Damn now I am scared I screwed up my engine after reading that link. I went to that devry bash spot to break it in. Nice little spot too, 5 minutes from my house.
Maxximum, I just broke in (attempted too) my engine this weekend and after five tanks I think I am having the same problem as you, it just wont start. Below is what I did for breakin, probably wrong but I am totally new to this hobby. Maybe somebody could read through what I did and tell me if I messed this whole process up. Thanks
The engine is a Dynamite .12 SPD Pull Start. I had some problems getting it started at first, but once I did get it started I let it Idle with the wheels off the ground for the first tank(Mistake mb). Then my son and I ran it on the ground for tanks 2-5 blipping the throttle between idle and half throttle for a whole tank. I fouled a plug and installed a new one. The head never got hotter than 200ยบ I think, but I dont know cause I dont have a temp gauge so I spit tested and the spit just kinda of bubble away but not sizzled. I know I was running rich plus I used Blue thunder breakin fuel. I few times I think I might have had Hydro lock and didn't realize it. I also had some fuel bubbling out of the glue plug hole(air leak?). I also never got the White blue smoke really. I did have some fuel spitting out the pipe. I got it started once on the sixth tank but she quit as soon as we got her on the ground and hit the throttle. After that it didnt start. I check the igniter and glow plug and the plug was heating up. I also noticed that the truck creeped less and less forward at idle with each tank. I did kill the engine when almost out of fuel and let it cool with the piston at BDC. I also noticed that my high speed needle felt spongy when I turned it, is that normal? The piston still is kinda of tight at TDC even after 5 tanks. When I couldnt get it started anymore I dumped the gas and put some after run oil in it. I am going to get some new plugs and try again this saturday or sunday.
