Craftsman 917.388220 Resurection

Another vote for Berryman’s B12. I have the same engine on a 200? Lawnboy walk behind. I haven't run it this yr, BUT .With some gas and a spray of carb cleaner aimed at the air cleaner, it will start 1st pull. That's as good as it needs to be for its role as a 3rd string weed wacker. Carbs aren't worth messing with. After mkt carbs are cheap.

I’d suggest Berryman’s B12 to dissolve any gum and gunk in the passageways and moving parts. MMO doesn’t have the solvency you need.

Be very careful on Tecumseh carbs with B12 chemtool, they have emulsion tube gaskets inside that I suspect will swell when exposed to b12 chemtool.

Was it puking gas out the Emulsion tube again?

No - it would appear that the float and needle valve are working. Unfortunately it's will only run for a second at most using starting fluid.

Possibly the float is too low - not getting enough fuel. Either that or something has gotten stuck in one of the jets.

You could try raising the float a bit. However its hard to figure out the right spot on the engine.

I took a look at this old Craftsman 22" push mower today. I am guessing that it hasn't run in ten years. It appears to have a Tecumseh 4.5 HP flathead.

I hit it with a shot of starting fluid, gave the rope a tug and it started. Encouraged by this I added fresh 90 Octane E0 to the bone dry tank and tried again. Unfortunately it would only run for a second until the starting fluid was consumed. The primer bulb didn't appear to be giving any resistance so I inspected the fuel lines and moved them around a bit. After a little while it started expelling all thue fuel via the red line shown in the image below. Are there any suggestions other than just replacing the carburetor? I neither need nor want this machine and it's not clear if I should invest any further time or money to get it running. Maybe someone would pay $20 for it as is.

It's a Husqvarna. So says the 917.
