Have a Wisconsin VH4D. Rebuilt carburetor and was running great. Was showing neighbor how great it was running and cranked it up and I forget to put carter key in throttle rod and it went wide open. I immediately shut it off but when I went to crank it up again it would not crank. It would try to fire off some but would not crank. After a while it would not hit at all. I checked the fire and it seemed weak(looked orange) This model has a magnita. Checked compression and had 90psi on 2 and 75psi on 2. Took plugs out and put oil in spark plug hole and it tried to crank again but would not. My main concern is the compression. Could not find anything to reference it by. Any help would be greatly appreciated
