Hi Roy
The fuel level should be 3mm below the top of the jet cover (according to the Zenith manual). To check this you should take the carb off the car and rig up a fuel supply. Remove the Main jet, replace the bung, then peer down the top of the carb. If the float level is wrong then experiment with the height of collar on the float needle. The collar is soft soldered onto the needle so the needle needs to be heated to move it. Make sure the float needle is not worn. I’ve found that slightly less than 3mm seems to work best for me.
Willie McKenzie at Austin Repro sells lots of FZ parts.
However Barry’s observation sounds likely and in my limited experience the culprit is likely to be the tank. I had to remove the tank on my RK and give it a thorough clean. Rusty crud tends to settle at the outlet. Blowing back simply disperses it and a few miles later it settles around the outlet causing a blockage.
Cheers
