You are fine! Optimum A/F ratio at idol is 14:7! Now WOT (Wide Open Throttle) You reallly want to be in the high to mid 12 range once you get above 4-5000 RPM. At the lower RPM's the A/F being leaner will not be catastrophic to the engine. However if you run it the high 13's low 14's in the upper RPM range you can cause serious damage to the engine. Detonation will occur inside of the engine and you can actually hear it if it is real bad. Bottom line, it is not enough fuel.
