One other problem I had was identifying what model of Clinton engine it was. The plate with that information is missing. After a bit of research on the internet I found it stamped in the cowling it just needed the paint carefully removing. I now know it is a 498.
There appears to be a problem at the moment causing an error message ‘file not uploaded’ to appear when trying to post photos. We are looking in to it to see what has happened.
I wondered who had bought it. Did the seller give you the following information? 350309 was delivered on 5-3-1957 to J L Blakemore, Plascyni, Berriew. Let me know if you need anything like owners manual, parts book etc. I will see if I have any side panels in my spares pile.
Before starting ensure machine is in neutral and tines are disengaged to avoid any accidents. Turn fuel on, tickle carb, open throttle a bit then wind starting handle. If engine has not run for some time it might be a good idea to check for a spark at plug before starting. Once engine is running check for oil flow as said by hortiman.
