Sorry but I just use a tuning ear to set em up and not very scientific
really but at 28 mpg it seemed about right.
As it was a Pinto if I had killed it it would have been a kindness (I hate
Pinto's).
You can always put a lambo sensor in the exhaust near the head and connect
it to a voltmeter and although I do not know the exact figure I believe its
14 volts if the mixture is right, but that might be the % of the mixture.
I was only playing with it and when it ran well I left it.

Sounds like my sort of money - i.e. as little as possible...!
What always concerned me was how to set up the jetting without a
rolling road? How did you overcome that?
I did once hole a piston on a bike that was running weak, so I'm a bit
nervous.
Although, given the chequered history of this particular engine, I'm
not sure how much I trust the jetting in the current Weber anyway?
Head gasket looks pricey at present, Either Felpro at Ł40-ish or
Cometic at Ł90-ish. Standard one is apparently 82.8mm bore, which
would protrude 0.1mm into my 83mm bores. Wondering if I would get away
with it?? Felpro bores are 86.7 mm, which worries me with regard to
the amount of material left between the bores, and Cometic look like
the K-Series gaskets that caused so many problems for MG Rover. So the
standard one might be the least risk. (The piston stroke stops 2mm
short of the top of the block).
I could have measured the one that came out, but I'm not home again
until the weekend. Again, any experience/thoughts would be
interesting.
Dave.

Hi Dave I cobbled up a set of Kwaka XR6 carbs (Keihlin) on my Dolly sprint
and got them to perform as well as the Dellorto 45's that it had been on,

I used them on my Robin Hood pinto boat anchor engine and they were fine
and
I sold the car with them on.
I made my own manifold in alloy and got a local welder to weld it for 60.
I would get a set of small drills and gradually open up the jets till they
suit, I was lucky and found that 1.8 mm was perfect and bought them off
the
bay for a fiver and the carbs I bought several years ago before they
became
famous on car engines so only paid 12 for four 38 mm as new carbs.
I have no idea why people struggle and spend fortunes tuning Webers when
these carbs are so good and simple, one word of caution though Webers and
Dellortos like up to 3.5 psi fuel pressure and bike carbs much less and
about the same as SU's at no more than 1.5 psi or they will flood.So do
use
a pressure regulator.
Good luck.

Well, they reckon it's one of their Stage 3 engines. Certainly, a
search on Google throws up plenty of forums with people complaining
about them. We'll see...
Just down the road from me are Bogg Brothers, who are well known for
bike carb conversions. The car came with a set of R6 carburettors, but
no manifold. I'm idly wondering whether it might be worth looking into
how much would be involved in fitting them. Any comments?
Dave.
