Carb gasket was changed and it ran a little longer.fuel lines were cleaned and spark plug is new.

pull the muffler off and look for scoring on the piston,the 455 had a problem with running lean from factory and burned up a lot of pistons and cylinders

It's your ignition, which you can take that stuff apart on the left hand side of the saw under the recoil. I have 2 of these, & you can get the parts. Maybe its just the magneto gap adjustment, which is like a business card or newspaper width gap. I would check that first. Hope this helps you, Rick

check crankshaft seals,maybe sucking air. most of the time the seal on the starter side. hope this helps.

The carb uses the pulses from the crankcase to actuate a diaphram in the carb as the fuel pump.If you strip the carb make sure there are no perforations/cracks etc. on these diaphrams and check too that the valve flaps are OK.if not fit a carb kit.
Also check that the pipe or channel from the carb to crankcase is OK.
If all this is correct you can simply put your hand behind the carb or inlet to check for vacuum if not there you have probably blown a crank seal(but unlikely)and you will have to replace them.
Hope this helps,and please come back if you need any further assistance.

turn both carb adj. screws out 1 1/2 turns from bottom and then fine tune them with it running. the one marked L is for low speed and the one marked H is for high speed. hope this helps
