Okay! So, I have some answers as to what has been done so far with the bike.
According to the mechanics (I had actually had two mechanics work on it):
-The oil had been initially changed after the engine flooded.
-Carbs were drained, but not entirely sure about the fuel lines (at least the second mechanic hadn't).
-Instead of seafoam, a product similar to Ajax was used... in the cylinder head / compartment-- which was to rescuff up the cylinder wall to reseat the ring.
-There had been low compression in one of the cylinders and after the Ajax procedure, the compression returned / increased.
-There had been a valve adjustment as well.
-With all of this done, the bike actually did run for a little bit for the first mechanic... but it did not run great; it idled high and didn't run smoothly at all (I think he had said it would surge, or didn't have any power when he tried to accelerate).
-I went to pick it up and drive it home, but when he got it started and it ran for a few minutes... but then it died and he couldn't get the bike started up again.
-The second mechanic had no luck because one of the keys went missing and the key he used worked in the ignition with some wiggling, but wouldn't open the gas tank - it started to bend- and so he couldn't change the gas.
The key was the kicker... and that's why he gave up... and I had forgotten about it...
Guess there is a bit more than just the float sticking. But the float was what started the giant snowball in the first place. Then it sitting and not getting any attention in between efforts... and now it's just a sad story.
So, now that you "know" what went wrong and what has been done to the bike... is it fixable? Or should I part the bike out? (The seat's great, the covers, the tank, the pegs...etc. are still in great shape.)
