Hey guys new to the forum here and I really like what I'm seeing. I recently bought my first Jeep and I bought a wagoneer, mainly because I love the lines and the fact that I grew up riding in my dad's wagoneer and that whole feeling has never left me. The issue I'm having with mine is that it was upgraded after the engine was rebuilt with the edelbrock performed intake, and carb. I'm not so sure about the heads. I replaced the mechanical fuel pump and it still starts like crap. I set the timing adjusted the carb and it doesn't seem to get fuel at all when starting. If i turn it off and fire it up immediately it starts right up. What can I do to fix this?
if you just barely crack the fuel line where it goes in to the carb, and have someone turn the key while you look, the gas should spray everywhere. If it just dribbles a little, your fuel pump is not working. It should spray like crazy.
I've found in the older cars, that the lobe on the camshaft that pumps the mechanical fuel pump wears down and doesn't pump enough fuel for the engine. Now I run elec fuel pumps on all my stuff. That may be the answer for you.
Beauty is in the eye of the jeepowner.
Ok, I have done all of the above and I believe I've figured out what the problem is but I do not the proper resolution. Gas seems to be boiling inside of the Carb. I'm not sure how to remedy this I was told use a spacer but I'm not sure if something else could be the issue.
I got a insulating space with my carb rebuild kit. When I removed my emission stuff I left the vent tube open and the fuel would evaporate away in a couple of days. I just plugged it with some RTV and that stopped that. It could also be emptying through the power enrichment valve.
My final solution was to replace my mechanical pump with an electric.
If the prob is still present after clocking the filter correctly & you have good fuel press, then do the phenolic spacer. I was having probs with fuel boiling in the bowl leading to lots of cranking before finally firing off as well. Remember not to tighten down the carb too much though, or you will crack the spacer. Tighten it a little at a time in a star pattern like you would anything else.
Update: Ok I've installed a 1/2" phenolic spacer and routed the fuel filter so that the return line is higher than line going into the carb. The starting has gotten significantly better however it's not perfect. After about an hour the gas seems to evaporate and I have to crank for a bit to get it to go. Summer is approaching and being in Florida I only see it getting worse I still think I have a heat transfer issue any other ideas?
