ORIGINAL: Tony Hallo
A friend was planning to purchase one these at Toledo, the display engine had the same same problem, tight at BDC. I talked my friend into waiting before taking the jump. My reasoning to him was if they can't take the time to make the Toledo display engine good, what makes you believe any of production models are better? The asian man behind the table said it was tight because of compression, I showed him the exhaust port, laughed and walked away. Another person at our club bought one at Toledo, he wanted the S version, they gave him the S heads and asked that he send the straight heads back to TBM once he makes the change. Wonder if his warranty is intact? I hope it works out for him, I rather take my $420 to the Rivers Casino in Pittsburgh, I can loose it there just as quick.
Tony,
Tomy the owner of MT was the asian man at the show.
That explains a lot. My Engine IS the one that was displayed. Tomy installed the "s" cylinders on it after the show to take photos, sent the engine to Jack to ship to me. You would think the display engine would be flawless. You showed Tomy the engine is screwed up and he ignores what you say then sends it to me and says there is nothing wrong with it!
Hard to follow manufactures instructions when the engine comes with nothing!
Regarding the binding,
If I leave the forward exhaust side cylinder screw loose it doesn't bind as bad. It feels like the needle bearings are binding do to a misalignment of the cylinder/crankcase.
