so first off i did a topend rebuild and once i started it up, it smoked a lot and burned oil. so i split the cases and replaced all the seals. one of the crank seals was the problem because it was damaged. so i thought this would correct the problem but i guess it didnt. after putting the new seals in and starting it up, it smokes a little bit, barely so i think its okay. but the compression is only at 100psi. and my elevation is 470ft. also when i try to start it, sometimes it will start first kick, then another time it could take over 30 kicks. another thing is after replacing the seals, i reused the metal head gasket. could that be my problem? could reusing that cause the problems i am having? i would appreciate any advice or info, thanks everyone
