Hey guys my uncle has this old gas engine on a big ugly stick. He said that the motor is atleast 20 years to 30 years old? Can anyone help us with the brand, it has a walbro carb(not much help) and it swings a 18x6 prop good so just tell me what you guys think.

Quadra Q35. A tough old, reliable engine.

thanks fly paper....

Given the old steel prop hub, it could also be a 40cc. Pull the muffler and look into the cylinder. 1 ring = 35cc, 2rings = 40cc. Bennett's web site has exploded views and parts for these engines. Your's most likely has points as well, consider a point eliminator if you have any glitching problems (been there already, I have a 40cc).
