Weber Jetting
Posted: Fri May 20, 2016 9:04 pm
Hi all,
I'm sure this won't be a new one, but hoping that somebody might be able to help me with this one.
My +2 was a cancelled Federal order in '69 and factory converted to RHD before distributed to Bell & Colville on in '70.
The engine block is the original, and is identified as a Strongberg unit.
The engine is now fitted with a Weber head and 40 DOCE 31's, which may have been factory fitted, but can't be confirmed.
I've had the car for just over a year, and part of 'learning' the car has been taking the jets out and seeing what is fitted. The car runs well, bar a very slight miss at 1200rpm, that appears to be fuel based. (ignition system all new, electronic ignition module fitted).
These are the jets fitted:
So these seem to align to the Std +2 jets listed in the info below:
However, I was under the impression that all +2's were 'SE' spec engines?
What I haven't checked is the choke dimensions or the valve lift.
It could well be that an earlier head complete with carbs has been fitted from a non +2 during its life time, however wouldn't explain the Air correct jet size.
Ultimately I want to get hold of Sprint (or equivalent) cams and jet to suit.
