Hi Brian You dont have aproblem really .Just a normal thin with achainsaw chain It just needs alitaken out. Bit hard to do unless you have an anvil to supprt the chain while you punch out therivets Your chain may have equal number of cutters on each side. It does not matter at all but when you have shortened it it will have one cutter short one on side. . Best take the chain off and take to a chainsaw shop as it will need a new joining ink to join it back up. IF the shop does not have the correct size pre set tie strap for the chain then ask them to punch out the link ans give you back the 2 tie straps etc and the plain links . You can join the chain up again using the old tie straps etc but you will not have a great deal of metal to rivet over but it will get you going again till you can buy the right new tie strap. . Will look in here again . BTW I have the gear to shorten chain etc which I can give to you Cheers Joe Brown
