hey everyone i'm new here but i have an old toy with 245k on it and it runs great (well was), just did the head and timming chain and it ran awsome for three weeks then it started flooding when it idles any ideas what it could be

 

ok my truck was flooding cause it wasn't burning the fuel i think cause all my plugs are wet with gas and barely firing anyone have any ideas what it could be i need my truck back plz reply

 

Check the timming

 

yeah check the timing but also check the plugs, my dad has an 84 truck 22r and had some trouble with excess gas not being burned, he changed the cap and rotor got new plugs (alittle better quality) and it works fine (the carb was at stock adjustments). Im sorry, this might be a stupid question, but does it have a carb or is it F.I.

 

im guessing a carb. (judgeing by the forum and assumtion its stock (no engine swap))

 

Blown accelerator pump diaphram

 

Yah, I have a similiar issue, haven't solved it yet, but I have a lead. I had the EGR system off to check it and I had to pull a few vacuum hoses so I could get at something...and what did I find? Gas in a vacuum line! I'm 99% sure it shouldn't be there. The hose I pulled goes to the CB (choke breaker, another one of the diapragm activated devices on the carb), it's the one at the back right that has the "jet" inline (looks like an inline filter in the vacuum hose).

I'll post back if it is the solution to my rough idle/stalling/gas pouring out the exhaust issue. I haven't been able to run since the EGR system is off and I'm waiting for a gasket that they had to order.

 

So just after I last posted I started studying the vacuum diagram...I bet it is the AAP (aux accel pump) diaphragm. Not sure if leiniesred meant AAP or AP? The CB shouldn't have gas on the other side...however the CB and AAP are essentially conected through BVSV for the AAP (cold engine only). Gonna check it today.

Might be something for you to check too. Sounds like we have similar issues.

 

Yup that was it...

AP or AAP, either way, you're dumping extra gas into the intake...

AAP is cold engine only though...

 

Awesome! I like working on carbs. Hopefully when I get get a new 4X it'll be an '84 - '85.
