The description points to carb Ice, but you pulled the carb heat! So, is the carb heat butterfly working?Wayne Woollard----- Original Message -----From: Don MackSent: Sunday, September 21, 2003 11:04 AMSubject: [COUPERS-TECH] Short RPM drop----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----I have not been able to fly for 2 months.I went out last Thursday and flew around for 1.3 hours without any problems.Today, about 10 minutes after takeoff RPMs dropped from 2500 to 2100 for about 15 seconds. Temps in mid 50's, humidity in the 40's. I returned, landed, did a mag check and all was normal. Felt each cylnder and all were hot. No leaks, etc. I went and flew around the airport for about 1.2 hours without any problems. Landed and a nearby airport and got fuel.On my return to home airport (about a 10 minute flight), same thing happened as I entered crosswind. I pulled carb heat and did not notice any difference. I flew a high downwind, pull back to 1700 and all was fine. Ran full throtle for about 20 seconds and all was fine. Landed without any problems.I will give John Sr. a call tonight and have a local IA to discuss it with, any thoughts would be appreciated.don mack[EMAIL PROTECTED]============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
