Where can I find the following info?

[mannmoney]

I picked up four used Losi LST2's from a neighbor who was leaving the area.The trucks were pretty bashed up and I was able to replace the chassis parts, but when I went and tried to run the trucks the problems appeared. Two of them won't engage when I rev the engine and the other two won't start. When I use the starter the engine pops a few times and than acts like there is no compression. I've tried to use the info in the manuals for trouble shooting but I can't find what I'm lookin for. Would someone please direct me to the where I can find the trouble shooting tips I need to fix the problems.
Thanks

Won't move when revved = bad clutch maybe.
FIX = Take it apart and do maintenance on it.

Won't start/like no compression = worn out piston-sleeve fit. probably.
FIX = If you can turn the motor thru a full 360 degree rotation of the crank with little or no "pop" at the top of the stroke, it's too worn out. Replace piston & sleeve, or have the sleeve pinched to tighten it up and get a ew piston. Or replace the engine.

Good score though. How much did they set you back, if you don't mind sharing?
