I sold a 4.2 cubic inch chainsaw to my son-in-law cheap. In the 25 years I owned it, I never had to replace any carb parts. The only items I replaced was the sparkplug & the fuel pickup in the tank.

It is very clear too me that rubber products was made of a very high quality in the old days. I am sure the companies that produce any product now, use cheap as possible rubber because they save money. Also they make very good money fixing theitems they sell. Sure you can buy new rubber parts...and they are way over priced too.

That old saw runs great even on the standard pump fuel sold in Michigan. So I call it the GREAT RUBBER PRODUCT RIP-OFF. Capt,n
