Hi Sorry I ended up fixing this and it works. Don't know why I didnt receive the email when you replied.
The model is: 13069.
Serial: 130690100214
it does indeed have that tecumseh 15 on it.
Having a look at the service book linked 13069 is an ST150.
It has STG150 on the one remaining sticker on the bonnet but the model sticker is 13069 which corresponds with ST150.
No idea what the difference is.
I think the belt I have which is a B73 might be too thick and possibly half an inch too long.
I'll look through and see if I can find the belt specifications in those manuals you both have linked to.
thank you,
Troy.
