I am hoping the fact that I can open both chokes by hand up at the carb, with the engine off, means its not this type.

YESSSSSSSSSSSSSS

Have bodged up a cable just to test the principle and the engine now pulls exactly as it should.

You know, I have had this car 3 years and only recently stated to resent the lack of performance. Its like having a new motor. All's well that ends well and thanks so much to everyone that contributed. Plenty of other ideas for the quiet winter months.

3 years and you've only ever used half throttle........ brill. Bet your fuel consumption figures increase. Don't feel too bad I once bought a lovely xflow powered westy with 4 speed box. After about a weeks ownership and out of habit I snicked it into fifth. The previous owner that sold it to me as a four speed had used it as such for 3 years although he said he hadn't done many miles in it as it was "a bit revy on a run"

Yes I'm amazed it took so long, but the performance was like that when I bought it and with the aerodynamics of a brick I wasn't expecting much different.

Spent most of the Summers cruising around sedately enjoying the views and it wasn't till the other day when it was windy and I needed 3rd gear to maintain 70mph that I really felt I should do something about it.

Having sorted out the top end performance, I now am able to appreciate what a difference has been made by installing a later (better) mechanical pump. The car now whispers along at 60mph with barely any throttle.

This confirms the Weber's desire to operate with its best performance when the float levels are maintained where they should be.
