What is this ?

[Lagersolut 743]

Had some time this morning before the birds were done and company arrives getting this no name ready to try to get  started.

 

 

I've never ran across one of these levers on a fuel pump - it's on a K341 my first though was a primer but it has a hole for a cable .

It is a primer.

Never seen anything like that! Maybe it's a primer or a way to disengage the fuel pump? Could pull the plunger away from the cam it runs on.

I've seen pics of those levers.

I agree that it's a primer 

The hole for a cable may be for usage on another brand or types of machine.

If I get good flow/prime with the manual lever can you assume a good flow with the cam lever inside the crank case ? 

 

I’m going to start off just trying to get this running with a short piece of fuel line into a small portable can to see what I have ... fuel lines on it are shot .. also water in the tank .

Agreed it's a priming lever and it will only prime if the camshaft lobe is not in a position to be lifting the pump diaphragm. Otherwise you have to turn the engine over a few degrees in order for the primer to work.

Never assume, you can test the fuel pump with a vacuum gauge on the inlet side, if the vacuum is non existent or drops off the gauge within a few seconds the valves inside the pump are leaking.

 

Or you can test on the outlet side for pressure and leak down.

I have a fuel pump in my collection that has one of these on it and by the looks of your block It looks the same as the one that I have. I believe it came off a pardon me for saying JD. Was a 10 horse

Got it running - no smoke runs like a top .. cleaned  carb - new points   plug , new oil ...

My 1055 has a wire attached to the primer that comes through the grill, not too fancy lookin but works well and easy to get to.

Just for reference, in my case. I own a pair of Arctic Cat snowmobiles with K301's and they have that lever. The cable runs up to the dash panel for seated starting of the engine. Seems I only see this type of pump on an engine that has a remote fuel source, often far away. Makes priming much easier. They are a bit hard to find. I never throw them out. I put them on any WH I get when I have a spare on hand. Much easier on the starters to just pull the lever a few times if it's been sitting a while. Instant cold starts every time.
