Check all the seals for leaks. A leak into the crank case on a two stroke will cause a lean condition and soon seize the engine. Also the exhaust will determine where the powerband is so how is the pipe? Dented, smashed or as new? I assume you are testing with a load (Prop) It is posible that if your freind built a custom exhaust it is just not designed right for this engine. It occured to me while typing this that I once pruchased a honda Odessy for $100.00 the owner thought it needed valves;-) Had good compression good spark and I rebuilt the carb, even tested it on a snowmobile. Once I got it together it started on the first pull, but would not run faster than an idle. After several hours of fiddling I cut the pipe in two right at the expansion chamber. There were several years of mouse nests. We ran that Odessy for 5 years I sold it last sumer for $1200.00.Try blowwing air through the pipe it should be an open tube with little to no resintance to compressed air. hope this helps Wayne ----- Original Message ----- From: ponds27 <pond...@rogers.com> To: KRnet <kr...@mylist.net> Sent: Thursday, May 20, 2004 5:07 PM Subject: KR> Looking for an Italian contact to help locate KFM motor expert
