I got around to checking the 049's , the guy told me they were 113cc and I see there 120cc+. Good thing I didn't take the time to go look at them. So I bought the L29's. The threads I have found are promising but I would like as much information as I can get on these. I'm going to use this 489 on a Direct drive Airboat so torque is the key as the thing won't be turning over 3200 RPM. Any info and tips you might share sure would be appreciated. Thanks!
