case 611b running rough when warm

Anonymous-0 · Sep 15, 2008

I have a Case 611B that starts & runs for about 20-25 minutes and then it starts chugging like it is running out of fuel. If you pull the choke all the way out, it will idle smooth but has no power. Seems to have good spark. I replaced the coil earlier this year because it wouldn"t run at all once it got warmed up. Any help would be appreciated!

You most likely have a little piece of dirt floating around in your carburetor. Seems like the smallest speck of dirt on one of the needles will make them act like that.

Check the outlet at the gas tank. You may have some dirt that is blocking fuel flow. Might try blowing back through fuel line into tank.

Thanks I'll check that out. Sometimes these things can really baffle you.
