Hi all

Just posting this for future reference more than anything so it can be searched for if needed.

I’m in the process of rebuilding a zenith carb and noticed that the top cover/choke section was missing the ventilation screw/jet which forms part of the economy device. Apparently this is quite common as was removed to lean out a rich running carb instead of dealing with the body warping issues?! I searched high and low for a replacement (LR Part No 90601898) but all retailers ‘out of stock’. I phoned www.zenithcarb.co.uk and they have a good stock under their own part no 016353/3.0 if anyone ever needs one in the future. A very helpful and knowledgeable parts team!

Hoping that my rebuilt zenith will be an improvement on my Weber

In many years gone by I did use the 36IV for other uses other than my Land Rover.
I had one on my 1300 Escort.
Experiments with different jets had me a good cheap power up grade [along with other tuning] over the original set up.
