I found that the carb slide's set screw nub hit's the back-angled part of the fuel tank. I actually had to grind some of the nub and set screw at an angle, as well as, turn the carb slightly to the right so that it will clear that part of the tank, but only by about 0.5mm.
Yes, have the same issue, but opted to grind a notch out of the radio top plate instead of the carby, but also have to have it on an angle.
Awesome motor, it's a shame you can't get back up support or parts for them. especially the cranks.
