My son gave me a XL Automatic and I decided to get it running. Tired of using the SXL as a limb saw. I rebuilt the carburetor, replaced all fuel and oil lines including duck bills. It started up on the third or fourth pull. The problem is, the idle is erratic. when I pull the trigger, the RPM's will stay high for about 15 seconds and then idle down. The shaft does have a little side play but didn't seem excessive. The carburetor will hold 6psi vacuum. I looked the linkage over and all is free and clear and no binding. Any thoughts and suggestions? thanks

Anyone know where I can buy a throttle shaft for a tillotson HK-27B carb? With my luck the crank seals are probably junk too. I don't mind throwing a few parts at this saw to get it working.

You might be better off getting a Walbro or Zama carb & get rid of that little Tillotson carb,as they're a giant PITA to work on.The Tilly kits are quite pricey too.

Thanks for the advice! Yep, the kit for this carb was twenty bucks and change. I'll start looking for a different carb.

kb2: I have a HDC 65 & a Zama C2S. The HDC 65 holds at 10. Zama will need rebuilt. If interested, send me a PM. I have about 10 / 15 of the XL models. Can see what's on them, if you need a different one.
