Most times  it's the carb but you can't even find the rebuild kits for them any more .

With a mini there's only two kinds .Those that run  fairly well or those that don't run at all .More of the later than the former .

If I need a ring and can not find a Cabor ring, I get them from this guy. If he doesn't already have them, you can send your cylinder and piston to him and he will make one to fit.

They are usually $15/set + the shipping back and forth

Sweet.  Thanks Jim.  Do you know if he does the really thin rings (such as .062")?

He makes rings for model airplane engines and some of these are thin like you mention

This link brings up images but you can select the web at the top. Not all the images have to do with him. He doesn't wear a bikini. In the web mode there is his phone number? Might be old #? 505-327-0696

So he doesn't play for the 49'ers either? 8)



Thanks for the info Jim.  Hoping he goes above 2" for thin rings, as that'll make things much cheaper for the Homelite 750 guys.  NOS rings have been listed on feebay for $99/pair.  Crazy.  I'll call him about some rings for my Poulan 4000 too.  Those are thin rings that are getting scarce.  The 82cc McCulloch rings and thin SXL-925 rings are still plentiful for now.

Speaking of 82 cc Macs it seems at least on flea bay you can find a lot of
"b" pistons but"a"s are rare .

Something dawned on me at work today .On these bastard type rings it should be possible to use a sutface grinder with a magnetic table to shave a ring to thickness providing the rest of the ring fits .

Years a go ,fact close to 50 now I had an Indian Warrior motorcycle with bad rings .It was the same bore as I think an Indian 741.Rings for the 30.50 cubic vert. twins were almost non existant even back then but the V twin 741's were plentiful .Bought a set for 4-5  bucks and had a buddy grind them to thickess ,worked great .Possibley another way to skin a cat .
