This may be old hat to many, but I discovered a neat looking tool at wal mart today . It is a clear plastic syringe with oil ratio mix level for gas marked for pint and quart. Have not used it, but looks like a good one for $3. "MixMizer" by Hopkins Mfg Emporia KS tel 620- 342- 7320, 1-800-524-1458. PN 310-0503-053. Got the last one.
