Isn't the starting procedure on those (when tuned right) not touch the peddle at all just turn the key.
My YF (haven't run it 4 awhile) I think it's tap the peddle to the floor lightly once, foot off, turn key.
There's a step-like 'plate' or tab that these procedures will set the linkage on... in 5 - 7 min the choke coil (under the black bakelite cap) moves the linkage (& butterfly in the carb boar) off the step OR U can quickly pound the pedal to the floor/release quickly (or do so manually w/hood open) for leaving the curb/driving.
Hey, more info on that 'heater duct' coming from the exhaust manifold. I remember it's supposed to be mounted to the underside of the 'snorkel' to the air cleaner (there's a valve in that end too) like it is. But I don't remember it coming from the exhaust manifold. Is that correct? It's usually a silvery paper construction but this should work fine too.
Also I'd lay (bend) the hunka brake line up to the choke along the manifold for more contact/heat transfer - what do others think?
I shoulda took notes, that vid went by pretty fast.
Congrats on the successful adaptations you've made. Let's C how good it can run (i.e. next 'fixes' needed to be done to the engine).
BTW: don't trust that overflow bottle. Looks like just that, if too full/too hot it catches the overflow rather than having to go buy more. Doesn't look like the closed system style but lets C what others say.
