They can be made into good runners, but it takes a lot of work.
I would love to help you Woodrow, but the importer I deal with cannot get them anymore since ALCO bought out Solo. If I could source them I'd source you one or sell you mine. If I was you I'd talk to M/Mind, he can get the 665's (same saw) and then source an OEM 681 piston/cylinder for it. The 681 cylinder is better than the 7900 cylinder for sure. Grab one before they dry up, good saws.CR888, interested in selling your 681?
i was told the 603 in stock form is not impressive. runs alot better with port work
What the 690 and 603 suffer from though is a bottleneck at the carb/filter- the filter is too small for the displacement of the engine and plugs up fairly quick.
Incidentally anyone have a 690 piston they would part with?
Is it still around?
Nate?Nope.
I think he may of sold the strongest stock light use 681 I every seen too. If he hasnt it is for sale on CR. $800
Come to think of it I think someone that buys and sells bought it that is a member here. So you might see it for resell.
I want one a demMy ears are burning. Lol. Y'all talking bout this one. View attachment 65933
