Thanks Deputy,
I am running a 12/8 on mine. My engine is the "old" Webra 10cc.
I noticed today though that in climbing, engine seems to bog down. Thought it was too lean and richened it , but it didn't seem to help. Any suggestions on maybe installing a pump or pipe?
It takes the strap on muffler also. Right now using a straight muffler. It seems to me to be fuel or adjustment problem. Any thoughts ?
