Deleted heat stove pipe?

(1/3) > >>

Toronado:
So I removed my single snorkel air cleaner few months ago
now ruff running when engine is cold.

It now is experiencing poor fuel vaporization because (when cold)
lack of help from warm air. Is there a way to fix this without going back to stock???
I have seen and
heard many many old cars with just a carb a
14 inch air cleaner run great when cold, so what do they have that I'm missing
Even my Elcamino ran fine with no heated air to carb.

How do i increase my fuel vaporization when my engine is cold?
Without installing a heated air source to the air
cleaner.

Thanks for help : )  :)

omaha:
is the heat riser valve still functioning?   sometimes they get stuck or the passages get clogged.
 Other than that, I dont know. (clogged passages are hard to unclog) OR, just wait til the motor warms up a bit, (PITA I know).

Toronado:
I will have to check the heat riser valve, Im not sure?
I definitely have to really warm it up prior to driving,
so the engines running smooth.  How does one unclog a heat riser,
because now your the second person to say this could be the culprit?
Thanks

Toronado:
The heat riser valve i believe was
attached to the old air cleaner right? I don't have it any
more. 1970 Toronado

Toronado:
if I do have one in my RH exhaust manifold than its
definitely stuck open, & guess got
to cut it out than weld new flap in WOW that a PAIN  >:(.
Oh well time to pull of my exhaust ( I replaced bolts but didn't remove)
manifold and look? maybe i can just really lube it and let it sit.
LOL
