Roxy: It's all Connected...

So for no reason (apparently), she had become hard to start, sometimes taking 2-3 kicks to turn over.  The second clue came when the MPG dropped from its usual 75-ish down to 66.  Finally, I just took a listen and realized how fast the idle was, compared to the "putt-putt-putt" that I'd been used to.

Dialed the throttle screw to slow the idle down, ended up at 5/8 turn out - which is exactly where it used to be!

So the throttle screw, despite having the proper spring, will still move after time.  Need to make sure to check this once in awhile.

I also ended up moving the air screw to 3/4 turn out from its original setting of 7/8. 

She now starts up on first kick again, and I'm hoping I see the change in MPG at the next fill up, too.
