Update.

Put some fuel down the hole and got a wee splutter then cut out, so removed tank, and breather hose, then re fitted, and strangely it fired up

So I've just left it for now and will re fit kill switch the mora and hopefully all will be good

That explains everything!

Really ?

I have no idea why it worked after I did that just glad it did.

Just a stab in the dark was it the breather?

TBH I'm not sure, as I said, I removed tank and then hose, then re fitted and it fired up

I didn't or don't know what difference the breather hose would do ??

put your finger over the end of a pen tube or straw and suck.... then take your finger off and tell the difference

But as I said in an earler post, the carb was getting fuel ???

It'll still get fuel at idle but under throttle it'll die as it won't be able to get any more fuel as the blocked breather limits the flow.

I think there is a one way ck valve on the vent line. Add of coures you want to clean the line to insure no mud or dirt blockage.

If the bike were brought inside and warmed, there could be enough vapor pressure in the tank to push fuel through the pump. Thus your fuel flow.

If there is sufficient petrol in the tank the petrol will gravity feed through the pump hence DBFs experience when removing the line to the carb.
