I bought one of those low compression ones must be 8yrs ago now ...a victor .....four stroke .....have only changed the plug and blades once .....other than that ...I prime it 8 times as per label on the side ...put the throttle too half way .....and pull the cord ......it has started first time every time since new .......the more bits to fiddle with the more chance of something going wrong I reckon.....besides .....yankin the cord is good for "upper body " developement![]()
