Boiling carb bodies

[Nessism]

There is quite a lot of information in the internet about using Pinsol and it must work pretty well. I looked at a label a couple of weeks ago and saw something interesting. It comes in 2 'flavors'; original and lemon. One of the labels said it wasn't good for extended use on aluminum but the other label didn't mention it. In any case, I'll bet it would take a long time to do any damage.

What I decided to do this time around was disassemble them, wash them in soapy water, rinse them, give them a short bath in MEK (about an hour), and thoroughly rinse them. After that, I pressure-flushed all the passageways with a 50cc syringe and large IV line, which seemed to work really well. Then, I dried them with a shop-vac blower and took them to a tire shop and blew them out with compressed air. I would have no qualms about using one of them for a beer mug......if they would hold enough beer.

One last mention for you guys soaking carbs in MEK, Acetone, and (insert name of harsh chemical here), The CV carbs have rubber throttle shaft seals inside the carb body that are susceptible to chemical damage. Keep chemical soaking contact down to the minimum possible to clean the carbs.

Regarding boiling carbs in lemon juice or PineSol, I did this one time (using diluted lemon juice) and the carb bodies turned dark. Buyer beware.

Agreed with the darkening of the carbs. The PineSol will cause darkening. Use only degreasing solutions that are ALL METAL SAFE. It's one of the reasons I use Simple Green HD Pro. Never darkens the aluminum even if left standing for over night in a sonic cleaner.

I agree with that! That's why I kept the bath in MEK rather short. I'd never worked with MEK before but it doesn't seem nearly as nasty as the old Berryman's stuff.

Lemon soaking=dark, Pine-o-sol (Aus stuff)= Dark, Oven Cleaner=Dark. glass bead blasting the outside with fresh beads from a distance similar to painting is quiet impressive, just dont have that "gloss" new cast carbs have. Trial and error before i attack 2 sets of 33 Smoothbore Mikunis. Carbs taped up and only did outside and bowl.......

I've also done the bead blasting thing to brighten up a set of dingy looking carbs. Soda blasting is safer for that application so that's what I'm doing now. Add some new plating and your carbs will look like new afterwards...

Pinesol mixed 50 50 with water cleans carbs great when heated to 180 to 200F.

It works even better at the same temperatures in an ultrasonic cleaner.
