Hi Grumpy, thanks for the compliment.
Good to hear the gasket is good, it is soft and slightly flexible. I was thinking that with all the pits on the top side it might of been able to let air leak in around it. Thats sorted now. Your not going to believe me but the inside of the carby was virtually spotless, it looked as if was had been cleaned recently. Should i put it back togehter and give it go now or should i go deeper.
Curious question, the way it sounds to be running could i have put the motor back together maybe 1-2 teeth out. I am 99% sure i done it right, piston at TDC and all timing marks lined up just as it was when i took it apart, just starting to second guess myself. I supose if it comes to it i'll have to pull it down to check, not yet though.
