This is a very worthwhile reminder. I had good luck with Sta-bil + running it with the fuel pump shut off until it stalled + a little marine fogging oil at the end. Sat for 4 years, ran the fuel pump and it fired right up. I've had the bowls off a few times since, am thankful to not have found any creeping crud in there.

I learned the hard way also. On one of my cars, I put it away during the winter, and discovered in spring time my needle and seats became so hardened they wouldn't hold the float level anymore. Also my mechanical fuel pump stopped working, and was filled with a powder form of gas. What I do now, I get 5 gallons of 110 vp race gas, run it through and put it away with that, no more problems.

Bump...

Got "bit" again. Found the secondary accel pump needle below the nozzle screw on one of the aluminum body carbs we dynoed in October has corroded in place.

I've sqirted brake cleaner in the passage from both directions, did the same with WD-40, blasted air from the metering block passage... still stuck. Guess I'll let it sit with more WD-40 in the passage hoping it'll free up.

My OPINION at this point is that an aluminum carb that is used with fuel that contains any alcohol should be completely disassembled if it's going to be sitting around for more than a few weeks.

Got a suggestion for something better to loosen that check needle?

Switched to E85 last year for the octane and price. After the winter weather ended the fun for the year, I drained the cell and ran a couple gallons of pump gas through the pump and lines and caught the return line fuel in a jug. Ran the gas out of the carb, then removed it and completely disassembled it and removed all traces of any fluid. I had the E85 in there all last summer with no corrosion in the naked aluminum fuel cell, and nothing in the carb. or Al fuel lines. Don't know if I'm stupid lucky or what,but I didn't see any of the horror stories some E85 users speak of.

PB Blaster is pretty aggressive. Or some kind of mild acid, like the stuff you clean nasty aluminum with to weld it. Blow gun from the metering block side of the carb body. Just be careful where it's aimed or cover the top with a towel.


If the results don't match the theory, change the theory.

So you didn’t even try to dump an 8 dollar bottle of stabilizer in to at least see if it would save you any grief?

Engine went from dyno back to stand. Carb was drained of 50/50 pump 93 E10 / leaded race fuel and put on shelf. Residual fuel in accel pump circuit corroded. Not sure where the bottle of stabilizer was supposed to used in this situation.

PB Blaster... yeah, ran out of it before this problem turned up. Give that a try next.

Brad - unheated garage? I wonder if that makes it worse. I usually just drain the carbs but I do not take them apart and I haven't had any issues. But I keep my shop at 65 degrees so maybe that helps?

Do you have access to an ultrasonic cleaner? They work great and can get solvent to reach to both sides of the needle to loosen it.

I put a dab of oil in the passage and use a steel pointed poker and pry in the slotted area and rock it back n forth with and then use compressed air on the inlet side on the main body face if needed........Rubber hammer to knock it loose if that doesn't work..........

Got an 87 ford box van I bought new, 48,000 original miles, I use for my work. 460 ci. Might sit 4-6 months or longer at a time, starts right up and runs fine (holly carb) but all this talk has got me worried a little. If it ain't broke I ain't touching it. Always used whatever was at the pump, leaded reg at first, now 10% corn.

Responses in no particular order...

Andy -> My garage leads directly into my basement / psuedo shop; carbs are stored there where it's climate controlled

Dominic -> If the PB Blaster soak doesn't free it up, mebbe I'll ship it to Hesperia for you to hammer on it

RTS -> Nope, no ultrasonic cleaner access of which I'm aware

WHITEDART -> Ummm... yeah, pretty much; the more crap I'm seeing in my carbs, the I less want to leave it to chance they'll be good the next time I want to run 'em
