I just got a 1/10 scale buggie from Ebay, a D&A model. Buggy looks nice but cheap. My problem is I can't get the engine to run normal, it's temp shoots up to 300 in just a matter of a couple of minutes. Now this thing is NEW and should have been set up for BREAK-IN from the factory. I have tried to cool it down with low and high speed screws with no luck. The low spped screw has just a small range of adjustment to even get it to start (about 1 1/2 turns), the high speed screw has more room but I can turn it in to the point where it no longer runs and it still is getting HOT. On the first start up (break-in) I let it idle with just enough throttle (factory settings on engine) to move it around and within 3 minutes the temp went off the scale and melted the glow plug wire.
Any ideas how to break in this thing without roasting it?
