Hello,
Chris that is a kind offer, let me have another go at cleaning it first though.
I don't normally do anything different from soaking it in fuel and spraying galleries with carb cleaner.
I have done some more cleaning, jet and emulsifier are fine. I suspect the galleries. I have it soaking in fuel. I will watch the cleaning video again and read up on cleaning again. I will let you know how it goes.
I had the engine running for quite a while yesterday on choke, it is running great.
But breaking down and stalling as soon at the choke plate starts to opened.
I will put it all back together and let you know the results.
cheers
