I have an old nitro stampede with a TRX .15 pro engine. I bought it used and have had it for years, but never have gotten it running well. Recently, I got it out again to try to get it working. I completely tore apart the engine and carburetor, cleaning and lubricating the parts thoroughly. To my dismay, I still couldn't find much that looked broken or overly worn. The piston and sleeve weren't scored or damaged (though they were discolored in some spots), the bearings were fine, and the crankshaft seems to be fine as well. The only thing that was obviously broken was the backplate gasket. I didn't have a backpate gasket on hand and I couldn't find one for sale, so I just put the engine back together with the broken gasket and sealed all the potential problem areas with Ultra Copper. I set the carb to factory settings and proceeded to try starting it. It occasionally buzzes for a moment and then quits, but never completely comes to life. I then played with the carb/ throttle settings, but still nothing. I don't think the problem is anything really obvious; I know that the engine is getting fuel, the glow plug is igniting, and that the flywheel is tight. I feel like there is decent compression because it is fairly difficult to turn the engine over by hand. I am really at a loss with this one. Could a torn gasket really prevent the engine from starting at all? I feel like the symptoms could suggest that the piston sleeve is bad, especially since I know that this engine has been run too hot before, but there are no signs of damage to the sleeve and there is decent compression... so idk :\
If you guys have any suggestions I would love to hear them. Thanks!!
