutch bell. All *seems* to be installed properly, but no matter what I can't get the truck to stop wanting to run off. The rpm's sound high but I'm not sure.
It seems like it's running lean (high rpm/running away), but at the same time rich (often wants to stop right after glow igniter is removed). The only way to get the engine to run on it's own is tune it closer to lean but it still wants to roll away.
tl;dr (too long didn't read)
I know there are lots of variables but I hope someone can help.

- factory engine ran well
- crash
- broken axle and burnt up clutch shoes/broken clutch spring
- truck still wants to run away
- seems lean (running away) but also rich (sputtering and engine stop on igniter removal)
- also spits out the excess fuel when I do start to lean it out and run more properly
- also tried needles at close to factory settings with no luck
