Hello porshman

Yes there is a gasket/diaphragm set that you can order for the carburetor,. It depends on who manufactured your carburetor. I fit is a Tillotson it is part number 957-150-100. If it is a Walbro it is part number 957-151-180.

Hope this helps,

You have to open up the whole machine and check the piston. most likely the piston and the piston rings are damaged

Hi Steve,

The Starter housing is item #112 on page C of the parts diagrams. The Starter Housing is part #394-112-621. You can also order the starter as a complete assembly. The starter assembly is part #394-112-642. Both parts are available from http://www.ereplacementparts.com.

Good luck with your repair!

It doesn't sound like the ignition coil to me. It might be a problem with the exhaust being plugged up. You might want to remove the muffler and clean it out. Sometimes those mufflers can get a lot of stuff in there which will restrict airflow. If that's not the problem, you should probably check the compression against your other saw. If they're different you may have to replace the cylinder and rings like you did on the other saw.

Hi, just went to Home Depot, they have a couple used ones, they will sell me a non-starting unit for $200... is this a good deal? I checked the compression in the store >120psi, so that looks fine. The ignition seemed weak as well, I pulled the plug out and turned out the lights while pulling starter, did not see any spark. But then I touched the plug with my hand and got a good tingle when starting, so not sure if the coil is the issue. I can certainly try the "clean the muffler" routine, but I get the impression that these units are hard to start and then start to go "bad"... They take a lot of punishment, concrete dust is nasty stuff.

Is $200 too much to pay for this, assuming I might have to put parts in? I have a pretty big job coming up and if I could get it at this price, add a $100 blade I might be in good shape.

thanks!!!
