Ryobi starter dogs

[38racing]

I am working on neighbour's yardmachines 2 cycle cultivator with the ryobi like motor. Was changing fuel line but recoil went. . The pulley knobs were worn so I replaced it with one from a parts unit. But when apart I see that one dog is broken and I think the other is bent.
Here are pics of his flywheel and the parts one . When I put it back together the recoil will not retract when housing is tight. I'm thinking it's the bent dog. Am I right in my thinking here?
And how hard is it usually to remove a flywheel from a trimmer motor. Anyone recall if this forum had a thread on that recently?

Hey 38

Not trying to be picky, but you pictures are so large and fuzzy,
its hard to tell anything about the dogs.

Seen it before - any excess resistance in the engine rotation, timing issues, bearing binding, carbon build up, backfire, and even simply just rough handling during starting - yanking on the starter cord too hard can be all it needs.... (Owner loaned it out to his muscle-bound nephew..) , will tend to bend those cheap, lightweight metal dogs - once bent, they are not fixable - they just bend again, even if you are able to straighten them -

They are also not available as service parts, but the replacement flywheel assembly is quite cheap actually - around $20-$30 if I recall...
However.. so far, each time I've had a customer faced with the repair estimate (parts and labor) , they did one of 3 things:

1) Told me to junk it (scrapped and recycled)
2) Took it home and tried to fix it or tried to get other shops to fix it.
3) traded it in on a new Echo TC-210 (We only give a $10 "token" credit for such trade-ins.. and they still always end up on the recycle pile)

crystal clear when I click on those links. Was going to resize but they were less than 1 MB so I left them.

I thought if the flywheels would pop off I'd try to swap with my parts unit.

Sounds like something on my end.
I will check myself. Sorry.

They do.

Flywheel part number 753-06221 - Runs about $15-ish

I'm hoping my parts unit is a match, looks like while on units. My parts look up leads me to 753-05240 which runs at $36 compared to $11 for 06221 from one supplier who has both. And life would be so much easier if all the pulleys looked like this one.

If you post the models of both units I would double check your cross referencing. There is usually a good for different part numbers as the size and weight may different between the two units.

On ereplacementparts.com the 753-06221 is being for only three Craftsman trimmer versions while the 753-05240 is being showed for 150+ models.

Got both off. Identical except for keys. One narrow with separate key .other is wide keyway on shaft and builtin key on flywheel.
