thanks fellas, will try the option you have suggested. Although I will need to buy a new spring I feel, as I had to manipulate the current one a little to make it work. No idea of the B&S part number though (there are so many). I actually tried to replicate the set-up in the attached pic (circled in red)as it looked "logical" but very hard to see all the parts from that diagram & how / where they fit. I get the gist of what you are saying with the air-vane & rigid wire, so fingers crossed. Will let you know- Cheers Ross.
