Hey guys,
Doing a runup yesterday in a Cherokee 180, mag checks fine, pulled the carb heat, nothing. No drop whatsoever in RPM. What are the potential mechanical faults? And (stupid question time) is it possible I had carb ice and that's why there was no drop? I scrubbed figuring it was mechanical, then afterwards wondered if it was ice. Very short taxi, engine had been running maybe 6-8 minutes. It didn't occur to me to keep the carb heat on to see if it cleared and the RPM would actually increase.
ATIS was calling temp +2, dew point -10. Carb ice chart has it barely in the "light icing, cruise or descent power" range, if not just outside it.
