Oil / petrol ratio; Casa 185

Still getting lean looking plug chops and starting to think I'm running too much oil. Read somewhere that Vittorio recommends 2%, as per standard, so intend to drop from 3.5% (finished running in about 3 tanks back but didn't know what to drop the ratio to :oops: ).

What do the experts think?

Cheers,

Dan

I'd drop it to 3% and see how that goes.

Then try 2.5%.

Personally, I think 2% is too low.
