I was trying to found a store where to buy ryobi parts.
I have four of them, and would be nice to have some replacement stuff. I know the reconditioned ones are too cheap, but bring them to Chile cost more than the machine itself.
I have been reading about the double ringed piston. I would like to get one of those and replacement bolts ( 1/4 " to 1/2" larger) for the rear black plastic cranckase that are Nº10 - 24tpi, but that I could not find here yet.

So:
Where can i buy the 2 rings piston, and the bolts??
a bigger carburetor may be??
Thanks.

Try this for Riobi parts. They have parts on .pdf which you can download.

Hi
Say does anyone have a model # and serial # for one of the twin ring wackers thanks

Do the double ringed engines has really more power or not???
It seems that the gain in power is not that much, as I read numbers in other forums.

P.D. outdoor distributors are what i was looking for. Thanks,
Tato.
