Jon , did you turn the mix screw all the way in(seat it) before you brought it back out the 2 1/2/ turns ? and only 5 mi. at 37 degr. is not enough time to get it good and warm. mine would require some choke usage still at that point. the mix screw is spring loaded so it seems to turn hard, just do this firm but gentle. maybe this will help.

 

You might want to read the last 7 or 8 paragraphs at the end of this page for the proper adjustment procedure.

Another good source for carb tuning.

the importance of reading directions completely.

 

the ride home was shitty, but a couple turns at home and I was golden.

 

glad to hear you got it , was it that it wasn't seated prior to the turns?

 

It was in too far. TOO far.
