1872 wouldn't start

[Gary C]

Wouldn't you know, just when we are suppose to get a major storm, the tractor that always started and ran good, didn't want to start.
I had been blowing in the gas tank before every start and it would start right up, not this time. I was going to remove the fuel line and check for fuel flow. It has around 1/4 tank on the gauge. I filled the tank up and used my paddle blower . When I finished I gave the 1872 a crank, and it started right up. Looks like a fuel pump may be needed.
It was 9 degrees when I went out, it's 2 degrees now. Too freaking cold to work on it now. As long as it'll run by keeping the tank fuller, I may just make it through until it gets warmer. Just in case we get some warmer weather, I ordered a new fuel pump. Had the same problem a couple of years ago with an 782 , middle of the winter, and colder than blazes and it also needed the fuel pump replaced. If I can make it through the winter, I'll give it a good tear down and cleaning come spring. I remembered it being tricky getting at the mount bolts on the 782. So removing the tins would make it easier.

On an 82 series, as long as you are on a flat, keeping the tank above a 1/4 tank will be enough to allow enough fuel to flow without the fuel pump. Hopefully it doesn't spew fuel into the crankcase.

I'll keep an Eye on the oil level and give it a good smell each time. I'm sure I'll be replacing that pump soon, even though I hate working in the cold, things like that bother me. If I remember correctly when I replaced the fuel pump on the 782, I used socket head cap screws, they stay on the Allen sockets really good to install the mount bolts without pulling too many of the engine tins.

Just bypass the pump so you don't need to worry about it leaking into the sump.

True Story! I have 2182 and the fuel pump went bad last winter. It was able to run at 3/4 throttle with the snow blower all winter as long as the tank was at least 1/4 tank. It was a little difficult to start without the pump. That pump is buried in a tractor with a sims cab. Took a whole day to get to that pump! I relocated it from under the seat, to under the hood if it goes out again.

Spndncash, sounds like maybe yours was pumping a little because on a 2182 the fuel tank is under the seat lower than the carb is. On the 82 series machines the fuel tank is under the hood and only the bottom 1/4 of the tank is lower than the carb. As long as you keep the fuel level above the carb it will gravity drain into it.

Although even that can be questionable if the pump fails in an obstructive way.

It would only start on ether, no clicky noise at all from the pump. It may have just been very weak or the diaphragm ruptured. The amount of work to get to the fuel pump with the cab on forced me to wait until spring to change it. Removing the fuel line from the carb - the gas would barely drip out with the key on, the engine hunted terribly at all RPM's. Still better than shoveling snow.

Fill it up and bypass the pump completely.

Looks like spendcash has already fixed his problem last spring.
