hello there looking for some help with a Tecumseh hh 160 engine 2 things when you go to start it ......it will quickly backfire split second and take off run real good no issues but it does this every time you start it i'm thinking a timing or valve issue? also second looking or need info to get electric pto 1 1/8" shaft I found one off a kohler and had to build a inner race because the the stationary plate is some how rubbing on the solid piece and still haven't had good luck to cure it so if somebody could put me on the right one that would be great or show the pic of the right one or where maybe to get a new one for the bolt pattern of this engine

Intake valve should be set at .005, exhaust at .010. It could cause backfire if they are too lose or maybe tight. They can also cause hard to turn over if not set right.
Timing is pretty much non adjustable. The two trigger pins in the flywheel are fixed along with the flywheel/crank key. The SSI module has a little adjustment, but not more than a couple/3 degrees.
It could be your compression release is not functioning properly causing the issue, but I couldn't be sure, I haven't had to mess with mine.

I agree with Tecumseh power.
I believe the the two pins are meant to have different air gaps.
The pin that should help with starting and idle should have a smaller gap.
In you can find a Tecumseh service manual, there is a diagram that explains it clearly.
