Just got my stock 6/74 Fj40 back together. Not a rebuild, but a cleanup from the firewall forward. New headers, fuel pump, pcv valve, rebuilt alt & starter etc. etc..... From my inspections I have no vacuum leaks. Everything is sealed up and looking good.
The truck runs and starts well but with cold starts it has a little trouble idling even with the choke out (to first "click"). The choke does not make the idle increase excessively, it just smoothes out the lower idle (650 rpm) to where it keeps running. On the road, if you hit the gas, it hesitate (no pinging) until it hits a little higher RPM and then it runs great.
Figured this is a fuel delivery issue (rich - lean??). Sight glass has gas and the acc pump seems to be working.
I looked at the factory service manual and the archives for carb adjustments. No real help. Anybody have any ideas on ho to adjust the carb to fix these issues.
Regards,
Scott
