I thought I saw it someplace that with the new tcw3 oil I should run this at a 24:1 mix? It calls for a straight 30 weight at a 16:1 but with the modern oils 24:1 would be ok? I just finished going threw this with new water pump, carb kit, and points, plugs, condenser and coils. Ready to fire it up after 20 years or so now and want to get the fuel-oil right. Thanks for any info. Jim
