Uploader/Pump Problem...?

Paul Kassander said:
If it runs fine till you let off the trigger it is your unloader that is the problem (not going into bypass). If it dies when you pull the trigger then the motor is the issue and it could be a valve job (can't handle a load). If it runs fine for a while and dies randomly it may be the fuel cap creating a vacuum in the tank.

Great information Paul, copied and put this into my Trouble Shooting file. Thanks

If there is junk in the tank it'll take a minute to suck up to the screen. Just the slightest fuel loss under that load will kill a motor. After the motor stops the carb has a chance to fill back up. Then u crank it again and the trash sucks back up and repeats!
I would also unhook it from any accessories like a downstreamer or burner and then try again to eliminate everything.
And u can unhook the hose from the pump to the unloader and put a quick connect on it with a
nozzle and pressure gauge then see what happens. If the motor dies its probably fuel if it doesn't then u know its the unloader.

Another for my trouble shooting file. Good info to have. Thanks for posting your thoughts.
 
I'm glad you went with an electric start! This would be miserable without. It sounds like you've got a good array of diagnosis here and you video really helps!
It sounds to me like a fuel volume problem. When under load, the engine isn't getting enough. Follow the fuel from tank to line, to filter to pump (if you have one) to carb to valve to cylinder to valve and exhaust. Fiddle with governor and springs. Get ready to learn a lot about your machine! You can even try pulling the plug to your oil censor. If that were the problem, it would likely die more randomly and be hard to restart, but it's good to rule out and learn about.
 
I had a similar problem last year, it turned out to be the spark plugs and air filter.

I changed them out and it is still running great! Cheap things to try out.
 
We've ran into the same thing.. had to pump the wand trigger untill the motor got past the choking, then it would run fine. Did complete maintenance on the motor and it went away.
 
Update!

Thankfully, it was just a fuel issue!!!

I started out with spraying down the carb with an entire can of Berryman's B-12 Chemtool and replacing the air filter. I ran it for about a 1/2 hour or so and it's running GREAT!!!

I went on to change the motor oil and pump oil, but not the spark plug. The spark plug boot was beginning to disintegrate, so I decided to leave it alone until I can find a replacement wire.

I did nothing to the gas tank or cap, either.


This definitely was a wake-up call for me to consider the importance of regular maintenance on the machine!



Thanks to all that posted!!!
:yes2:
 
So I'm gonna say u had water in the fuuel if u left it in the rain! Rain got in tank and then in carb. When you took the bowl off u drained the water out of it.
Id replace the fuel cap if this is the case. I also use "seafoam" in my gas on a regular basis to keep my fuel system clean and free of water.
 
Jim you don't need a wire. That cap has what looks like a sheet metal screw inside that attaches it to the end of the wire.
