On my return I was pleased to see that the Odyssey held a charge. I added fresh fuel, sumped and started. The starter turned over nicely, at 300 rpm, but no fire. Repeatedly. I opened the cowl had a look and sniff---hmmm, no fuel odor. Would have expected to encounter a whiff of gas.
So I pulled cowl, and dropped one of the float bowls. Plenty of fuel spilled out. I was surprised to find that the floats were *adhering* to the bottom of the float bowl. In three months I guess the small amount of gas remaining in the float bowl had congealed; I live in a warm/hot place. As it happened I possessed the replacement floats, and this was a good reason to install them. I cleaned the interior of the bowl and the pins with a rag and WD-40, verified free movement of the new floats. Put it all back together and wham, within five seconds the engine roared back to life, just like it did in November. Whew,
