Hi folks,i'm new on this forum,just became the owner of a '72 highwayman. The old zenith carb is running a bit rich, wondered if there is a replacement weber available new? Fitted a weber kit to an old land rover some years ago,i think that had a zenith also.The difference it made to the engine was remarkable. But with all the different levels of tune for the 1725,i guess any new carb would have to be jetted specifically for the commer? Then there's the height clearance too.Any ideas? Lots of other questions coming soon! Cheers, cyril.
