I'd be interested to see how that e-85 carb works out for you. I see you are from Aurora. I'm at 225 and iliff. I have had the electric choke set all over the place and I do have a spacer on it too. Once it warms up the plugs look clean and it runs pretty good. No stumble or pinging anymore; it's the starting/idle circuit that is killing me. If it doesn't start up easily at first then it quickly fuel fouls the plugs and then won't start without cleaning or replacing the plugs. That is why I'm wondering of the slop in the butterfly shaft is causing problems with the idle circuit transfer slots being exposed at varying amounts. I'm running ngk xr5 plugs. You guys don't think a 950 would be too much for my mild build?
