I have 6 Poulans ranging from the cheapies to the 50cc Poulan Pros and they all have to same coil, none of which have the bracket you had to remove. Unfortunately I sold the only Wild Thing I had, so can't use the coil off it. I find it strange that it used a different coil configuration, I always thought it was the same as the other saws in the line up. I have a spare coil for the Poulans so I'm going to try it hoping it operates the same as a Wild Thing coil, just have to make yet another bracket to mount it in the XL-76. The L mixture screw only adjusts the mix for idle speed. It's the H screw that sets the mix for high speed full load operation and it's important to have it set so rich that it has a distinct burbble sound to the exhaust (called 4-stroking) when running at full throttle with no load but cleans out and runs with a crisp sound as soon as it start to cut.
