Ok, I have a rochester 2se carb in an 85 chevy s-10 (2.8L v6).
I am getting GAS fouling now.
It was way overdue for a rebuild (gum and varnish from a few years sitting around before rescue). Got the correct rebuild kit.
It has been running great after I did the valve seals, new tranny pan gasket, and thermostat.
Now I went to tackle the carb rebuild.
All went pretty smoothly. Took it apart and soaked all metal parts in Berrymans chem dip overnight.
Toothbrushed it the next day, and compressed air blew out every orifice. Changed all gaskets, changed the float seat and needle, spring with the little metal BB and cap (forgot it's name). Linkage is back on same as it was before.
Got a new EFE insulator for $90.00 (what the carb sits on).
I took pics of the carb before removal and made a sketch of vac lines. So I'm pretty dang sure I have that connected as it was before.
Problem is, i can't get it to fire up now without it fuel fouling plugs.
The float is ok., no holes and is floating, adjusted as per spec in the rebuild kit (plus it's the same float just the rebuild kits new needle and seat. havn't tried bending the float up or down as I'm not sure which way to do that first.
As for the main jet needle\pin in the center of the carb (which goes up and down in the main jet).
Starting-wise, I got a little different results when I adjusted it. **It's adjustable by turning the other needle which is threaded and moves the main jet needle up and down. So when you turn that either way , the needle in the main jet sits higher or lower depending on which way you turn it.
What height should the needle sit in the main jet? I got it to start and run (although VERY poorly) before when I had it sitting lower in the man jet - but this is far from where it was before...and it ran horribly and had to be given gas to run (woudn't idle).
With it adjusted to where it was BEFORE the rebuild, it won't start...ever. Tries here and there, but no go.
With it sitting lower, while flooring the pedal...I got the chug-chug......chug-chug-chug...and it ramped up all the way to running if I gave it constant gas over some time (although poorly because by that time some sparks were obviously fouled out). Take the the gas pedal off and it chugged back and then died.
I did NOT try adjusting the idle screw yet.
I'm really enjoying repairing these things myself - but this ones beating me up BIG TIME. I took it slowly and carefully and I still can't beat this.
Tried starting fluid in the top of carb with no result.
Any help please? So close yet so far.
thanks,
Joe
