i thought i knew a bit about motors but this one has got me foxed,it is non-rc with a black plastic venturi,takes standard size plugs,the muffler is an aluminium ring sandwiched between lower cooling fin and case a la cox,the muffler has 1 hole about 3mm for the gases to exit,it is marked as a 15 but doesn't look that big and the case has what looks like a 'j' cast into it,the case backplate screws into the case,it has beam mounts as well,help.

It sounds like a PAW, they either made or converted a few to glow engines at one time according to a poster here a whole back.

it's not a paw glow conversion as i already have one of those.

I guess by your description it it looks somewhat like a PAW.

no.it looks nothing like a paw,my gut feeling is that it is russian or czech.

Sounds like a Cipolla Jr. although I thought they only came in the .09 size. Mine is an earlier version.

Edit: The 15 is actually 1.5 which means 1.5cc or .09 ci.

thats the one!who made them?btw many thanks.

Cipolla is Italian for 'onion' (pronounced "chi-po'-la").

I hope it is not a 'lemon'...

<GGG>

bigchap,

A little additional info, I was thumbing through a 1978 Aero Modeler magazine and saw an advertisement with the muffler version you describe. From what I understand, the Cipolla glow has a decent reputation but the diesel version tends to throw conrods. I do not have the diesel version so I am only repeating from what I've read on the web.
After I broke mine in, I found the lower conrod fit to be a bit loose, but this may be normal. I don't have a lot of time on it.

George

thanks for the help
