Default It's a thumper...

Today I hooked a gas line to the carb, and fired the old beast up.
John R. Hollingsworth co, ser #467

With a crankcase full of 10W40, it did not even smoke! Not bad for a 1964 engine!

Oh, as a bonus it makes power. The CPS meter is interesting...

Now I will setup a proper gas tank for the thing, and get the airfilter back on it.

The project continues, air filter sorted out.

The dreaded fuel system. Original fuel pump, shot. No wonder they bypassed it. I removed it and covered the hole. The engine runs well when gravity feed fuel. I have a pulse operated fuel pump that I thought I could get to work. Not quite... Not exactly sure what I am going to do for a fuel system now.

My question for the masters of military antiquity, did this genny have a gas tank when new? Or did they simply hook it up to a jerry can?

I may end up designing some sort of clamp on gravity feed tank...

As I do not know what engine your unit has and what electrical system, You could use a 12 volt Electric fuel pump if you have a 12 volt electrical system. The vacuum pulse fuel pump only work well on single and twin cylinder engines. If the fuel pump you have is one of the small, about 2 inch, square ones, you can still buy them and swap parts around if the arm design of your is not available.

Sorry for the confusion, it is a single cylinder Wisconsin. Magneto ign.

It should be possible to locate an origional fuel pump, perhaps I have not tried hard enough yet.

It is possible that the pulse pump I have isn't working correctly. I have not taken it apart to see.

Building a small tank to clamp to the top seems like the simplest solution.

I discovered a electrial gremlin yesterday as well. I had a fair load plugged into it, and I was losing power down to about 1/2 or less and then it would fluctuate. Something is odd, I will find it.

Pat,

You say the engine is a Wisconsin. Is it a true Wisconsin OR a Military Standard Engine built by Wisconsin?

Default A completed project

I will remember to grab a camera and get pix tomorrow.

Paint job is done, 220V outlet installed, and it was ready to assume the position of honor out there feeding my workshop. I can move it with the hand truck, barely.

This thing is incredible! I turned on all the lights, and exhaust fan. Then I turned on the air compressor. That put the load up a bit. turned off the exhaust fan, and played with a welder... It struggled, but did not give up easy.
Way, way past 3000 watts.

Default oops

It tried to self destruct last night.
I started it up and was fiddling around in the shop while it warmed up.
Vroom! What the ....

When I got out there it was running about 7000 rpm! The linkage had fallen off the governor! I replaced the missing/broken cotter pin with a new one. All is as it should be. It survived! I am amazed.
