So It's a little hard for me to get parts here in south africa don't have a local import store for it and when I have ordered from overseas they tend to get lost or stolen.

Have you tried to keep her running? I only found out about the temp Parr once she was running got a bit and I could hear 1&4 start to fire here and there. Then a huge backfire shat Myself and she was running fine
