Angry Engine Damage

please allow me to scream...

AAAAAAAAAAAAAAAAAAAAAAAAAH

ok, im better. last wednesday when my rc10gt ran away on me and bent the chassis, i took a quick look and everything else seemed fine... until i decided to take the engine apart to clean it.

the engine was ceased TIGHT, it wouldnt budge. so i opened it up, and to my relief the piston arm was broken. so i figured what the hell eh, cant be more than a $15 dollar part.

so i pull the rest of the engine apart and remove some of the metal flakes in the crank case. but when i went to reassemble it i noticed part of the inside of the crank case was broken around where the little knob at the end of the crankshaft connects to the piston rod / pull starter

the piston and sleeve are fine, but it would still cause a problem wouldnt it?

id hate to buy a new engine if i just need a piston arm :\

im not sure about duratrax engines, never had one. but im sure somewhere on the next is an exploded parts diagram (unless you drive like i do, they you need a diagram of the exploded parts... LOL! get it? ahem... i dont have to impress you) and there should be a nut of some sort to tighten the arm down.

hope that helps...

actually... dont the evaders use O.S. engines? i could be wrong.. but if they do most OS car engines have a brass nut around the LSN (in the center of the throttle arm) which holds the arm on. maybe it just came loose....

id say download the manual and reset the carb. then tune it to your liking. im assuming that you made sure everything was tight and you broke the engine down and cleaned it out good. if you did that, and youre sure its not a problem with your glow plug or glow stick, its probably just way out of whack. or dead.

how old is the engine? how much use does it have on it?

I bought the truck in July and its had about 20 tanks (7 for break in) so its new! but i think i solved the prob. i think its a very very small compression leak under the glow plug. (i put a stage 2 head on, so the gasket has been taken off and on a lot)
