Doug, altering the cam does not improve the starting, it only allows a smooth transition up and down of the lifter meaning you can control the poppet opening and therefor the revs. 90% of the problems with these motors (apart from people straight fueling them) is the float needles and it is only in the last 12 months we have been able to get the viton tipped ones and I hope to think that my banging on about the rubbish plastic ones had some part in the new ones becoming available
