Secondary Hanger?

<< < (2/2)

Toronado:
Thanks cliff,
 today i made new adjustments,
Air flap at 1/2 from zero tension.
removed & bent hanger up slightly made a trace to measure difference.
increased accel pump rod travel for larger shot.
Tested pull off at idle held tight and closed, turn off
car and it open like a vacuum drop. Now Im
going to test drive it, be back with report.

Toronado:
After adjustments came back, &  no more
bog, popping or lag when floored as secondary open
up. Thank you Cliff, bending the hanger up really
helped my momentary lean condition as sec open.
I also think increasing my accel pump shot
helped I drilled a higher hole in the linkage
for a larger shot of fuel i could see the increase of
fuel in the shot after drilling.
Forgot to mention using AU rods & M hanger (going to buy DA rods)
most likely stock like every thing on my Toronado.
Ah Toronado's are the best...

Cliff Ruggles:
The primary side accellerator pump is also a KEY player in secondary transition, which I forgot to mention earlier.  It is still putting fuel into the engine when the huge secondaries open quickly.

I cured quite a few secondary transition problems over the years by installing one of our modern HP accellerator pump assemblies.  They improve pumping efficiency, especially on the older carburetors with the old style pumps that lacked the garter spring and better springs.

If you don't have one, I'd get one, they are available directly off the website separetely from our kits.....Cliff

Toronado:
Your right mine has no garter spring,
 & I've been meaning to order the HP
pump + DA rods. Eliminated problem with my modification
but not as well as it could with correct parts.
Today Im going to decrease spring tension
to 1/8 turn, because they seem to close to early
with 1/2 turn at high speed vacuum drops & the spring
pulls them closed too early (thats what it sounds & feels like).

Thank you Cliff, it's incredibly educational & valuable to get your insight.\
My car would be a laughed at dog without your help.
