Eric,
Tony Coopers details:

He does not do email or have a website. I have had three mags done by him and they have been spot on and at a very good price. He regularly deals with folks all over Europe.

Cheers

Thanks again everyone for your replies,
I’ll give Mr.Cooper a call and we’ll go from there.

With regards flooding,

I’m running the bike on an AMAL concentric carb, runs great and I do have the decompressor all intact.

If it was flooding (as some people suggested) wouldn’t the plug be wet with fuel when I remove it? Mine isn’t, just a little black with carbon but not wet.

Didn't know you had a concentric on there.. which is much less "floody" than the original fitment pre-monobloc.
My pre-monoblocs just decide to flood on their own sometimes or once flooded just take ages to sort themselves out. I think it's been said here before that the float system doesn't always get the best seal on the float needle.
The pre-monoblocs are also preset with regards to the float height and rely on the right thickness union nut, washers and positioning on the float chamber (there are different angle float chambers as well) to set the right float level.

Concentrics are better, but the float level still has to be set right on them.

They all work well if put together properly, but the original responds a lot to leaning the bike when starting. If you are on it and leaning to the left you must tickle it when starting. I've NEVER had a better starting bike than my W/NG. It usually fires first compression, not just first kick. I'd like the top feed bowl. I'll do one when I get around to it .Nev
