Finally got the Venturi in, put four flights in on it, way rich the first one but 3 that were nicely lean, just little the little 25 spin up and stay there. Also put a heavy hub on the front to calm down those silly Ringmaster throws. This only because the muffler I had for it was the wrong thread for the bolts I had (from the tounge muffler on it now) I'll get the correct bolts and swap mufflers, I think that will be a better match between extra twitchy and smooth rock.
Anyways, the motor isn't a problem now, just some flappy monokote. Ready for next weekends Flyathon.
Thanks.
