Pulled her from the shed a couple weeks ago and it works like #*$&@. Idles rough with a bad miss, not running on all 3 cylinders. Tried new gas, cleaned the carbs, checked compression (190 lbs on all 3) coils checked out good on the workbench. Seems to be ok at startup but then loses a cylinder when warm. Any thoughts ??? Valves out of adjustment?? Coil breaking down???

you did run a wire through all the jets? pilots plug easily on these motors. have you replaced the fuel filters lately?
Yup, all jets clean as a whistle, never replaced filters but didn't seem to be any restrictions at all on the filters in the tank. Seems like i get strong smell of gas when she starts acting up. Thinking I have a coil starting to break down when it gets warm??? Is that possible??you did run a wire through all the jets? pilots plug easily on these motors. have you replaced the fuel filters lately?

it is possible. try running it without the rubber boots on the coils in the dark. if you have a light show, they are most likely bad. might only do it when they heat up as well, so let it run for a bit.
