The rope on the 1645 mechanism broke - to the recycle. I actually got the 1610 started. Now I have to get some gasoline lead additive-no unleaded for this beauty. 16 - 1 gase-oil ratio - that's really old.

mvron: The 36 cc.1610 was introduced in 1977 and the 69 cc was introduced in 1969 . My Uncle had a 1645 Model . It was a rather stout unit made in British Columbia Canada. I would not sweat the Unleaded Fuel since your dealing with a two stroke engine , no valves requiring protection . Just ensure a preimium grade oil . I would run synthetic at 40:1 Ratio. I run 50:1 Amsoil Sabre Syn oil in both my Vintage 1967 Pioneers .

Thanks for the tips ewalk. I've got some really good Echo 2 stroke oil that should work. Good idea on the fuel also.
Having second thoughts on scrapping the 1645. Will look into the rope problem further.

Echo Oil would be great ! Have fun with the Old Girls :) .

I have a Skil 1610 and am in need of an ignition coil. I can't find one anywhere. Does anyone know where I can get one?
