Throttle/mixture problem

[sweetpeet]

I'm not sure what the problem, can't quite put my finger on it. I didnt have this problem a week ago. But heres what's going on, I spent about 2hours trying to getting fuel to the carb, at the end of which I found that I needed to give it a little gas to fire up. It has an electric fuel pump and I didn't have to give it any gas before. Then while reving it to warm it up a little bit, some smoke came up from where the shifter is. Now, I can't put the gas pedal to the floor anymore. Almost as if the firing order is off but I'm positive that it's not(like I said it was running smoothly last week). Another thought is that the trany fears aren't engaging completely. I don't really know tho.

It keeps jumping when I lay down on the throttle

Can somebody give me some insight, please??

i think you might have timing chain .jump time. that happens .when you shut off engine it jumps. when was the last time it was changed

is your cat clogged?

 

[sweetpeet]

Catalytic converter? It's a 75 jeep cj5 it doesn't have a cat nor do I have any pets lol jk

maybe a bad alternator?? Possibly alternator, im not too sure?

 

[CJDan]

you may need a new alternator, you could have had a bad one for a long time, its just finally giving way now, so its not pumping gas to well because the alternator cant produce current, and gas is possibly going down underneath and clogging/burning up.

No, electrical is all fine. I think I may have figured out the problem over the weekend. I think my finicky eldebrock needs adjustment, I'll have to look up the factory settings.

I have the Holley on my 360 and everytime the temp changes greater than 20 deg. and humidity goes way up or way down it is time for a little tweak. Part of the problem with carbs.

 

[superj]

wow, i never had to adjust any of my carbs like that. the only carb i have trouble with is this weber 34. other wise, not a bit of trouble on weber 32/36, quadrajets, motorcrafts, honda carbs.

I am not a fan of Holley carbs, it is what came on the CJ when I got it. I am looking to see if I can scrape enough $$$$ for a injection system of some type for the 347 I am building right now. If need be I will go edelbrock, had good luck with them in my Bronco.

That's funny, I had a Holley when I had a 304 and I liked it slot better than the edelbrock that I have now on my 360. The edelbrock is too finicky and I go to adjust it to make it run smoother and it gets all out of wack. I prob should have gotten another Holley or a webber, I hear they are really great on inclines. But if you do go with edelbrock good luck with that.

i think you guys should get an adapter and run a rochester quadrajet. that was a damn good carb on my 79 stepside. my buddy said he had one on his k5 and it never had problems anywhere he went off roading

 

[82CJ7JEEP]

Wow, that is funny. Wonder if it could be the different environments? I still have an older 650 double pumper, maybe I will have that professionally rebuilt and try it. Probably cheaper than a new edelbrock.

Vacuum leak?

 

[superj]

Isn't a 650 dp going to be to much carb for a 360?

 

[82CJ7JEEP]

Super, The 650 will go on my stroked 302, if need be once final compression, HP numbers are established I will detune it to 600 or 550 cfm. I really want to go fuel injected but with some personal family issues that have come up I don't believe the money tree will support it.......

 

[superj]

yes sir, i understand. i feel the same way
