Grumpy Posted February 5, 2006 Share Posted February 5, 2006 I have recently bought a 1950's Allen Scythe. Can anyone tell me if these will run adequately on unleaded. If not, what needs to be done so that I can run it on currently available fuel? Many thanks, Steve. Link to comment Share on other sites More sharing options...
Jc Posted February 5, 2006 Share Posted February 5, 2006 Is it 2-stroke or 4-stroke?If it has a Villiers engine,it is likely to be a 2-stroke which will run happily on unleaded with the right amount of oil added-Villiers of that age ran on 16/1 petrol/oil(1/2 pint oil to a gallon of petrol) if I remember rightly.

Grumpy Posted February 5, 2006 Author Share Posted February 5, 2006 Thanks for the reply Jc. It's a four stroke. Link to comment Share on other sites More sharing options...
bedders Posted February 5, 2006 Share Posted February 5, 2006 As a generalisation i would say that hardly anything of that vintage would be happy to run on unleaded in the long term. It leads to recession of the valve seats. Remember that in those days lead was added with gay abandon and engine manufacturers hardly needed to give valve seats a second thought. There are however 2 ways to overcome this, 1) is to install hardened seats (expensive) 2) is to put an additive in with the petrol. I use Castrol valvemaster in a car and it works. Hope this helps.

Grumpy Posted February 6, 2006 Author Share Posted February 6, 2006 magic - thanks bedders, that's what I was after. I'll go and search out some Castrol Valvemaster!PS - just looked at the Castrol website - looks to be just what is wanted. Thanks again! Link to comment Share on other sites More sharing options...
