Eythenol scum

[webbcraft2150]

Left gas in my Xj 550 too long. Have dreaded ethanol scum everywhere. What will dissolve this stuff? Been using ultrasonic cleaner with Zep degreaser and Berrymans. Pilot jets are welded in now.

Carb Cleaner

I like Berryman's for said purpose.

How did the bike sit? I leave my bikes for 4-5 months during winter without draining the fuel bowls and have not had problems (yet).

webbcraft, at this point I suggest you remove all internal pieces of carbs as possible. Then, since I presume you have an ultrasonic cleaner, buy a jug of the REAL Pine-Sol, no generic. Put that, full strength in the ultra-sonic cleaner along with carbs and all the associated pieces in the ultra-sonic for a period of time. Remove and wash all pieces with hot water. This should be of help as several others here have done this with excellent results.

Bike was parked about 2 months. I kick myself for not taking it out and running it. Carbs were in a box when I got and have a ton of time getting it going. Was a strong runner. New paint and seat and hours polishing neglected chrome and aluminum. Was getting it ready for sale with 80 degree days here. It’s a fun bike but too small for me. Need to see if I can extract stuck pilot jets now then try the pine sol trick. It was a “free” bike, if there is such a thing.😂

Two Months- Wow!

Yikes! I'm shocked it could gum up in 2 months. I've awakened all my bikes this year, even though it's still snowing in Detroit. I didn't have any casualties.

Hopefully that Pine-sol will solve your woes.

Here in Can'taffordya I've watched the gas turn colors in a tank within a month! You REALLY need to be aware of the crap they call gas now. Use the B12 Chemtool to clean the carbs. I have a plastic tank for tuning, so I would put strait B12 in it, hook it up to the carbs, try and start for about two 30 second bursts, then let it soak for two hours before trying again.

Ok. Pinesol and ultrasonic did a good job. Stuck pilot jets came out with #1 screw extractor, 5/64 drill bit and some heat. Sweating bullets on that job. Now, new pilot jets, enricher boots, triple clean and reassemble. Then put carbs back, dial em in and put a for sale sign on it😅

The carbs were so gummed up the slides would not move.

Good to hear the Pinesol resolved your issue.

I'm not convinced the pine sol cleaned em out good enough. The scum the gas left is some tenacious stuff. I have some skin dissolving, old school berrymans I'm going to soak em in for a short time. Then blow em out with spray cleaner and air. Have to round up the pilot jets.

I'm sure you know this already, but don't let the throttle shaft seals soak in the Berrymans or they may leak afterwards.

Agree......those O-rings and others internally don't agree with a lot of cleaners, specially Berrymans.

Yamalube works great and won't hurt the carburetors. It's especially good with a heated ultrasonic cleaner.

That was me when I got tired of playing with homebrews and hand tools with elbow grease and decided to at least try the stuff designed to do the job.

Pinesol is less expensive but I don't like the way it smells and makes everything else smell too.
