It's ok I learn a bit from every response. Finally decide to go for the webers with the small size malpassi and my new pump and new rod retained. Will play around with the solex carbs which I earlier refurbished but I think the injector is broken on the main carb.
Ok, I've also decided to stick with my Webbers and get them re-jetted and tuned by Mike at Wayoutwestie, I'll post how I get on..... Thanks
