149 Stalls

ColoradoCadet · #1 10-06-2011, 12:23 AM

I have a 149 that I purchased about a month ago. Starts well, but it is now stalling out after running a couple minutes. Didn't do it before, but does in now.

When it first did it I took the plug out and cleaned it; no help. Took the fuel line off and it seemed to have a good flow of fuel from the tank. Started it with the aid of starting fluid and after a lot of coaxing it ran fine. Now it is pretty consistent. Starts up like normal, then after a minute or two it just stalls out and won't restart.

Any recommendations would be appreciated. I would like to get it running so I can move it inside the garage before the first snow falls down in the lowlands here.

Thanks in advance.

As a suggestion, I would look at the Carb with gas flow delivery. Maybe something partially restricting the flow through the needle seat and/or a float issue.

Rig up a parallel "fuel tank". I use a mustard squeezer...you know, those flexible containers on the table with the long spout and a screw on top. Slip a new piece of fuel line on it with the other end feeding the carb and you've bypassed the filter/needle valve assy. You can run it this way for some minutes to determine if it's a fuel feed or carb issue (or electrical).

I know there's no vent in this arrangement, but with a small squeeze of the bottle every few min you can fill the carb bowl.

The best part is that it takes about 30 seconds to implement :-)

Thank you, I shall try the bottle (no pun intended) and then move on to the carb if that doesn't work. Chance of snow this weekend

Could be the coil but most likely running the carb bowl dry.

I'd check the tank for junk floating around in there. It can cut off fuel flow to the carb, then after a bit might take off and run fine, but will continue to cause you problems. Your 149 should have a screen on it that is attached to the shut off valve, it sticks up inside the tank and acts a strainer for larger pieces of trash inside the tank....your screen might be missing or rusted off, allowing rust flakes to block the flow of fuel.

If you do, in fact, have good fuel flow to the carb, you've just eliminated everything upstream, and it's time to rebuild the carb, which you should do anyway since you just bought the tractor and don't know the history.

I did not have a good flow of fuel! I had to blow into the tank very forcefully to get any flow going. It is a little rusty in there. (picture attached) I also found a piece of plastic floating in it. The filter was clean enough to allow fuel to pass, but it wasn't pretty. The oddest thing (to me) was to learn that the gas tank is only 2/3 the size it appears. 1/3 is blocked off. Why is that?

There is a baffle built inside the fuel tank. There is an area where fuel can get into that area.

This is the same thing that happened to my 149 last week.
Start and stop...
My fuel line was partially stopped up, if it sat for a while the gas would make its way to the carb. but after a few minutes of run time and that gas was burnt, there was not enough flow to keep it running.
Removed the tank, replaced the lines and added an inline filter, now all is well.
