Since this is a 258 with a weber, there is no choke stove. Its purely an electric choke.jsinajeep wrote:X2 on the choke. Check the choke stove line to and from the manifold and also the electrical wire to the choke cover.

Another thing I just thought of...Occasionally from time to time while downshifting it will backfire once real quick thru the carb even if the Jeep is warm so I don't think it's entirely a choke issue?
Vacuum advance is working properly as is the mechanical advance. While I was in there I spotted a weird issue that I think is the problem. With the rotor off of the distributor I held the mechanical advance closed and rotated the guts of the distributor, IIRC there's supposed to be little or no movement but there was atleast 20*-45* of play when I did this plus there was a 'crack' that came from the distributor that didn't sound quite right. I put the rotor on and rotated as far to the right as it would let me then put everything back together, the Jeep fired right up and idled just as good as it used to then after I gave it some gas it proceeded to run like crap. It took nearly half the skinny pedal to hold it at 500rpm's then I was able to get it up to 2Krpm's but for seemingly no reason it backfired thru the carb several times and tried to die but held a really low 300ish rpm idle.Stuka wrote:Grand_Wag_85 wrote:I'll check the choke.

Make sure your vacuum advance is working properly. Wouldnt hurt to check the mechanical advance as well. But if the vacuum advance didnt work right, the timing would not change as it should as throttle is applied and let off.
After pulling the shaft what exactly am I looking for? Is there another pin at the top of the distributor or a key way that holds everything in alignment or is it just pressed into place? It's been forever since I've torn down a distributor.Stuka wrote:Pull the pin on the gear and slide the shaft out.
I did the timing chain on my J10 in about 4 hours. I still have photos of the complete job, step by step. Its a lot less work than on an AMC 360. You dont have to pull the distributer, you dont have to pull the water pump, non of that. I did pull the radiator. But otherwise the cover it by itself.
