Hi Phil.. I'm not sure how you can fix a compression issue properly without taking the head off and checking the valve seals and seating so any pointers would be welcome. I have put in a Wynns oil additive to help but I'm not convinced that the 3 point difference would make much change to the tick over. It was fine before and it didn't run far at all when the gasket let go.. I got it towed home. The biggest difference is when I took the pipe from the idle control valve off and air was freely flowing into the throttle body. It increased the tick over speed a tad and was noticeably smoother at tick over and brighter to drive. You also noted a miss fire on one of the ht connections and maybe I should look there as well. It is frustrating not being able to adjust air flow and mixture... Having to wait for the ecu to learn any change.. Without a T4 to set anything is crazy for an old school Morgan owner like me.. Any thoughts would be welcome.. Thanks.. Mike
