Default what happens when an engine sits up (suspect ethanol)

I suspect this is ethanol gas, but supposedly this bike had been sitting for a year before I bought it (prior owner had it for 6 months, and was told it had been sitting that long before he bought it).

Gas tank, fuel line, and carb were full of basically dark brown goop with the consistency of hot fudge. Got the tank flushed out with clean gas, and boiled the gas line, carb, and petcock in lemon juice for about 30 min. Still had to use a brush to get the carb clean. Fired right off but dang at the crud and goop.

Petcock was still clogged up and no amount of boiling, air, or chemicals would budge the clog (in hindsight might have tried muriatic acid but pretty sure that would have eaten the petcock).

Anyhow, ground the rivets off to open the petcock and found this........ took an eyeglass screwdriver and dug the stuff out. Again, this is after boiling for close to an hour. Of course, when I tried to drill the rivets out to tap and put back together with screws I busted one of the ears off. Have another petcock lined up from tplane.....

Anyhow, if you're gonna leave your bike setting up, SHUT THE PETCOCK OFF and run it dry, or better yet, DRAIN THE TANK, and then run the machine dry.

If at all possible, don't buy gas with ethanol. I buy ethanol free here AND use stabil or startron.

More pics of goop coming out of gas line and on float needle.

The third pic is the crap that I got out of the old Honda generator's gas tank. Same thing; been sitting for years. Stuff in the bottom of the tank was literally 1/4-1/2 thick. Mineral spirits wouldn't touch it. Finally poured muriatic acid and water in, and tumbled the tank with a chain in there. Stuff still wouldn't come out. Finally did muriatic acid again and then stuck the power washer down in there. Stuff came off in 1/2 dollar size chunks 1/4 inch thick.

Don't leave gas in your stuff for extended periods!

Don't think you want to try to smoke that rich.......

Gawd this crap stinks too! Basfnb had to use gas to get it off his hands Saturday. I used gojo and a scouring pad and can still smell it on my hands.

That ethanol is nasty stuff. Did the carbs on my bro-in-laws V-star after it sat for years with it in the carbs. It pretty much started desolving the brass inside the carb. Plus it looked like there was moss or something growing in there. Everything had to be replaced.
