Topic: Your Fired!!!!

[Take-a-Left]

Hey Hey Fellas don't be fussin over little ol meeee. I got the mower runnin, head out on da highway......  Oh excuse me I'm weird like that. I took the cover off, pulled the coil, sanded the post where the coil bolts up, sanded the coil where it contacts the block, checked the ground wire connection, reset the air gap, and it fired right up. Don't know which one fixed it but its running and running good thanks for all the help!!!!

I have only replaced 4 coils on opposed twins in my 12 years working on them. And it wasn't the coil that took them out its was heat buildup from grass clippings...just my  I've serviced plenty of Briggs engines single,ohv,twins that were over 15 years old and never had coil problems.

Your one lucky dude I'd say, I have replaced more than that in half the years...

Back to your problem, what plugs are you using?
We had champions in, gave us the exact same problem, new coil no help, changed to NGK plugs and the problem went away...don't ask me why, just reporting the outcome..lol

I found the problem by laying a screwdriver across manifold to wire with plug in engine...engine would fire.
That tells me the champion plugs weren't grounding well!

Take A  Left, glad to hear you got her runnin.  Rooster, we have also been having problems in the shop with Champion plugs. we have switched over to Autolite with no problems.  My pulling tractor with the Kohler, It will only run good on champion plugs. kinda weird.

Ohh by the way its got my MOTOR runnin, headed for the highway.lol
