Do a vacuum check and it will give you a good idea what is going on. Make a vacuum port if you don't have one and Google vacuum check. Just maaaybe sticky valve guides. I swear by Marvel Mystery oil. I squirted some in a bad cylinder and turned it over a few times. It had 50 psi and overnite it dissolved the rust and crud around the rings and it popped up to 158. Runs like a scalded dog. With wo' out valve guides a valve will fall in the center of the seat for several rotations then fall crooked a time or 2 and loose comp. Bad rocker arm geometry will wear out valve guides early. |

Firing order is 1-4-3-2 & you need to run it to set the rings . Good luck . & where are you from. |

With it running right you might miss that 6 rib. |
