Are you needing the carb or just that part of the carb?

i've cleaned the carb in my usc and have all the other pieces so i'm thinking i just need that part. however, we all know how old carbs are; sometimes they resist cleaning.
on the other hand if the carb you have is a runner i may be interested.

Jerry,
Its a Craftsman 3.7 with a Tillotson carb. I'll pull the carb and get you the numbers?

 

[jerrycmorrow]

Randy, Mine is a 917.353771 version of the 3.7. Didn't think it came with a tillotson but have been wrong before

One thing on the SDC is the main metering check valve can go bad and that thing don't come in the kits. Neither do the accell. pump diaphram of late.

When you drill the welsh plugs, drill them off center.

I'll have to loolk but, I may have one SDC leftover from my XL-101 binge.

Carl.

A lot of us are guilty of some kind of saw binge ( or maybe a tool binge ).

Its hard for the women to understand why we need 1 more of something we already have 2 or 3 of.

Yeah, but just look in a woman's closet. A man couldn't wear that many outfits in his lifetime.

thanks randy. does it look like this?

 

[watsonr]

Looks like this. Craftsman 3.7 with auto sharp.

Saw is low on compression. Nice shape, to bad the owner killed it. If this is what you looking for, its yours.
