I have heard (on another site) that giving the carbs a good spray soaking in PB blaster after dissassembly was a good way to get all the little pasages ready for manual cleaning. Isn't BP a little rough on some metals.

Are there other products that work better than the usual autoparts carb dip in a can? Carbs are far from my skill set.

While im not sure of the exact chemical makeup of PB Blaster, it's not meant to be a cleaner. It's a penetrating oil/lubricant.
I doubt it would have anything other than very little if any effect on varnished gasoline and sediment trapped in the carbs. Varnish is nasty, stubborn stuff.

I wouldn't waste a good can of PB on it. Simply break em down and soak em for 24 hours each (body and bowl both), rinse with warm water, spray all passages with carburetor cleaner (wear safety goggles...those passages sometimes turn right around back to your face...believe me when I tell you carb cleaner in the eye is exquisitely painful) and watch to see that the spray coming out is even and a clean spray (nice fan type pattern) and install your new Orings. You can also use a strand of copper wire (softer than brass, harder than varnish/grime) to poke through your jets, emulsion tube, choke pickup etc. Reassemble once you're satisfied and bobs your mothers brother.
 
That's pretty much what I told the guy.. PB is great for some things... Not this.
 
If the slides or something is stuck it works great !! Just not as a cleaner !
 
Are there other options for cleaners that will work better than the carb dip. I kinda lost faith in carb dip when the EPA made them change the formula.

I also heard that heating the dip solution works well, but that just sounds all kinds of Darwin award dangerous.

Berrymans works great...maybe not he "California" blend, but it gets them super clean for me.
 
Berrymans stillworks good and now our local Walmart sells it. 18.00 a gallon
 
I believe some people put their carbs in ultra sonic cleaners if they are fortunate enough to have one.
 
Any carb dip is fine, it just takes longer with the new formulas. The old stuff, if you forgot about it, you wouldn't have a carb the next day. You can also add chemicals to it if you are feeling a little adventurous. A few ounces of battery acid will help make it more corrosive and give it that retro feeling.
 
I still love lacquer thinners. It has always worked for me & is cheaper than most so called carb cleaners.
 
Wow! What are the cons to using paint thinner over carb dip? Like, could I use mineral spirits or turpentine, or does it have to be lacquer thinner?
 
From my research alot of parts washers use or used mineral spirits blends.

Seems like there are quite a few different parts washing solvents. Just be carefull to check out if they are aluminum friendly. Or just don't let them soak very long. Varisol (mineral spirit) was used alot for parts washing but not really anymore since the changes to the Health and Regulatory guidelines on the product.


I'd like to try this: http://partswashers-pumps.graymills...gradeable-alkaline-aqueous-cleaners/item-1500


Carried by my local graingers. It comes in 25# containers so It would probably last me indefinately. Cost is right at $100. Water soluble with rust inhibitors and biodegradable which is really nice.

Could do a lot of carbs and other misc parts in my 5 gal restaurant table top portable steam table! :D

Carb dip is far more powerful than common parts washing solvents (like mineral spirits). There is no need to heat it or add additional chemicals. If your batch is old and slow to breakdown the varnish, get a fresh bucket.

Lacquer thinner is way too harsh for carbs and could damage the throttle shaft seals, plus the stuff is bad for your lungs and skin. Best to stay with the proper carb dip product for cleaning carbs.
