Hi Scott and MF,
I jumped the gun on it because I couldn't get a murmer out of it with the starter fluid, no idea why. In the end I discovered the fuel tap would not let fuel flow through it, I could blow through it but couldn't get fuel through it, got my son to check it as well, I couldn't work it out. Then the float needle was stuck so new tested float and primer cap and it fired up. A lucky save when I had thought the worst
