Just recently I have noticed that right off of idel my motor kinda wants to die, like when I come to a stop, then take off, give it some throttle and it revs up nice once you get past that point. I droped from 55 piolet to 50 helped a little, this was never an issue, so I don't think the piolet is the cause. thanks

If you don't think it's related to jetting. Check the CDI.

Is that under the "how to check electrical" also what is a good replacement choice for CDI, I think mine is stock.

borrow a stock one from a friend if possible. try to make this possible cuz other than that you can buy another stock one or try a DYNA igntion , but those have alot of stories behind em. some love em some hate em some work some don't personally I have one and it works great but I have heard horror stories from others who's don't work at all. so really try to borrow a known good one. at least until you find out if it really is the CDI causing your problem.

check your spark plug gap. i run a smaller gap on the old electronics seem to work better.

I am at 18, same set up as always, I have changed nothing, well I switched to 110 instead of 3 gal 110 to 2 gal 91.

smaller gap and a iridiunm plug will help weak spark but don't fix no spark. I use an ngk iridium gapped @.018

i don't want to mislead you have you checked you vent tubes on you carb for any blockage? did you change your mix when you changed you gas? is your coil wire in good shape possibly you need to trim a little off to expose good new wire. check your grounding.
