Got another one of these 24's fired up this one is fitted with a PT on an early F/C base. It has a modified F/C adjuster plate to take the PT and I fitted a cut down PT edger pulley with the 10mm plate welded to it ( I believe this is factory) but it was too big in diameter to fit on the 24 so I cut it down to 135mm which still left it heavier than a standard boss and blade carrier with blades fitted. It starts easily no sign of kickback and now it is a good slasher. Only downside is I can't imagine the hours I have spent on this machine but at least I now know how to set up a PT on an early base. To do these I need to get F/C slider plates and 10mm discs laser cut and then I need to find a supply of pulleys so I can weld them to the 10mm discs. Now I have to decide if it is all worth the effort
