Like the title said. If I hold throttle steady at say 2000rpm and take my foot off it idles for a second or two then reads dead lean and dies could someone point me in the right direction.

The Carb,

Thanks

Re: Converted to e85 now the carb is weird ...

What kind of fuel setup are you running? And just to clarify - you had your carburetor modified for E85, correct (not assuming anything, as I've actually seen this attempted before without conversion so I figured I'd ask)?

If you didn't completely recalibrate the carb for E85, you didn't "convert" to E85.
