well, it came down to either the 2.5r, or an O.S. .18
the reason i went with the O.S. was becasue i called the guy at my LHS and asked him about the O.S. engines, and he said that they r much better engines than the 2.5's. he said they run better, cooler, and last a long time. i've heard that from other people as well so, thats the reason i went with one.
P.S. i went on O.S.'s website and looked at the TZ on there (mine is not here yet), and it doesn't look like u can get a pullstart for them, so that means i need a starter box right? can some one provide me with a link or a company name that makes starter boxes that will work with this engine? thanks
