I don't know. But I've been running with my pilot 3.5 turns out. I followed the clymer manuals oil change instructions. I checked the oil level following the link in my previous post and had to remove about 26 ounces of oil to get it in the middle of the hash marks hot. Maybe I was too rich and there's an ass load of gas in my fuel now, or maybe it was just over filled. I know I warmed the engine properly last oil change. And I know I only put in less than 4 quarts. Either way, it ran great for the last 3 months and in the last month or so, it has been intermittently dying on me when i come to a stop. And more recently (like this morning), it idled great but I got about 150 yards down the road and It didn't want to run anymore. After taking out the excess oil it ran great again. Now I'm letting it cool down to see how it does from a cold start. And I will be letting it warm up longer from now on too. I turned the pilot to 2.75 turns, but I think that may be too lean. I guess I'll spend saturday messing with that.
