Title: Weber 34ICH carbs on Bristol engine
Post by: Exowner on April 22, 2020, 07:53:06

Just thought I'd pop this up again in the vain hope that it may have been missed first time around!

Does anyone have any jetting/general info on Weber 34 ICH carbs used with a bristol engine instead of the ususal Solex set-up?
Any info gratefully received.

Glen,
I recall some Arnolt users of this carb. Sure Barrie Bird discussed this with me as an option for my Bristol 400, so may be an article or two in the old action  magazines.

It did remind me of some info so here’s what I found ( jetted similar to solex)

I fitted these Weber carbs to my 100D2 engine in 1985, to replace the leaking and worn standard Solex units. They were supplied by Chris Montague Carbs, set for Bristol engines. They bolted straight on using the standard Vokes air filter, fuel connections had to be modified. I recall there were some initial jetting problems and I got advice from Barrie Bird. Since then they have been fine. I still have the bill for the changed jets but unfortunately not the exact description. Barry may still be able to help.
