Ready to crank the Yellow Peril -- STICKING VALVES! 140-160 1973

Last spring the Yellow Peril started OK. After replacing the transmission and shifter boot,
since I had to undo the bottom of the heater to get the carpet out to change the boot,
I went ahead and attacked the heater, which had been NF for years.
Finally got it ALL together a few days back and went to start it, put a gauge on the fuel sys
and found the fuel pump was seized. I put another pump on it which ran OK but would not
put up any pressure. By that time I was also able to free up the seized one and got O-rings
to reassemble it. I installed it today and fuel pressure came up slowly. |
Then I found that when I opened the throttle I didn't get the injector clicks.
(I did last week!) Any suggestions on this fault would be gratefully considered.

I went ahead and shot a little starting fluid into the manifold and cranked it.
Sounded like it was turning VERY freely and after a muffled BANG I noticed the aircleaner
cover was off as was the hose from the manifold to the aircleaner.
After fixing that I pulled the valve cover and found 4 pushrods out of place.
I put them back in place and had the DW crank it again while I watched.
The valves open OK but close SLOOoooowly. While waiting for the valves to close,
the pushrods come loose from the rocker arms (4 of them).
I talked to a local mechanic and he said that if I could get it running they would
probably free up OK by themselves, with which I agree.
But I can't run it if the pushrods keep falling out of place!
I would rather avoid tearing the head down and cleaning it right if possible.
The engine only has about 15,000 miles on it, scattered over 6 or 7 years.
Trying several different tools I finally settled on some short pieces of streetcleanter
bristle, about 1/8" x 0.020", spring steel, one slightly bent on one end.
I retch through the valve spring and lifted the seals up off the valve guides
of the affected 4 cylinders and plan to squirt some ATF in on the valve stems.
Anybody got a better idea?
