I’m trying to rebuild a stock carb off a 01 Softail that’s been sitting for 10yrs. I have it all apart and except for a bunch of dried sludge and vanish, it’s looks pretty good. I was able to clean most of it, but how do I clean the ports? The manual says not to use any caustic cleaner and suggests Simple Green and hot water, which does absolutely nothing. So how do I get the crap out of the ports? If paper towel lint is an issue, I’m sure a bunch of varnish debris is fatal. I’m ready to move forward with a rebuild kit and new jets, just need some expert advice.

I tried spray carb cleaner. Didn’t do a thing.

this is the after of a varnished carb, I was totally impressed. You can see the can in the background. Gunk.https://shop.advanceautoparts.com/p/...E&gclsrc=aw.ds

I got it. Put the carb in super hot water and spayed on Awsome cleaner from the 99 cent store. It’s safe to use, cost $.99 and everything just melted away. It worked so well, I’m going to try it on a gas tank.

glad pinching pennies worked out. A buddy of mine used oven cleaner on his HD motor, what a permanent mess he made, but he saved money and labor.
