I have completed building a P2 to M L Breeze design. I had great difficulty in setting up the valve gear initially but percivered with the best setting I could get. It wil only run light engine and is extremely rough when attempting passenger hauling which confirms my belief that the valve gear is wrong. I have spent the last two weeks investigating the problem to find a solution by trying to redesign the valve gear,but this is, as yet, unmade and unproven.
Has anyone else come across this problem?
If so have you found a solution?
