the Blendzall green label is the best for these comers and the 87. but you're not running enough oil, 4 oz to a gal. is great for your weedeater. Comers like 8 oz / gal. under normal ambient temp. If its cold out you drop to 6 oz. if its good and hot you can get up to 9 oz.
The more oil, the leaner the air/fuel mixture. The leaner you get the hotter that little comer runs and they like to run hot. If you get it to lean when it cold out it won't take off.
Start with 8 oz / gal. and adjust with your carb jet to get the spark plug looking like coffee with cream. black plug go to a smaller jet, white plug go to a bigger jet.
Rich is stronger on low end (but won't wind out), lean has more top end.
