I still don't know why people call it a dizzy....
It seems to bother you.
I just called it that because sammy did. I usally call it a distriburator (sp?)
ever see one of those clear dist caps? makes me dizzy looking at it while runningR) sammy i havent had a chance to look at that flywheel will try to this evening
here you go sammy, better late than never its not a very good picture, but i cant expect much out of a $30 camera you may can do what i did, my spare a1 motor had a timing tab on the front of the engine, i used it and the pully to time mine
This keeps getting WEIRDER!
My distributor is in, and, the wires go 1 2 4 3 instead of the 1-3-4-2 it should be, runs fine, but if I reverse the wires, it doesn't go. I see the timing marks on the flywheel when on the NUMBER 2 plug wire, not the number 1 or 3 (if the flywheel was backwards)
Compression is 101,99,99,100 with carb closed, but when running, I just tested the number 4 it's at 50-75 PSI.
I'm getting frustrated at this, it won't stop leaking, it's not timing right, back fires, body looks like crap, tired of waiting for people, I'm losing steam on this... and fast.
I have never heard of someone doing a compression test while running. must have not run well with onl 3 cyl firing. You non running compression looks fine for a no broken in engine I wouldnt worry about that. Without seeing your jeep in person I dont know what other help I can give with timming. If you buy me a plane ticket I would gladly come help, always wanted to see NM
If I had a job I'd gladly fly you out R)
It ran fine on 3 actually. I was more curious than anything.
You don't run a compression test on a running engine, you do it with the the coil wire removed and the engine cranking.
As for #4, I would look long and hard at the valve lash.
Take the cap off, and look at which way your rotor spins. 1243 is just 1342 going backwards. You are probably just looking at it wrong.
Curiosity strikes (BONG!)
Do you have an early or late L-Head? They changed from direct drive gears to chain drive gears somewhere in the middle of the run. The rotor will spin in the opposite direction in the chain drive compared to the direct drive gears.monkeys
Chain drive MB L head
Guess that's why it won't run when I put it 1-3-4-2 R)
Sammy, The rotor will spin the same way (counter-clockwise) in either motor. However, like I mentioned earlier, you probably are thinking it goes the wrong way.
FWIW, In the chain drive motors the camshaft is the only thing that will spin the opposite direction. The direction is corrected by the spiral gears meshing with the oil pump. The oil pump of course is what drives the distributor.
Obviously, you cannot have the oil pump spinning the wrong direction or it would want to try and put oil back into the pan!
The rotors turn opposite directions - the cranks turn the same direction. The cams turn opposite directions. Oil-pumps turn in opposite directions.
Don't have to believe me, though. Ask Sparky. And look it up in Moses Ludels tune-up and rebuilding manual for the 1941 -1971 CJ's. Pages 139, 140 and 141 state it clearly.
Chain-drive L-Head distributors turn clockwise, direct-gear drive L and F-Head distributors turn Counter-clockwise. Page 464.
Firing order is the same for all Willys 4 cylinders. 1-3-4-2.
Or you could always park next to a CJ5 with the F-head and hand turn the cranks in the directions of operation, and watch what the rotors do.
And I was wrong on when they changed from one drive system to the other. Chain-drive came first, Direct-gear drive later.
But, like they say on the Nascar programs; "We looked it up, so you don't have to!"
Have a nice day.:hurrican:
I do not know who this "MOSES" guy is, but he is flat wrong. Haven't you ever heard the old saying "Don't believe everything you read"
Just grab a camshaft from each motor, and you will see which way the spiral gear is. I have had both kinds of these engines apart. The funniest part about what "moses" says is the oil pump turning backwards!
You might as well take that rebuilding manual and throw it away.
did you take the oil pumps apart?
They have different innards.monkeys
Nope, the machine shop did...
Wonder if thats why I'm getting super high 60 PSI oil?
Fresh pump? maybe.
I get 50 psi from mine driving at 1500 to 2900 rpm and 20 psi at idle once it's warmed up.
Cold it's 60 running and 40 psi at idle. 10W30 last oil change.:hurrican:
