So I managed to score a vintage polished 2 deuce Sharp intake for my flathead this weekend. It's in pretty good shape with the exception of needing a couple stud holes tapped because there is no threads in them, but the guy did throw in a 3 Ford 94 carbs to seal the deal. My question is, what would be the best method to clean the carbs? What is a good solution to soak them in once they are disassembled? What would be the best way to tap the holes for the studs on the aluminum intake?
Are the stud holes really not tapped? I would think it is more they are stripped. If this is the case, the threads should be repaired with "Heli-Coils" or a similar thread repair method. You may want to take a close at the alternatives available. "Heli-Coils" are sort of a basic repair, and there are other alternatives available, such as "Keen-Certs", EZ-Loks" and others that may be better. If they are the carb mounting studs, you should have enough "meat" so you should be able to use the repair method of your choice. As to carb cleaner, I don't know what to tell ya'. The last stuff I bought at my FLAPS didn't work nearly as good as the stuff we used to be able to get. Myself, I've been considering buying an Ultra-sonic cleaner for this. The trouble, is, the size I would really like to have is kinda pricey. I saw a thread on here or the "Barn" where someone said they had good results using brake fluid as a carb cleaner. I have a hard time believing this, but you know what DOT-3 does to your paint job.
I clean carbs in a thrift store crock pot filled with Mean Green or Awesome cleaner from Dollar General. Works great, leave on high setting for 8 hrs.
I still just use the carb cleaner in the gallon can with the basket from the parts house. With those carbs you can probably soak a few parts at a time in the can. With bigger carbs I have been setting the carb body in a pan that I got from the Dollartree and pouring the cleaner in with it and then pouring it back in the can. Fresh cleaner seems to work fine but I think the complaint is that you don't do as many carbs in a batch of it as you used to be able to do before it didn't get the job done.
