Motor timing 180* out?

[Hedgehog]

I'm just wondering, please no disrespect. Have you taken this problem to other boards, if you have how did they react to your seemingly never ending issues, but not seeming willing to address those problems directly?

I admit to have had several long drawn out issues, but mine have a easily followed trail of occasionally folly, definitely listening to those that have already treaded the path I was on and in the end I have found a satisfactory conclusions due in no small part to the advice freely given on this one board.

With that I say good luck to you sir, but consider this, if you can't fix the CJ, there are many perfectly good Toyotas and Nissans waiting for a good loud muffler can and a body kit. A still decent CJ can always use a good home.

Yes indeed Hedgehog, I am a member of 5 or 6 boards, amongst them Jeepz, JeepForum, Military jeepers among others. My neverending issues are primarily on account that I have very little free time to work on this Jeep which until September, was running just fine as my DD

I hope everyone had a Merry Christmas, kinda misanthrope for my housefrau and I (economy troubles) I did get Christmas Day off as one of my two days off per year. I realigned the distributor and did my best to reestablish TDC using the no. 1 spark plug hole and a remote starter.





Thereafter I tried starting 'er up but I could only keep 'er ruiing by keeping the revs up to 2000 rpm, otherwise she'd stall out. I'm really coming to my wits end with this damm thing.

Why didn't you leave it alone?
It ran fine didn't it?
When you reinstalled the dizzy, the drive gear inside the engine moved the rotor so it doesn't line up with the rotors post when it should.

Hi LG, hope you had a good Christmas. I was leaving it alone, save for preventative maintenance. What got this debacle going initially was a sunken float in the carburator and leaking throttle shafts. When this was not the last fix I received several messages about ignition timing, distributor position, investing in a DUI system (which I would if I weren't so broke) that led me down this long and winding road, so to speak.
The distributor was positioned in such a way that the vacuum advance module was pinching against the upper radiator hose. Using the old finger over the no. 1 spark plug hole I re-established TDC (as shown by my pics) but it is not out of the realm of possibility that I may have installed it 180* out, but I'm leaning toward a large vacuum leak, if i can find it.

The picture you show'd had minor contact of the vacuum hose on a secondary coolant line.
Correct?

Oh no Lumpy, I made the same mistake in thinking he posted a picture of HIS engine in that thread. ..... His is the EXTREMELY messy engine bay with wires everywhere and his Vacuum advance is turned near his bypass hose. The following picture is of my engine compartment. The position of my vacuum hose looks the same. Well not all messy and full of wires like his is, but the dist. position is the same. I came up with a finger device to pull the hose away from the Vacuum line.

Posi - Thanks for the links. I had a feeling that he was bleeding on other boards the same as ours.

IF these are the pics of TG's engine bay. There's not a thing to worry about with the minor hose contact.
Plus-it was run'n.........

I honestly have stopped believing that running is the point.

 

[Turbogus]

It runs but only with my foot on the throttle keeping it at 2000 revs

It runs but only with my foot on the throttle keeping it at 2000 revs

That's only because the advance curve is let'n it kinda run.........

What fun would it be if something/anything ran as well after wrenching as it did before. There is no end of good advice to ignore now.

 

[Turbogus]

No end of good advice to ignore I like that!

So, Saturday I buttoned up the distributor and left all vacuum devices disconnected feeding from the carburator, plugging all of the ports as I went. Using the remote starter so I could see what's going on in the engine compartment, after two tries she started up! However I noticed fuel puddling on top of the Air horn on this AFB. I shut her down and mopped up the fuel drying the top so next try I could see where the fuel is coming from. Second go the fuel leak was from the accelerator pump shaft as it passes through the Air Horn at the point in this photo;


I seperated the Air horn (once again) from the Throttle Body and all still looked pristene, clean and free of any debris. I took note however that the Accelerator pump shaft's Neoprene rubber grommet does not seem to fit the "Acelerator Pump Well" enough to keep backfeeding or fuel out of the top. This is a new Acelerator Pump that came with the Echlin rebuild kit. In my searches the two sizes listed are 13/16 inch for the neoproene and 11/16 inch for the leather. The original pump that came with this 1988 mfd. AFB seems to be made of rubber and doesn't seal at all given it's shrunken size over the years.
As the AFB's go this one isn't ancient, using the old leather pumps (which are smaller anyway) are there different sizes of the neoprene cups available?

There's an Acellerator Dishcharge Check Ball resides in the bottom of the Acellerator Pump Well, isn't there?

 

[Turbogus]

I got some vinyl tubing and a funnel and tested the Needle/Seats with the Air Horn inverted (gravity working on the floats) and ran fuel down the line.
The Primary Needle began leaking right away. From the many rebuilds of other AFB's I had a small collection of Needles and Seats



so I swapped out the needle and it held fuel. I don't know if I'm out of the woods yet, but this is just one more thing that was wrong with this 9638.

FINALIZED
Black Betty is on the trail again, idle down to 600, timing set and running smooth....at long last and 136 posts/counter posts, Thanks to all whom have posted their insights and opinions. But for one final pitfall, dropped the throttle return spring and it's lodged somewhere between the body tub and Transmission . A quick trip to my best friends' place and it's now FINALLY on track. Now on to the mods before this issue began.

 

[Torxhead]

Thanks for the update Gus, it took quite a bit of work to solve that one, great going!

 

[Turbogus]

You got that right Torxhead, if I see anyone else posting about these AFB's or AVS's flooding I'm going to cut and paste what I've learned
