Moped Army

I'm also using a 7, with a 40:1 mix, 88 jet/15mm bing. I still have one airleak between manifold and carb, mine doesn't foul but is probably close to it because the plug always looks very dark.. mine is behaving a lot differently after about 20 minutes of riding, it starts idling lower so i have to screw in the idle, and sometimes bogs. I'm thinking of leaning out my needle. first things first need to get an o ring for that air leak. so far i am loving the kit though.
