OK all I cannot believe they actually sell this crudely made head, here is my cox sure start 049 and yes it fits the 061 norvel( davis head ) and with a little rc carb that was the only good thing on a little CS 61 the engine was a piece of junk from the times it left the factory, well so much for CS, Norvel seems to be getting much worse on their quality and could care less, Davis, here makes an inpeckable head and you would never see anything like this( lack of quality norvel style) from Burford or Owen down under, or PAW and others such as MVVS
my point screw it on and go no hassles no re-machining required
That norvel head takes the prize for one of the crudest piece of machine work I have seen if you want to call it that looks like it was "finished with a file"
when I get a few bucks ahead will buy an MP 061 that is a gem martin
