Can't get fuel to float chambers

But do it with the float bowl off.
And make sure the float drops away from the needle.

I'll give that a go tomorrow and report back, thank you.

There are spring loaded pins in the end of the needle valve which need to be free and the tang on the float has to only just touch the pin when floats at correct height.
The givaway is you say it ran but when you checked the floats were out by a lot

Almost certain this is the problem now. I'm in the middle of a complete carb stripdown and nothing is blocked, the insides are in really good condiiton so I guess I set the float levels too low with the end of the needle valve slightly compressed. Thanks for the great advice.

Set the float heights correctly this time, started her up and she purrs. Beautiful.
