That’s very useful Brian, thanks. As it happens the body is aluminium so all very interesting. Float height is in the right area. I quite agree about the large bore, I’m surprised that it runs so well at low speed, prob the rich mixture. It doesn’t spit – yet. I’ll probably fiddle with the slide in the knowledge I can ditch the whole thing and start again if necessary. If you have a 289 slide I would love to know the dia.
