Ms 440 rebuild

[Lumberwolf]

Going to rebuild a 440 soon out of all my spare bits. Is it worthwhile putting new piston rings and a carb kit in while I'm at it? It's just for a backup or to put a bigger bar on for felling so it'll hardly ever get used. Cheers

I overhauled a 440 a few years ago. If your taking it completely apart then yes I'd change the rings and while your at it, a small end bearing. Your going to need new gaskets as well.

As regards the carb kit, unless your having problems I wouldn't bother as this can be done anytime without too much hassle.

New piston and rings, new little end bearing, new crank bearings, new crank seals, new gaskets all round, rebuild the carb with a complete new kit. I see no sense not doing it all.
