Not trying to be mean, but I can't understand what you are saying.

From what I did understand, I would recomend taking it to a experienced engine builder. There are a number of things you could have done. It could be the transmission. It could be valve problems due to misalignment of the timing marks during reassembly. It could be the crank, connecting rod, etc. You are just going to have to disassemble the motor and find the problem.

Good Luck
