We restored my 44 H about a year ago. Haven't driven it much, just a half dozen times, but we've noticed it does not seem to run as smoothly as it should. This was a major restoration, including needing to rebore the block, install larger pistons, etc. New bearings, new valves and more. So today we decided to check the timing.
We marked the first notch on the pulley (plus the pointer) with a little white, so we could see them better. Then, using a timing light, we started it up and took a look. Without changing the distributor, the light showed the notch about a couple inches short of the pointer. We tried rotating the distributor, and the closer we got the notch toward the pointer, the worse it ran--like it was struggling under load. When the notch matched the pointer, it was actually lugging down to the point of almost quitting. So we moved it back to the original position where it runs reasonably, like before.
Any ideas on what's happening here? Shouldn't it be running right in time and smoothly when the notch matches the pointer? What are we missing or doing wrong?
Thanks in advance.
