My MTD Yard Machine Y2500 starts fine and works with the choke partly closed. It also idles fine with the choke fully closed but stalls when I press on the throttle when the choke is fully closed.

Thanks for the response but I made a mistake in the request. It stalls when the choke I opened, not closed. Thanks for the response but I made a mistake in the request. It stalls when the choke I opened, not closed.

no worries,, if thats the case,, you need to turn the idle mixture screw in about a 1/4 turn, that should fix the problem,, if it doesn't,, pull the plug and see if its wet and black, if so put the idle screw back where it was and replace the plug , its not firing fast enough to burn all the fuel so its flooding itself out. no worries,, if thats the case,, you need to turn the idle mixture screw in about a 1/4 turn, that should fix the problem,, if it doesn't,, pull the plug and see if its wet and black, if so put the idle screw back where it was and replace the plug , its not firing fast enough to burn all the fuel so its flooding itself out.
