Carburetor cleaning?

[KE4AVB]

Thanks guys! That give me some insight! I thought it was primarily me not doing a good job on cleaning carbs! Ke4avb does have an interesting fix!? Course, I do not have any mini drill bits for this purpose or I might try it cause that's what's happening! It is easier to throw on a new carb though...that's always worked for me so far. Time is money and customer pays for the carb anyway.

You can pickup an oxy/ace tip cleaner drill set at your local welding supply store. The one I have has most of the micro bits for cleaning my torch tips plus it is a miniature hand drill with its own storage compartment. I like it a lot better than those wire type cleaners.

One tends to forget that engine requiring choke to run (lean on gas) can be result of too much air getting into intake area.
I've found couple that had leaking (air) welch plugs. I place a sealer around the welch plugs during testing if carb acts lean on gas. I very rarely pop out a welch plug (for cleaning passages with tag wire, small bits or torch tip cleaners, compressed air) unless it's a last resort.

I've also installed replacement carbs on rough running engines and engine still acted the same.

#/letter bits and tip cleaners can be found at HF cheap. has anyone done the 24hr pine sol dunk? ive seen a carb(motorcycle) spotless on a bench many many years ago and the fella told me when i asked him what he uses/has. he says pine sol, small plastic dollar store container. this thing was spotless

Also too much cleaning air pressure will cause a welch plug to start leaking or pop out a welch plug and it not get noticed and carb will lean out even more. (air leak)

Hey, I'll agree with you, Arkie!
I had a Briggs vert on a typical Craftsman yard tractor that was running lean and was missing the welch plug on the side of the Walbro carb. Put one in, and it ran perfectly.
