FYI, the return line isn't all the way at the top, but it's between 10
and 11 o'lock. Checked it today between botched start-up attempts. I
made the mistake of jumping right in and turning it over. That works
before 10 am, not after lunch for sure. So I get out lift the cleaner
assembly enough to put my rubber hose to work and yowzers if the
stupid choke isn't completely closed. It's 83 deg outside! So I put
the hose in, jam the pedal down and crank and crank and crank -- not
even a cough. So I leave the hose in place with air cleaner off and
go check some on some things in the lab and come back 45 minutes
later. Again, pedal down (I figured I haven't tried much of this
lately and maybe I should revisit it). The first crank it pops once
and then dies. Crank, crank, crank. Thinking maybe I've run it dry,
I pump once and crank, crank. Twice more, crank, crank, crank. Start
smelling gas, so I go back inside to post this message. I'm really
freaking out now. It's got to be something simple that I'm missing
here. Maybe not. Oh well.

FYI, the return line isn't all the way at the top, but it's between 10
and 11 o'lock. Checked it today between botched start-up attempts. I
made the mistake of jumping right in and turning it over. That works

Re: '88 YJ 258 ci with carter Hard Warm Start
 
Jut try tossing a 1/8 cup or a couple tablespoons of gas down the carb
and see what happens.

If it fires up, you have a hole in the gas line on the suction side of
the pump or a dead pump that is letting the gas backflow to the tank or
a torn diaphragm on the pump.

Does the oil on the dipstick smell like gas?

Oh, the choke is an electric timer job.

It will be totally closed after 5 minutes and opens according to how
long 12 volts has been going to it. Piece of crap actually because it
doesn't have a clue how hot or cold the engine really is, just how long
it has had 12 volts.

Re: '88 YJ 258 ci with carter Hard Warm Start
 
Jut try tossing a 1/8 cup or a couple tablespoons of gas down the carb
and see what happens.

If it fires up, you have a hole in the gas line on the suction side of
the pump or a dead pump that is letting the gas backflow to the tank or
a torn diaphragm on the pump.

Does the oil on the dipstick smell like gas?

Oh, the choke is an electric timer job.

It will be totally closed after 5 minutes and opens according to how
long 12 volts has been going to it. Piece of crap actually because it
doesn't have a clue how hot or cold the engine really is, just how long
it has had 12 volts.

Yeah, I hate those. I have one on my Grand Waggy and I wish I could find a
good alternative (with the exception of a manual one).
