1984 Work Horse GT-1600 REFRESH

[Lee1977 6,664]

The way to go is electric pump  I have pump connected to the R lug on the switch of my 520 it had nothing connected to it.  The ground wire from the pump is connected to a toggle switch on the dash the other side is connected to ground.

My 20 Onan floods real easy and I never knew if it was getting gas or if it was flooded, electric pump made it easy to start.

The starting procedure is. turn on the switch let the pump hit 3 or 4 times turn to start come up with the choke and right back down and it's running.

couple pumps and fires right up…

Do you think a primer bulb would cause harm to a diagram in the pump ?… I was planning on maybe 2-3 squeezes at the most to prime .

In fact, I believe that they have TWO.  One at the inlet of the bulb, one at the outlet.

Cut one of yours apart and let me know…🤣

No sir. One or the other was my point.

Been using it for several years now. No issues. Usually takes couple pumps and it’s charged…

Could you not have just run the ground wire to ground ?… I would not want to drill a hole in my dash… wouldn’t the “R” position on the switch power the pump ?

You can actually feel when to stop.  The bulb gets a bit stiffer when the float comes up and closes the needle valve.

Well... I know yer jokin', but if you think about it, how else could it work? 

 

Check valve at inlet and outlet... 

 

when you squeeze bulb, inlet check closes and outlet is open.  When you let go of bulb, outlet closes and inlet opens. 

 

Pretty much the same way yer heart works.

 

Also, it's the same way the mechanical fuel pumps work.  Just replace the bulb with the diaphragm.  They also have two check valves in them... which makes me wonder why one would need another check valve?  How is fuel draining back?

That make sense to me… and also I’ve heard talk on here about fuel running down the pulse line into the crankcase… but for that to happen wouldn’t the diaphram in the pulse pump have to be bad ?

I know… we’re cool. 😎
 

Edit:

You were clarifying… and I was saying “ primer bulb, and check valve both ?” because at the time of the posts, Jeff-C175 had not informed me that he was pretty sure that the primer bulbs had built-in check valves.

Not sure about the vacuum operated pumps, but on the straight mechanical pumps, yes, a bad diaphragm can dump fuel into the crankcase.

Yes. I can turn the pump off and run the carb dry.  I don't have a Wheel Horse still like it came from the factory all mine have been modified.

A vacuum pump is just as bad about dumping fuel in to the crank case.

Yep… I see the point now in the toggle switch… to be able to run the carb dry.

Did not pick up on that angle…

My bad… I should have said pulse pump instead of mechanical.

But anyways I see what you say… a bad diaphragm in a pulse or mechanical pump would allow fuel to flow into crankcase…

A lot of times I use the wrong terms, but usually you all can figure out what us newbies mean.😂

 

Thanks ,  @Lee1977

Knew what you meant when you said "pulse line" though, but I'm not sure that's the route the gasoline would take to get to the crankcase.  If the pulse line filled with gasoline, wouldn't the pump stop pumping and engine shut down?

[Horse Newbie 7,074]

Maybe, I guess…

never had a pulse pump fail to where gas flows down the pulse line.

 

But I sorta think if the engine was running, maybe until the failure gets worse, the pulse line pumping would not allow the gas to go “down” the pulse line…

when the failure( hole in diaphragm) becomes  too large, the pump would quit pumping and the engine quit.

 

Or am I looking at things wrong ?

Dunno!  It's been a very long time since I've looked at a pulse pump and why I'm conjecturing.  Maybe Lee can explain better?

I got a package today from @wheelhorseman / Wheel Horse Parts and More… the rock shaft kit, spindle/ axle ends top dust covers, and throttle lever handle for the 1984 Work Horse GT-1600…

Gonna be some progress on the Work Horse this weekend !

Edited February 18, 2022 by Horse Newbie

[Horse Newbie 7,074]

Can someone give me a tip on putting the throttle handle on the throttle lever ?

 

If I push it on, will it “snap” into place ?

 

The reason I ask is because I had to cut the old one off.

I am looking for opinions… would you paint the rock shaft Rustoleum Satin Black like the frame, transmission, etc, on the Work Horse, or would you leave it that beautiful WH red ?

[SylvanLakeWH 25,598]

I’d maybe heat up the knob with a hair dryer…

 

I’d leave it red…
