Good morning Mike,
Thanks for taking ther time to attach the timing info!
My problem is that the pump has had a new coupler put on it at some point, and the timing mark on coupler (just a slight nick in one place) doesn't have anything to do with the pump it is now on, so I've had to set the timing by putting engine on 23 deress BTDC on #1 cylinder, and with the pump off the tractor, turn the pump so the pistons in the pump are in the same position as on another FSM I have when it is also set on its timing marks on # 1.
Hope I didn't lose you!
Anyway, it is running now without smoke, but does need a slight tweak, as it is not quite as smooth running as the other tractor.
Got awful busy with spring work, (-5C here this morn!) so will report back when I get a go at it again.
Thanks again, Mike!
...and best wishes,
