Re: Bluetooth O2 sensor and a carb

Today I got it up and running. It works exactly as advertised. My steady cruise is solidly in the 14's. It's hard to be exact at any given moment because after the decimal, the AFR is bouncing around quite a bit. I saw it bounce occasionally into the low 15's as well as the high 13's but as an average the engine was cruising at about 14.5 or so. Foot to the floor got me to high 11's and my idle was rich, in the 10's. I adjusted the mixture screws and got that into the 14's with a few bounces to the 15's upon deceleration.

What do you guys think? It seems to me like I am well within the ballpark. I suppose seeing things more into the 15's at a steady cruise wouldn't hurt but going up one rod size on the primarys may just be too much. I dunno. I'll get some more behind the wheel time with it to get a better idea over a wider range of conditions. Could I also anticipate it leaning or enriching itself as air temps change. Today it was mid 70's outside
