Thanks for quick reply Dave! It's a stock type but new pump which is supposed to put out 5-6 psi. I'll get a guage on it soon to check.

Y'know, I think you nailed it on the crossover. I had been having some exhaust leakage into the adjoining cylinders through the gasket due to wrong (way too much rtv) install on my first rebuild. To eliminate that possibility and living in FL I decided to block off the x-overs. I do remember now reading some posts about slower warm up without the heat.

I'll go ahead and reset the floats anyway since it was running fine before with the out of box setting.

Thanks again.
