John, are you referring to electrical contact cleaner? I've always used brake clean, and yes, I've had several slip while torquing the nut. I'd sure give this a try if you say it works better.
Thanks, Dave

You must have oopsed on the timing adjustment procedure. Your timing is severely retarded, with those symptoms.

Yes it does. Take the amount of rotation while the piston is at the upper stroke and divide it in half.

I've heard of timing pins being off as far as 5°.

I always use electronic cleaner since it doesn't leave residues like brake cleaner does.
