10% Ethanol will not start……no fire??
[1] E fuel is hygroscopic & absorbs water, which being heavier than the fuel will sit in the bottom of the fuel bowl. So whatever is at the bottom of the bowls goes through the jets first & you maybe pumping water, not fuel into the engine for a first start.
[2] Spark. Reminds me of the song, the 'Great pretender'. I had a coil fail. It produced spark. But the car would not start. Replaced every ign component...except the coil. But it had spark....so could not be the coil, correct?
In desperation, I replaced the coil & the engine fired up. Testing for spark in clear air is not the same as under the compressed air load in the chamber. Also, a yellow-ish spark is weak, blue spark is strong.
