Question Tecumseh on a Troy built chipper

There I was moving right along when back firing and loss of power hit. Had to close off the choke to keep it runing.

Today I replaced the spark plug, blew out the fuel line, added fresh gas, removed and cleaned the carb. Air filter is new as well.

Just fired it up and it surges and still needs to be chocked to run. Wont run too long then dies.

I'm at a loss. I can repair commercial AC but this little one has got me.

Tecumseh hm100 159383P (c)
Family W7pxs.3582BA
Displacement 358
D.O.M. 9015 D

Thanks in advance

You said you cleaned the carb. Did you clean the bolt that holds the float bowl on?? I believe it should have 3 holes in it & one is really hard to see, especially if it's plugged. Look for a small hole below the top part of the threads, (I use the wire from a parts tag to run thru it) Clean it out & you should be running again. Good luck, Roger

I agree with hopkinsr2, I use the wire from a twist tie. Have a good one. Geo

If you work on commercial AC, then you probably have a set of torch tip cleaners. If so, there is a tiny cleaner in the set that works perfectly for cleaning out these tiny holes.

Cleaned the bowl bolt, No joy.

The larger 2 holes were clean. unsure of the top hole. I didnt get anything out of it but it got reamed any way.

Still needs to be choked to run even for the shortest of time.

Still a carb problem...you may need to remove and clean the carb in a bath type cleaner and rebuild it...or buy a new carb (probably in the $45 range) and install.

We failed to mention that besides the 3 holes in the bowl bolt(main jet) there is also one that runs through the center, so make sure junk is not in there also before you take it all apart. Have a good one. Geo

Thanks fellas.
I did get that center hole clean too.
There is not much to rebuild there is there? After soaking 1/2 hr to running, right?

Thanks again
Ed

I think the hole Geogrub is talking about is the one that takes a turn off to the side of the main pedestal that supplies the low speed circuit (does that sound right Geo?? ) Soak the carb in a cleaner & run a small wire thru this hole (it's really hard to find, inside the center post, under a drill plug & camofloged in the threads inside the hole ) A piece of a parts tag wire with a 90 degree bend 3/16 long will clean it out. If this is as clear as mud, let me know & we'll explain more. You'll need compressed air, a bath type carb cleaner & also a spray cleaner. Good Luck, Roger

There is nothing like the sound of success. Have a good one. Geo
