Odd problem on an Allis C

[old]

Well went to fire up one of the Cs I have and it didn't run well. Its firing on #3 and 4 and some times on #1 but #2 no fire at all. Check compression on #1 and #2. #1 has just under 150psi so I figure its a bad plug but #2 has zero and instead of having compression it sucks when you put your finger in the plug hole. So till I open it up I'm guessing it has a suck valve and thats why its sucking instead of blowing. What say you guys??
Thanks

Get a spray bottle and spray tranny fluid into carb while it's running this has loosened up sticky valves for me ,and dump a couple of bottles of marvel mystery oil in the gas this will lube the valves up as well .

One was stuck real good the other one had a broken valve spring which had then spun around and up over the keeper. Funny thing is that was also the one with good compression

Stuck exhaust vale on #2 and a broken valve spring on #1

I have it fixed now. Sprayed PB on the stuck one and then used vise grips to turn it and a hammer to tap in down a few times and it freed up. Then took a spring off another haed I had and put it on to replace the broken spring and its up and running good now

I wish i did, but if i had that thing, i would have the block too, and would be working on putting it all together

I thought somebody redone a head for your other tractor

Yes, DickL

i'd have thought intake stuck closed since you had suction but no compression....
these things will fool ya!

Yes they do. What I thought was real funny is how #1 had good compression but it also had a broken valve spring on the exhaust valve. And the way it was broken was also very odd. Some how it have worked its way up and over the keeper cap. I ended up having to spin the spring up and off the valve keeper cap to get the keepers out so I could replace the spring
