i'm thinking of just getting a holley 4175, not because i don't like quadrajets, but because i don't have time to dork around with a q-jet.
Anyways, what recently happened, after running ok is now i have no idle and i'm getting flooding.
The only thing i did was to adjust the secondary throttle plates to open more (the plates, NOT the air flap doors) and then did some "spirited testing" let's just say.... The jeg's reman q-jet shipped with the secondary plates really not opening at all. i got them to open about 30-40 degrees which is enough for now. i did this Monday night.
So, Tuesday morning, immediately after doing an acceleration test, i immediately noticed that the low speed and idle wasn't normal/as smooth as before. After work, i did another "test." After highway cruising about 15-20 mins came to a stoplight. Engine was really idling rough at this point. Then, at this stoplight, did another "test." After this is when the stalling/no idle/flooding happened at the next stoplight. This was Tuesday and before this everything ran fine.
-----timing very advanced but don't think this is the problem.
---- Choke works fine
---- fuel pressure last time i checked was about 5.5 lbs at idle. As soon as i open throttle it goes down to about 2.5-3.5.
---- "Normal" WAS 1000rpm neutral, 600rpm in gear. Won't do any of that anymore. If i put it in neutral and keep my foot on it i can get it to idle 800+rpm all day, as soon as i let up it putters out.
So to Sum: Engine will no longer idle and getting flooding. Ran good until immediately after adjusting the secondary throttle plates to open more and after doing acceleration tests.
