Ya, I think I missed the gasket for the high speed nozzle. I wonder if I have that nozzel to far in? I didn't throw away the remainder of the carb kit so I can go back and put that in. Thanks for showing me that diagram, even though I have one too I over looked that, and the oriface plug. That's probly my problem what do you think?

Quite possibly has something to do with fuel flow and the tube and the holes that supply fuel and alignment. I know when parts of left out of a carb by mistake they usually don't run right.

Thankyou, I may have never figure this out. Of course I still have to do it and see, but yes, Makes sence to me. Thanks for your time. You were a big help, and I am feelling so much better like I have it fixed. I will write back tomorrow about noon Michigan time and tell you if it fixed it. Hopefully my carb gaskets will still be good. This is the third time for them, but they are new. really the only one I need to reuse is the float bowl gasket, and it's spungy. I will ad the boss gasket and make shure that the old one is out. I will pull the oriface plug and make shure its clean. I hope that comes out easy!

Bingo! I took the carb apart again and made a special tool to take out that orifice plug, ( ground a screw driver to the exact size to fit in there). Luckily that was clean. I did notice that the boss gasket was not in there. I figure it must be the washer in the kit that matches the color and material of the float bowl gasket. It's about 1/4 " thick too and makes contact to the orifice before the bowl gasket. That gasket completes the channel for the high speed nozzle and now it runs like it's bran new! I feel so good, like a kid at Christmas time! Thanks to you and this forum I have fixed my problem. What a great tool this site is! Thanks again, John. Yippee!
