Thanx for all the great info mates - much appreciated!

On the topic of 4A032 storage and removing fuel from float bowl to avoid carb float swelling - what do you all think about evacuating residual fuel from carb/float bowl using a Mity-vac or similar suction device (following running majority of fuel out of engine)?

Thanx guys and I apologize for going into "whine" mode on my earlier post. I had a lot of pride in my machine as compared to neighbors' Chinese imports and it let me down terribly during Irene. Even with that, I'm still trying to get it running reliably and sonuvab#@%& won't cooperate. Really...

Understand the ethanol sensitivity issue but if that is in fact my problem, I'm absolutely amazed that the swelling carb float occurred and incapacitated the engine in a period of less than four days of fuel exposure. If a period of less than four days' exposure to fuel queers the carb, how can...

Thanx Peter. I disassembled the carb today and it appeared to me the float was sticking on the side of the float bowl. I'll reassemble and give the current carb another try.

Thanx for your follow-up and I will try the gravity feed just to eliminate fuel delivery as a cause. FWIW, when I removed carb today I found intake manifold dry as a bone despite probably 20+ pulls. Does the float sticking problem always result in a flooded engine or can it also produce a fuel...

Thanx fro the tip. I can see strong fuel pump output when using the priming lever (with pump to carb fuel line disconnectd)

I'll keep the story short and just say I concluded that I needed a new carb for my 4AO32 powered genset. Got a new carb in from Saturn and bam! - the engine starts first pull (repetitively) and runs like a dream ....... for 2 days. Then back to the no start doldrums. The engine does respond...
