[QUOTE="dkonrai, post: 323004, member: 9947"] it goes like this: pull both plugs pull the starter cord, three of four times. check the compression, now do the same for the other cylinder. do this three times for each hole. now squirt some 2 stroke oil and do the same, numbers should be close. a 10% variance is fine. 70 pounds is about normal for a older motor, need to know year and if its a pull or electric start dino [/QUOTE]
