I think some engine react very different when run without a muffler. I took the muffler of my MB290 leaf blower to use on another MB290 on my test stand. Putting a muffler on the engine on test stand helped the idle on that one a lot. But my leaf blower now will not shut off and I need to choke it to kill it. Before it would idle lower than you could imagine. Bottom line...I think different engines can react very strange when removing the muffler!! Capt,n
That's what I was trying to say a few posts back when the guys was struggling with run problems without a muffler... He didn't get it so I gave up.
