Title: Boiling fuel
Post by: blink77 on July 05, 2012, 01:27:17 PM
I have a dilema with my 79 2.3. It runs perfect. When I drive it
for 15 mins and shut it off, it will start like a champ if you start
it up in the next 5 min.. But if I let set for over 30 mins., when I
go to start it, it will fire for a second and then just crank. This is
repeatable every time. My wife wo'nt drive it, and I'm not too
happy about it either. I have a strong bat. in it, and if I hold the
gas petal to the floor for 1-2 mins while cranking I can get it to
start. I change the Dura-spark box---same results. My initial thought
was-stuck neddle and seat. Next I took off the air cleaner after
trying to start and looked in the carb.. It looked like someone was
frying bacon. And this was after it had sat for and hour. I am at
my witts end.The car has been de-smogged. No cat no egr no smog
pump, and it runs perfect. It did this before I de-smogged the car
also. I don't understand where that kind of heat can come from.
Someone must have had a similar problem. I am open to any ideas.
HELP!!!!!!!!!!

My '80's all had a large bakelite? spacer between the carburetor and the intake, does yours have that still?

Just a quick question...whe n the car fails to start after it has set for a while and you finally get it to restart, do you get a big puff of black smoke out the tail pipe like it's flooded real bad? It sounds to me like the fuel is draining into the carb from your description of it looking like bacon frying.

When it finally starts, it will idle as if to say "WHATS WRONG WITH YOU"
I don't have to rev it to clear it out or anything. But since we last chatted, I put a carb from a 1980 on it. It's not exactlly the same, and
I had to change some things. It runs OK, but the other carb has a
performance advantage. BUTTTTTT it doesn't boil the gas. I really
think my original diagnosis is correct. Bad needle and seat that lets
the gas in the line that is under pressure flood the carb. Where it gets
the heat to boil the gas an hour after being shut off, still baffles me.All I know at this point is it IS in the carb. BUTTT- I'm still willing to listen to
any and all ideas concerning this problem. I think I'm going to put a new
needle and seat and check the float and float level in the original carb
and try that again, as it ran better with that carb for sure. Thanks again
for the reply and I'll let you know how the thing finally ends up.

I do have that spacer under the carb. I think I.m
making headway on this.

There may be some main jet differences causing the carb u just installed to be a little less than spectacular. I would get a kit and freshen up the original carb and give it a try again. It might cure the issue. Good luck!!

I bought a 25.00 carb kit. All I
used was the needle and seat
and the top gasket. Solved the
problem. Thanks for all the input.
