Runability issue. Minor. Question.

Just throwing some thoughts out there. Your situation might be different. A friend has a cool set-up for checking for vacumn leaks. Modified a small propane plumbers torch kit. Cut the flame nozzle tip down and graffed a small rubber hose over the end of the nozzle and put a old screw out air blower nozzle on the end of thr hose. Screw valve onto little bottle, turns on the propane and adjusts the flow with the air nozzle. You can stick the nozzle in close to the carb or manifold. Beats the carb spray method.
