Small 4 stroke engine ring positioning?

120 degrees at install. New rings? Check ring end gap, push ring square into bore (use top of piston), measure gap w/ feeler gauge. File to fit. Make sure rings go on right-side up, bevel on top. Go to Briggs website for torque and assembly specs., or to find local outlet. DON'T HAMMER ON BEARING SURFACES!!!

You will need to know the ring end gaps. You will need a model type and code of the engine to access this information. You can then go to Briggs & Stratton website for help with these values and getting a repair manual.

There are 3 rings. Each ring is 120 degrees more than the first one. Yes they will move but you want them to start with each ring 120 degrees.

Briggs & Stratton told me they have no torque specs or service information for this engine. Only thing they could give me was another owners manual from mitsubishi. There should be a law against a manufacturer not providing service information for a product they sell even if it isn't their engine.

I put in a new governor control for this troy bilt model 01923 900 watt 4 stroke briggs & stratton engine & I believe I did that successfully. It seems pretty solid in there & it fits tight with the crankshaft gear unlike the worn out one.

I figured out that you should measure how far the rod sticks out from the outside before you knock it out towards the inside of the motor. That way when you put it back in you can get it very close to where it was to begin with. You should also put the rod back in by itself first, then when you have it positioned correctly you can put the governor control over it & snap it down on it. When I tried it all connected to begin with I couldn't get the rod to come through on the other side. You can also use an extension & a small socket that will fit over the rod to hammer it down straight.

Now my question is do I need to move these ring gaps into any certain position or should they just be 120 degrees apart. I've read that they move into their own position anyway so I'm suspecting it doesn't matter.

Also, I can't find a shop manual for this engine so do I need a torque wrench to reattach the rod to the crankshaft or should I just tighten the hell out of it & make sure it still rotates around the shaft?
