[Spridgets] Won't Idle

[GUY DAY]

Michael, you have had suggestions of:-Float adjustmentFuel PressureIdle screw adjustmentSemi blocked or blocked lines (add filters)Vacuum leaks
Just to round things off I'll add ignition timing.Dashpot oil
Clogged up poppet valve
As it was running after you cleared the fuel lines last time and the pump sounds to be running at all times it raises the question of  where is all that pumped fuel going to?  This may suggest a problem with the float operated shut off valve. Were fuel lines blocked the pump would stop running as it would be up to pressure.   It is obviously something that has happened fairly quickly as it is presumed it happened during the journey and it was ticking over OK (albeit with the choke on) when you left the house.  As it runs OK at higher revs this may suggest it is NOT a blockage problem.

 What happens when you 'idle it up' (adjust idle screw)?  Perhaps it's just set too low to idle.
What psi range does the pump run?  1.5 to 3.5 is good for these carbs, right.
Chance of rust/junk in fuel lines, getting into the carb & jets?
No vacuum leaks...right?

     Took the Bugeye out to run an errand tonight.  Could not get it to idle. As soon as I took my foot off the gas it would die.  I recently had a problem with the ethanol in the gas plugging up the fuel system after leaving it sit in the garage for a few months without starting it.  I installed a new Facet fuel pump, but I can hear the new pump going constantly behind me like the tank is almost empty, but according to the fuel gauge it had at least a 1/4 tank left.  As long as I kept my foot in it and did not stop anywhere, it ran like a scalded cat.  That new 1275 that I installed a few thousand miles ago is finally breaking in.  I was going to replace the fuel tank. (I have a new one ready to paint and install), but I got it running by draining the old ethanol laced gas and filling the tank with 100 octane ethanol free gas.  I thought I cleaned the fuel system out of the ethanol.  It ran great for a while. It did die a couple of times, but started right up again and would idle, now I have to keep revving the throttle at the stop light to keep it running.  I hate this Kalifornia gas.Mike MacLean60 Sprite56 BN2
