... especially with ethanol blend fuel. I pulled one of mine apart that I figured was ready to bolt back on and run, only to find a good bit of "stuff" had built up in the fuel bowls. The accelerator pumps were even worse, with the pump springs having corroded along with the build-up of "stuff".

Fair warning! hammer

does carb or bowl material make a difference in how the carb is affected?

Yea I had to rebuild a 6 month old carb that sat with ethanol in it for the same amount of time.

Not sure, but these are aluminum bowls FWIW.

Brad..You see a lot of that around here in small engines like lawnmowers. People are too cheap to spend a few cents more for better gas. FWIW,I just had my 1150 Dominator gone thru. Its only had race fuel in it and it looked pretty good.

I've seen plenty of scary carbs that had nothing but race gas in them.
Some of those fuels have some funky additives, and they can leave nasty build ups on the carb internals if left in too long.

Best bet is to pull the bowls and blow everything out when you put the car away.

Us pump gas street/strip guys learned this long ago....That "stuff" is nasty...

My lawnmower gets run dry at the end of the mowing season, plus fuel stabilizer in whatever is left in the tank. My 2-stroke weed trimmer gets straight 93 premix without ethanol.

The subject carb had been drained, but some fuel must have unknowingly remained in the bowls and accelerator pumps.

I can't wait to see what my Mallory fuel pump looks like after having sat with 93 E10 in the fuel system for so long. puke

Ahhhhh the dreaded white powder that actually creates a pitting effect on the inner carb parts. I drain em, disassemble em, WD 40 em and then store em for the off season beer

Another friendly reminder.

I was having carb issues this year and going on my 3rd season since my switch-over to alcohol. I go through my carb usually twice a season giving it a good cleaning and the usual maintenance but neglected removing and checking my floats. When it was suggested to me this year I ordered new ones and when I switched them out I checked them on my shops gram scale. You wouldn't believe how much the old ones weighed compared the the new ones from absorption. All appears to be well now.

I haven't had this issue but my Son has to take the top off his fuel regulator anytime the car has sat over 4 weeks and give it a good spray cleaning or it will stick 'wide open"

Yep. down

Even after scrubbing them down last night and hitting the corroded surface w/ a Scotch Brite pots & pans sponge, I'm not sure the surface is smooth enough for the rubber valve that acts as the accelerator pump one-way valve to seal properly now. frowwn

Yes. Aluminum in particular is a fairly unstable material. You can anodize the heck out of it but eventually Entropy takes over. Add harsh chemicals such as say Oxygen and the process speeds up. Same thing for plated steel parts, exposure to oxidants takes its toll. The only way to know whats actually in that 'pump gas' is to pay to have it tested yourself. But don't publish the results or Big Oil will come after you. Alcohols can be aggressive, that's why they make more power.

So nobody runs something like Stabil 360 for ethanol? Does that not work for this junky fuel?

I know some motorcycle folks who were going to try that, but never heard if it was working as advertised. I know carbureted bikes were getting killed by ethanol in pump gas when left to sit around too long.

I ask because I run that in small power equipment and don't have any issues. At least so far.
