My fater recently acquired a 1992 Toro CCR Powerlite snowblower with a Tecumseh HSK600 engine (3hp, 2 stroke). It starts on the first pull (if you prime it properly) and seems to run strong.
With the previous owner's oil gas mix it would smoke on start up, but I beleive that owner mixed his gas with extra oil as opposed to Toro's 50:1 recommendation. I'm not sure what brand was used.
We started using Amsoil Saber Professional mixed to 50:1 (we were a little affraid to use Amsoil's 100:1 suggestion as this is the first 2 cycle engine we have owned). There is no more visible smoke on start up or during running, but the Amsoil hasn't done much in terms of reducing exhaust smell.
Is there anything we can do to reduce the exhaust smell?
I'm thinking that reducing the ratio of the Amsoil may help. Is running Amsoil leaner than the engine manufacturer's 50:1 recommendation safe on a 16 year old engine that has some carbon buildup (visible through the spark plug hole)? We were thinking of bumping it up to 60:1 when the current mix is used up, but I wonder if it's too small of a change to have any effect.
Any other suggestions?
