Customer Question

I just purchased a 2011 toro power clear 621 r off craiglist. The problem I'm having with it is after I start it and it runs for a couple minutes the engine starts to surge. Checking online says its probably running lean. I dont see any carb adjustments so help with this would be much appreciated. Thanks, Mike

Your center jet in the carburetor could be partially blocked , once the auger is engaged does the surging stop ?

Expert:  Briggs-Fan replied 1 year ago.

If you can , clamp the fuel line , and remove the bolt in the bettor of the carburetor bowl, that bolt has some hole in it . 2 through the sides and one where it screws in , clean it with a wire and spray it out with carburetors cleaner. You may need to remove the carburetor and spray out the ports etc as well

No it does not stop when the auger is rotating. I cleaned all the ports in the carb with card cleaner. There are no holes in that bolt there is a jet that runs up the center of the carb that is visible by looking up from the bottom.

Did you spray that jet out, that's the main jet .
