well first i tried the needle at 4# seemed to run good but dead spot on the bottom..
so I moved to the 5# went for a ride to me it was runing good till I got on some rough stuff then the plug fouled..

Ok now does this make sence to anyone....
Now that I think about it I seem to have lots of problems when I practice on a mx track or I'm on bumpy ground is there something that could cause my bike to foul plugs because of bumps..

Did the pilot screw need to be turned back in a little when you switched to the richer clip?? To about 2 turns sounded OK. :)

The float level can increase with the shaking around and bouncing. Clark has suggested lowering it by 1mm which is a good idea.

Are you confident the accelerator pump has enough delay, starts squirting between 1/8 and 1/4 throttle. (talked about it before, I know)
Are any overflow tubes clogged?

Fouling the plug sucks. :D

I turned the screw to 2 turns out before I left.....
I'll have to check everything again..
It won't hurt to lower the float 1mm...
I'll try that also...
my slide is about a .5 inch open when it starts to squirt gas...
If everything seems good in the carb I'll move the clip back to 4# try that....
If I was to yz time my bike would that help It to burn the fuel better...
