Im not. I’ve done my research and received instruction from some very accomplished local pilots who have had excellent results with the 670 and the standard sled ignitions. I know there is plenty of disagreement here. I will be installing the engine and working through the final steps soon. My mentors have given me a tone of head starts down to almost the exact set up that works. Hopefully I am able to duplicate there success. It’s basically a 100 hp engine for under 2000. Got the starter on today. Need to drill and tap holes for the pyros. When your ready to go buck I will tell you everything I’ve learned.
Mike is hopefully doing mine. He is getting ready to step away for a year or so. I'm hoping he can get mine done. He said his boys might take it over also. I'm not worried about dual ignition. I'm going to run the hotter snowmobile ignition anyway.
I've been getting some info from guys flying them and I'm sold. I know the 94 case is best but I'm wondering if 95 or 6 are doable. It's been hard to find a 93 94. I'm sure it will happen I'm just anxious. I already have a pipe on order for it. I'm going to bore it and run 79mm pistons with this pipe and it's supposed to dyno well over a hundred horse.
