PM out.

I checked the clearance between the shut off lever and the retainer when cold and got a tight .010. Pulled it apart and removed .010. Now, when cold I have .020 clearance. It started right up, I let it run to get to operating temp and rechecked the clearance ... it closed up to about .016...

BINGO ... maybe. I KNOW the lever is free when its cold. I checked that a MILLION times. BUT ... I Let it warm up and pulled the cover. The lever is "less free" and almost binding when the engine is hot. I remember from the TM that there is a spec clearance between the shaft and that...

Is that a bottle of Black Label your friend is pouring? I haven't had a taste of Scotch in over 25 years ... but right now I am being SORELY tested!!!

Its now about 2 hours later. I let the truck cool down, armed myself with tools, brake clean and a step ladder and had my wife drive me back to try it. Of course, its raining. ... and ... it started right up just like it always did and settled down to a nice 850 rpm idle like none of this...

Well, I just got home from a 4 mile walk. The engine starts great. Holds an idle about 850 just where it always ran. Once it reaches temp, it begins to hunt at idle ...200 to about 900 rpm. Turn it off, let it cool ... its starts great and hunts as it warms up. Since it never died while...

Not yet. Work and other stuff happened. I did start it cold yesterday. Fired right up. I ran it for a while and everything seemed OK. I'm back on it tomorrow. (Tuesday)

The timing is correct. I ordered a new HH from CHINA last Friday. I was figuring I'd see it by the end of the month but it was waiting for me when I got home from work. 6 day shipping and no charge. anyoldways ... I'm getting pretty good at pulling the HH out. I ripped out the old and...

Actually ... we're just killing time until the parts (i.e., new HH) arrive. I will be checking the timing tomorrow in the AM when its a bit cooler, but that's about all I can do for now. soanyoldways, as for when humankind was capable or producing the precision machinery required to build...

You also should consider finding or building a machine to test the HH when its rebuilt. Such a machine will have to provide fuel at the proper rate and pressure, spin the shaft AND move it up and down and, finally, measure the output pressure and volume at 6 ports.I have spent some time at a...

We shall see what there is to be seen.

New News ... I just came back from the autoparts store with a couple cans of Brake Clean. The engine will start and run as long as I spray BC into the intake. When I stop spraying, the engine will continue running for a bit and then die. If I pull out the hand throttle while cranking it...

I would have thought the quill was OK if I could turn the engine by way of the jackshaft and use that method to align the red index on the gear. Further, I would have thought the quill was OK if I was getting fuel out of the injector lines when cranking. anyoldways ... it is something to check...

I really do appreciate the helpful suggestions and reminders of stuff I might have over looked or done wrong. I do have to apologize for the long posts ... I guess I'm just moving air so's I can clear up the fog of frustration. After reading more HH related threads last evening, I have come up...

I didn't sand anything with sand paper. I used 600 grit aluminum oxide lapping compound on a bit of soft felt and followed it with a bit of 1000 grit emery paper. As I explained that was just a very little stiff spot in the area that the plunger sleeve rides up and down. I was very careful...

Thankyou. Good photo for reference ... but mines OK.

Thanks FLAson ... I gave that a try yesterday. I even tried moving the control assembly back and forth slowly to see if it makes a difference. No change. But I did notice that the control assembly does NOT spring back to the 7:00 O'clock position when cranking. It actually is a little harder...

Before the job I read nearly every thing (manuals AND SS threads) I could find on replacing the o-rings . But I didn't come across this one in my search. Good thread ... lots of similarities. I forgot to mention that I have NO smoke when attempting to start. The flapper on the exhaust...

No. If I had, I would have put it on the truck the third time I took it all apart. Well, maybe the forth time ... I am kinda stubborn.

It occurs to me that I have had a similar problem about a year ago. I ran out of fuel once about a year ago ... and it took FOREVER to get the truck to start. But once it did ... all was well with the world.
