Webers. What type?

Your aiming for roughly 14:1 at most situations though allowing for slightly richer flat out to compensate for rising temperatures and loads (Its not a replacement for an RR but it will get you to within a gnats so final tweeks on a road wont cost a fortune in time.)It takes a bit of getting used to as its real time readings so the slightest change of throttle position or load shows up immediately but if you know what to change and have a few spares with you then you can do the change there and then and see what the difference is. Ive had great fun with it on mine when retuning for the larger pistons and other engine work.

Interesting!

more a religion than real reasons for or against DCOE.

There are about 135 different DCOE ex works ever built and most are

for four cylinders and from that the first goal must be to get three similar carbs.

 

Many things can be swapped but not the progression holes.

They should be same number, position and size.

 

Rest is more or less some work and spending a lot of money for jets.

As nearly all can be changed all must be checked otherwise its not good.

From that point it might be interesting to buy 3 Chinese DCOE, never did so

and never heard anything about them.

 

Would start getting engine idle with mixture screws open in proper turns. Say that because not all

require 1,5revs, there are also those setscrews with different cones availiable. Than going on with

a wideband controller maybe Innovate setting full load AFR to 12.7. Between test drives checking fuel bowl height.

 

All in all EFI is much more comfortable and cheap to set up but requieres more skil to fit compared with DCOE

Just from the power there is not much difference, but that will rise with small venturis to get a better daily driver.

Mine had 32mm venturis and engine will stall when opened up at 2000rpm, needs a skilled driver.
