My vote goes with Pete. If I know that sanye makes it I'll let others take the risk while I will go for the sure thing, like OS , Saito or Thunder Tiger and I do know how to tune and run an engine.
Just purchased a NIB Magnum 91 4-Stroke. The HS needle is so loose that I was afraid it would fall out, but after sliding some fuel tubing over the HS needle the engine runs ok, this has never happened on any of the OS,Saito or TT engines that I have owned.
