before I start re ringing Ive a couple of questions...
firstly looking at Roy Bacons book the cylinder head for a 1952 plunger A10 should be 67-1065, mine is a 67-1066 any difference??
second, bore with new rings have 0.015" end gap is this right/ wrong as cant find spec at the moment.
thirdly , Draganfly have sent Gandini rings. are these ok, or not?
fourthly , having just rebuilt an ariel square four motor on standard original pistons the Gandini rings wouldnt fit in the bores, after much cussing and phone calls its established the inner diameter of the rings is 0.020 smaller than standard/Hepolite ones, will I have a problem?
reason for asking is that the square 4 caused a lot of trouble and if I dont need to re ring or bore then Ill keep them until I do unless I am going to get trouble fitting them... Gandidni aka GPM, thanks
