Re: Rochester E2SE and 2SE carb jet question
Last time I messed with one of these carbs, it sucked.
I installed a set of headers on an old jeep with a 2.5, and it wouldn't run properly after the install. The damn thing was so lean, it barely had any power.
I had to drill the jets out to huge holes.
The secondary barrel has a trap door that opens and it controls the secondary fuel jet - opening the needle in the jet orfice more as the door drops open. I had to hog the BAG out of that jet. I did finally get it right after removing and replacing the carb several times.
For the amount of skrewing around I had to do, I should of just bought the Weber conversion.
As usual, I always recommend the Weber conversion. I don't know of anyone who has not been very happy with it.
Sorry, I know it's not what you want to hear, but you will see that rebuilding your carb is going to be a PIA.
