seller is paying for parts, im doing labor to be nice since he is a family friend and i dont mind it. only failing numbers is idle: 363hc max is 250 @850 rpm max is 1000rpm and 2.67%CO at 2500rpm max is 2.0%. i completely forgot to replace the air filter so i did that today, and tuesday i will turn the idle up a bit to see if i can drop the hc's. any other ideas? all i can think of now is carb rebuild and O2 sensor, my job is motorcycles so all these numbers are all greek to me, except i know what hydrocarbons are lol
