Quite often a bad aluminum flywheel ring is what starts eating the fiber starter gear and it only takes one bad tooth on the flywheel ring which is easily overlooked. Also the China Clone fiber gears are weak.
(Briggs had a starter aluminum flywheel ring replacement kit but it's now a NLA item for the opposed twins.

I keep a eye and ear open for old Briggs flywheels that have been thrown out due to bad stator magnets and quite often they have a good flywheel ring.
Just grind the head off the rivets and then use 1/4 20 screw/bolts to mount instead of rivets.

Star, that’s what I call a hog ring. C-clip to me looks like a snap ring with no holes for a pliers. Some people call them E-clips.

Flat C clips [just one of several designs. This one has holding power and some don't list the transaxle axle C-clips. They can come is round wire types too. Just depend how far the C is made.

I’m just showing my age and background. I guess we’re just calling them a different name, but we will end up with the same results When using the proper one.

I worked office for 16 yrs and cam across a lot clips and rings. I have come across Speared End snap rings when I was tearing the 4L60E transmission. luckily knew a mechanic the right angle snap ring tool it required being a tight spot.

And there is at least other version snap ring that not picture that was use on VCRs.

And even Stens apparently don't know the difference between Inverted Internal rings and External rings

or for us that a business account with Rotary; they are PN 10233. Of course we have to get them in lots of 10.

As for flying off that why you use a rag.

A piece of painter's tape works fairly well. Put it on the tip while working the ring off with a pair of pocket screwdrivers. If anything, it slows it down from jumping off into never see that again land.

If you would give the engine model number, we could verify what starter pn, but since you won't, try this info.

Just the gear is https://www.amazon.com/Everest-Bend...h+plastic+briggs+starter+gear,aps,139&sr=8-10

Gear kit in case you drop anything: https://www.amazon.com/dp/B085WX473...c2ff18f5c&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWwy

And if you want to get a metal gear, this has it: https://www.amazon.com/dp/B0CSK3VDQ...=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&th=1

But the plastic is used for a reason, a metal flywheel gear.

Make sure the motor shaft is clean and smooth. Gear should slid up and down, freely, as you turn the gear CCW. Check the flywheel for burrs.
