We should really take this to PM's...
I've set up a bunch of T.H. engines so I've been through the wringer on all of the problems ( which tend to be user caused! ).
PM me if you wish to discuss...
If you feel the need to got to pm's that's what the option is there for.
On the other hand, yetti831 asked specifically for an opinion of whether or not the OS55 and the TH46 were equal and seemed to state that they both advertised 1.75hp @ 16,000. So it's quite sensible to answer that question right up front. And to discuss the power@rpm issue too.
