I pulled a 14 pound midwest AT 6 with a Webra 120, and was impressed except some carbueration oddities. I had a pump added and carb modified by UAV and performance was superb.

If you want a Webra 120 on steriods, get the UAV 120 PR. Twin plug, and my experiece would justify their claims of greater performance.

I don't know why a dykes ring would wear sooner. Its subject to less wear. You can touch the crankcase of a webra 120 running at full throttle and it is cool to the touch.

Just don't reach for the case from in front of the engine. Things will warm up in a hurry.
