Hi Jeff, belt is not tight, just enough to stop it slipping. I also tried it with an unrestricted decomp and it kicked back. One major issue is that the pull start most times comes out about 200 mm before it catches, but in this situation it is that first 200mm that is important. Nothing I can do about that, and I believe it is the gearing in the way the pull start has to turn the motor from the center of the crank pin does make it harder to pull over. This added to the extra weight of the belt and disc make this design very heavy to start. It is a hell of a heave to get it spinning fast enough to fire. I also think the extra weight of the heavy boss is a bit marginal and another 50 grams would help. I have asked the seller with the heavy pulleys to weigh one so I can see how close it is to what I am using now. Sure I can send it back to the owner but I'm not sure he will be able to start it, he isn't a big bloke. I was also thinking of fitting a longer pull start cord and somehow set it up like the mowers that have the guide on the handelbar so you can stand behind it and really put your shoulder into it to get it spinning. Once it fires up it is fine, just getting it fired is the problem
