yeah, after he screwed up my crank i rebuilt the engine myself which took 2 weeks with about an hour every night.... the only reason i didn't catch the thermostat being in backwards was because i left the housing on the intake manifold. and luckily some college students aren't so bad at building engines. my engine is running excellent now that I've fixed all the problems that were caused by my idiot friend.... now the only problem i need to fix is the air fuel mixture on my carb so I'm not pulling a pathetic 8/mpg
