Ballarat, bit of a bumber, I'm out the other side of Melb near Dandenong. I go through Ballarat quite often and I know how far it is. I don't have any real tips, I have a basic plan I use on each one and work from there. I modify the cam,pack the cam with 3 washers and fit an idle adjuster screw in the cap. This always works with a bit of tweaking. This can be the only reason your motor will not run
