Pressure building in tank

Do all the other suggestions for fuel heat. More than likely you are running rich at 90* + temp. Check your fuel pressure and float level. The open air cleaner sucking in 200* plus air is also not helping the AFR.

Yeah I'd be interested in going a different route for an air cleaner. Although it dyno'd more with that air cleaner than even an open carb. But the hood was off, wasn't sitting in traffic, etc..
