Chainsaw Repair

the very first saw I ever built was a 084 , I thought compression was the answer to all questions , now this is a long time ago when the very first 084's came out . I built a motor with 300 plus pounds of compression and tried to run it on pump gas and the strange thing was it would make 4 or 5 cuts before getting hot , problem was first sure it was faster than stock but not as fast as it ended up being by a long shot second non of our races around home were cold start and I thank God for that cause that thing was a bear to start , third I could not keep any thing tight on it , it would loosen the heads bolts all the time , So I learned from that first saw that compression is not the all answer I thought it was  but also there is more than 1 way to skin a cat
