I think I bought this back in '92. Almost everything is original. I took it to get serviced because it stood still for over 11 years and I think they replaced air filter and try to fix pull-start but couldn't find a replacement. Just this week, I took it in to see if they had a pull-start. No luck but there was a original replacement on ebay. Bought it and Hobby shop mounted it for me. They tried to start it but were afraid to break the new pull-start. They told me to bring it back next week when they get their hands on a hot box.
