Has anyone had problems/experience with the truck avenger? Mine has been a
real pain, during initial startup and warm up the idle is smooth, constant
and set to the required specs when I put a load on it (more than 1/4
actuation of the throttle) the engine wants to stall then I let off the
throttle and it runs normal until I put a load on it, now after driving for
more than 10 minutes it does get better but still will stall if I romp on
it, even stranger is the fact that when I park it and let it idle the curb
idle is way too high. It also appears to be really excessively drinking the
Holley fuel pump
Weiand intake 8004
Truck avenger 670 cfm
new bosch +4 plugs
"that's all the tricks"
manifold pressure is 15
primary and secondary floats reset
air ratio needles reset
timing is right on
choke "hard to tell"
*ear to ear*
good to know I'm right every once in a while...
I decided to look it up, according to my Haynes book:
300CUI @ 6500RPM is 450CFM
But he probably wants top HP at more 4000-5000RPM so..
300CUI @ 5000RPM is 315CFM
What are your thoughts? Allot lower than both of our WAGs...
Th e general consensus, and i agree 100% is that you over carbed that 305
I researched the truck avenger and it is a single-line dual-feed square-bore
with vacuum secondaries.
Step 1: Install a stiffer spring in the vacuum canister that actuates the
Step 2: Remove the primary metering block and reduce the all the jets by at
least 2 sizes
This will drastically improve driveability, but more fine tuning is
Carb. tuning is a art form and requires much trial and error unless you want
splurge on a air/fuel ratio monitor which will greatly simplify the tuning
Short of buying a smaller carb. such as 450 or 500 you're gonna have to do
rejetting: the idle circuit, metering block, main jets and vsecondary spring
modifications to work correctly on a motor that small.
Heres a idea, put some cubic inches under the hood.
There is no replacement for displacement..........
BTW, are you a Ham....those look like call letters
