I still haven't got this OS .60 FP engine dialed in to my expectations. I have a couple more questions about it if you guys will indulge me a few moments.

Does anyone know where I can download a manual for this engine online?

Is this engine a bushed engine?

In an earlier post about this same engine, someone responded that he thought the OS carb on this engine was vastly superior to a Perry carb. Bear in mind that my engine has a remote needle valve, and I am not crazy about that idea at all. Do any of you folks have an opinion as to which carburetor would perform best on this engine? I see in Tower's site that a carb with the needle in the carb is available, but it would be over $50.00 with tax. I can buy a Perry for less money. So which is best: the OS carb with remote needle, the OS carb with needle in carb, or a Perry carb?

I also noticed in Perry's site that their model 1300 carb has a .270 throat diameter. This is the same as the OS carb. But a 1301 is also available that has the same outside diameter barrel and a .312 throat diameter. Would the larger throated carb improve the performance of the engine or would it flow too much fuel. Seems if the air and fuel mixture were proper, and the exhaust large enough to allow the engine to breathe correctly, the larger carb would perform better. At lease it works that way in automotive applications. Is this still true in RC engines?

I bought this engine as new and unrun, which it appears to have been, but it had been previously owned. I did not get any paper work with it--thus the question as to where to find a manual. Any info on the engine would be appreciated.

Thanks, folks
