Check the rubber O-ring seal around the needle valve, they had a lot of trouble with leaks around there. You can use a piece of fuel tubing to repair it in a pinch. A friend has 2 of them and they both gave him fits.

Everything else sounds about right. Are you running good fuel in it? Old fuel will make them run like crap. How's your pipe length? It should be in the neighborhood of 3-1/2" measuring straight back from the center of the plug and across to the weld or widest part of the pipe. On some pipes you can measure at the wrong place, I found that out with my Irwin quiet pipe.

No problem. It'd kind of hard to know what's going on over the Internet. Sometimes we need all of the info possible to help determine what's going on. Sometimes I ask too much possibly making people insulted but it's difficult not knowing what a person does or doesn't know. This was not pointed at you, I am sometimes the same way. BTW, what helped?
