I reckon your likely to scratch one up here from one of the lads, failing that I spent a bit of time on an American forum where Jacks small engines was one of the "go to" places. That's where I got my bits. Our local mower places in my area had no idea and no interest in my toys because they were too old. If it was me I'd spend an afternoon with a few beers and google up a pic. Head to the shed with a piece of wire 1.6mm at a guess and a pair of pliers. If you can't find 1.6 wire head to a welding supplies and get a length of stainless filler wire for tig welding It will be a meter long and about $1.
