Hello I have an older craftsman 2 stroke 2 hp snowblower which has a Tecumseh engine in it but since It is old there is no user manual or any info. What I need to know is what ratio and what type of gas should I mix with fuel because there is no ratio or anything on the gas cap. I would also like to know where I can see a manual online because I can't even see picture status of my unit so I am asuming this is pretty rare because I think most of them had the 3 hp because it had more power and electric start.
