Old Fart, don't you read the data Saito and HHQ gives you with your new Saitos. 20% oil, synthetic only for glos and you should use that red stuff Saito / HHQ recommend for your gassers. On weather, I am living in SE QLD at present with the histerical "luvvies" panicing about cyclones. As if they can influence the weather like some segments of our communities think they can. Good building weather if I could, a few more days until I can go back into the workshop and for me the sooner the better.
