Engines Plugs Mufflers Fuel > Rebuild OS 32??

I have two worn out OS 32 F's (one is a pull start) Is it worth rebuilding with piston and sleeve, or should I just buy a new OS 32? Is there differences in the old vs new carbs etc?

Most definitely. The 20C two-needle carb on the 32SX is LEAGUES ahead of the old 3B carb on the 32F.

Having said that, my first Concept had a 32F and was probably the smoothest of the half-dozen Concept 30s I owned. I have always found ringed engines to be smoother than ABCs.

Two things to consider, Mike;

1. What kind of flying will you be doing? The 32SX will be superior, hands down, for hard aerobatics/3F. If no rapid engine transitions are indicated, the 32F is a great little motor.

2. Parts cost; you will need a piston, ring, and liner. A new con rod probably would be a good idea as well. And we haven't even discussed bearings yet. A new 32SX can be had for around $120. I would not be the least bit surprised to find that a piston/ring/liner for a 32F to be over half that amount, or more.

Bottom line; the 32SX is about as good & dependable an engine as you could ask for; and rebuilding those 32Fs could run into some serious change very quickly.

I have never been one to assume that just because something is newer it has to be better. But in this case...

Rebuild old technology??

Well that pretty much answers the question. I took the Rappy out today with a month old 32 SX on it and this cooler weather really makes it a screamer!!! Had to richen it up about five clicks and it was still pulling the thing straight up. I guess the old 32F's will make nice paperweights...
