Help a kid out...... please

[muddcakedmaniac]

Hey im 16 and just recently got my license, I have a 1987 jeep yj wrangler that i have spent the past winter rebuilding with my dad. We redid the whole interior with durabak, painted the whole underbody and frame with por-15, put in a 4 inch bds lift, new 33s replaced the vavle cover and much more.

But now after driving, the carb is just a pain, from starting to geting it to idle, and even when i think the idle is good, when i go to stop it wants to die unless i give it gas, so im looking for a new one to fit right on without much work. Its a 258 4.2 inline 6. I was thinking maybe a weber but i wanna no what you all think so if you could give me some info on what would be best for me that would be great.

Thanks

a weber can be expensive , but well worth it . maybe try a motorcraft carb from a bone yard if money is tight ?

search for the motorcraft (ford) swap from an I-6 300 cid i believe = pretty straightforward deal (would do it myself if it weren't for the smog testing here in vegas...) - there are more than a few writeups on this board alone... should be able to pull it off for LOTS less $$$ than a weber and w/better results! g'luck!

If it dies out when you are coming to a stop, it could just be clogged venturis. Its very common on the Carter carb and cleaning that out can make a world of difference. Try it before you go buying a new carb... Its easy and free. (Check out the how to section or search online.)

Carbs kick a$$! No wait they kick your a$$!

There's a few different routes you can go here.
1) Modify your Carter carb. The vent tubes in the venturi cluster are too small. It was a bad design. There's a link on how to drill them out and to what size. I'll look for a link, or maybe someone will beat me to posting it. It will solve the cloggin problem mentioned above. Just cleaning it alone will only be a temporory fix.

2) replace with an aftermarket carb. I have heard many mixed opinions/reviews on the Weber. Some folks just plain hate 'em, and others praise them. If I were to buy an aftermarket one, I'd go with one of those fance Edelbrocks that claim to work great at extreme angles. I think 4WD Hardware and Quadratec both sell them.

3) Do a Motorcraft 2100/2150 swap. This seems to always work well for those who do it. There's an adapter plate and gasket needed (Mr Gasket?) and you'll have to modify/fabricate your existing throttle linkage. These carbs seem to be right at home on the 268 I6's.

Keep us posted.

Your making a mistake.

 

[TwistedCU]

Your making a mistake.

[muddcakedmaniac]
