That is good info I was working on an old Briggs on a tiller this morning and
no spark. I sanded the flywheel but didn't think about the coil mounting surfaces, thanks. This tiller was on the path to junk dealer, now it might have new life.

Growing up in the corrosion capital (Buffalo) I learned early on about good grounding and the gremlins it can cause. Electrical connections can never be too clean or too weatherproof.

The machine runs good when it runs, but to start it, I have to hold the throttle closed with my hand while pulling the cord, and even then it only will start sometimes if I warm it up (bring it inside). The spark is pink and erratic not bright blue like I would like. I have cleaned the carb, it is getting fuel and has good compression, I think the coil is failing. Do these coils go bad? I am not use to replacing coils but I have been out of the repair business. Any help would be greatly appreciated!

Yes the coils can go bad.
Are you using a spark checker or a plug to check the spark? Could be a bad plug or a lousy ground on the plug/checker.
Also, the date code shows it being made on Aug(08) 4th(04) 2001(01)
And tells us nothing! It's best to post the Model & Type numbers.
Another thang......sanding the magnets and coil legs doesn't do a dam thing towards increasing the spark!
As Slapper suggested, a good ground is needed.
Is the coil set to .010 or so?
Prolly time to replace the coil.

ok, let's get back on point and the discussion at hand...no need to disrupt the thread and take it off topic

thanks, we would appreciate it
