vacuum gauge to solve idle issue

No such luck Dar, Ill pull the top open tomorrow. Carb was new 4 years ago, but time for a look see.I bought these rods n jets earlier in the spring, a switch may be required?
Wish this happened in the spring. Winters coming, going down to -2 tonight.
Is there a buddy that'll lend you known good carb for a trial?
