Hi
Acquired this engine disassembled with new parts consisting of crank, rod, piston ,rings and bearings.
Have converted from gas to glow to run methonal and oil to get weight down for Gee Bee project.

During final assembly found that one big end rod roller is missing.
Looks like it should have 12 and only has 11 rollers that came with it.

So far have not found any information to identify it.

Approx bore 1.524in
stroke 1.204in
displacement 2.19cid
36cc
these are not dead on but close measure.

the engine is reed valve with nylon reed block.
case is made in front and rear half's
cylinder is held to case with 2 bolts
front case has 2 ball bearings
rear case has one ball bearing

The rear of the crankshaft has been cut off and an aluminum plug shrink fitted in rear sea housing.

Any help identifying what this engine is and who parts can be obtained from would be great!

Thanks
David

Dont know why pics didnt show up
Try again

The design speaks of Quadras. Which one no idea. They made a Q400 that was a 40cc single but I think they had side exhaust.

Thanks TKG
Have looked at every picture of quadra,ryobi,and other engine brands that I can think of.
Google hasn't helped.
The crank case could be someones home made but dosnt appear to be so.

Hope some one can identify this engine--or is it the only one ever made?

Will go to bearing house today in search of rollers.

Thanks
David
