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

The OS 60FP is a bushed engine and needs more oil in the fuel

The standard air bleed carb is normally trouble free and very effective.

I don't think it would be cost effective to change the carb.

Max, the carb on your RN is essentualy the same part as the original version, you just have to buy the needle/spray bar assy for about $18 from tower and screw it in where the nipple is now.

I have two of the .60FP and I think carb works pretty well. I don't know if the perry/conley carb would be better, I have never tried one on this engine.

The .60fp is a bushing engine, so use a fuel with some castor oil in it to extend the life of the bushing.

Here's the manual for the 65LA which replaced you 60FP. they are very much alike
