I agree B120dat wholeheartedly !!
The only pitfall is carbies in poor condition. Worn shaft bearings especially will allow them to suck air and create havoc so try to carbs you have heard running or know the history of. Once my 45's are set, they just keep on running fine. The secret is NOT TO PLAY WITH THEM ! Too many people have no idea but play anyway. get a reputable place to set them up and just enjoy them. Anyone that gives advice starting with "my mate reckons ..." should be avoided !! Good luck ... the sound of angry Webers is worth it !
