This time of year, the choke should be wide open. I like to use an electric fuel pump by the tank to feed the mechanical pump. The mechanical pump acts like a regulator. I turn on the electric pump first before I start the engine. Tip; run the electric pump with the engine off and adjust your floats with a still motor. Try shooting ether in the air cleaner first before you do anything. If the car starts without pumping the carb, it is a fuel starvation problem.

Thanks for all the input! No pools of fuel. There's still fuel in the bowls. The acc squirters works just fine. The carb is a "divorced choke carb" but it's never been this hard to start before. It all began sometime during my tuning to get rid of my hesitation problem. (which got better) Everything should be close to "by the book" now but... It's hard to start even though I still have 5-7 psi to the carb when the engine been still for a cpl of hours. If I don't touch the gas pedal at all when I crank it it usually starts a bit faster. I'll check the fuel bowl levels once again! The levels are a bit high since I noticed a slight improvement with my hesitation problem when I raised the levels a bit. I'll check for vacuum leaks around the carb base & intake manifold. I'll change all the hosing from the tank to the carb. I'll rebuild the carb. I'll take it one step at the time & report any improvement to you for future troubleshooting. Pelle
