Subject:fuel system thoughts? Date:Mon May 4 09:33:55 2009
yesterday i took my 65 pacer on the backroads of indiana for a nice 30 mile
round trip. about 1 mile into the ride i was getting that bog down BLAAAA
sound in third gear. first i thought maybe it wasnt getting enough air even
with the choke open. so i took off the air filter and it seemed to help for
about 2 miles. then if i closed the choke almost half way it helped. so i
figured the fuel flow was too slow. then after it ran a few more miles the
choke vibrated back open and it seemed to run better. once i got about 15
miles at my turn around point, i was at a stop sign and she started to bog
down while sitting still. i look down and fuel is flowing out the back of the
carb. i shut her off and closed the petcock. i figured the float was somehow
obstructed. i took the bowl cover off removed the float pin and needle and
spring. didnt see anything and blew off everything the best i could anyway.
reassembled the bowl and put the air cleaner back on and fired her up. about
1/2 mile she bogged down again as i turned on another road, i pulled off the
road and she died. so i kicked her again and after that she ran fine for the 15
miles home. EXCEPT when i would accelerate over 45mph she would start to
bog down after about 1/8 mile at 55mph and if i would back off on the
throttle to about 40+ mph she was fine. so that got me to thinking about
maybe my original petcock is causing some grief. this winter when i cleaned
the carb and cleaned, etched and sealed the tank with por15 kit, i soaked the
varnished petcock and screen in carb cleaner and with some slight toothbrush
scrubbing the screen was clean, but now i am thinking that there is still some
old gunk inside the petcock that i never got out that is not allowing the fuel
to flow freely at top speed.

am i on the right track?
i saw the old posts about repop petcocks being worthless. is there any advice
on removing the screen and doing more to clean the inside of the petcock?

also if i have about 1 1/4 inch of fuel in the tank she doesnt get enough fuel
to run even with the reserve open. so this also makes me think the petcock
isnt quite right...

should i also be using an inline filter?

i am still learning on this, my first project, any thoughts advice is appreciated

thanks
