I have had three of this body style carburetor come through with this passage clogged

Gas Font Auto part Machine Cylinder


I have found that there is a small jet internally behind this ball seal
Gas Font Auto part Fashion accessory Metal


Getting to it was a destructive [process. Is there anyone who knows how to get to this jet to clean it NON destructively? I have soaked these things in degreaser in a heated ultrasonic cleaner for hours. I have soaked them in carburetor cleaner (both Chem Dip and carburetor cleaner sprayed out of a can) in the ultrasonic cleaner for hours. NOTHING breaks the gunk up so that I can get spray or air through it. Surely there HAS top be SOME way to clean these without having to replace the bodies!?

Any help, advice, tips or tricks would be GREATLY appreciated here! Thanks.

If I can't clear the ports using a welding tip cleaning wire, carb cleaner, and an air blower, I fire up my steam cleaner. I use that steam cleaner for everything around the shop and house. It's one of the best tool investments I've made. However, ethanol gas may have not only gummed up the ports with fuel varnish, they may actually be corroded shut with metal oxides too. I have a small set of micro bits that are good for clearing corroded jets but they won't bend around corners. If a replacement carb is less than $20 I usually just toss the old one in the spare parts bin and order a new one as the Welch plugs are going to cost half that much unless you have enough need for them to buy them in bulk.

If I could GET to this jet, that's exactly what I always do as well. That's the problem, though. I can't get at it. I'm not sure what a steam cleaner is, but maybe similar to an ultrasonic cleaner? I have bought those cheap aftermarket carburetors in the past, but I would up having to swap jets from the original carburetors because the new ones weren't right or I'd have to modify something to get it to work... it was just more a hassle and waste of time than if I rebuilt the original carburetor to begin with. And I do buy the welch plugs (and bowl gaskets and float needles and... ) in bulk :) I appreciate it, though.

This is the steam cleaner I have.


I use it to clean the bathroom, kitchen, carpets, beds, stove, dishwasher, windows, shop floor, and just about any greasy or dirty small engine, part, or tool that's not worth getting out the pressure washer for. The only down side is it takes about 20 minutes to heat up.

I also have an old Waterpik tooth cleaner that comes in handy for cleaning stuff at times.

Oh... ok... and that's good on carburetors? I'll have to check that out.

You can get cheaper versions for as little as $35. You do have to be careful of melting stuff like linoleum and cheap plastic but since even plastic carbs are designed to be attached to hot engines I've not had any problems melting them. A steam cleaner makes short work out of cleaning the grease and dirt off of a carburetor before you remove it.
