----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Jon,
Interesting comments, - Appreciate your sharing...Wonder why some engines have this problem, while others don't seem to ??? Perhaps the location of the scoop housing to nose bowl clearance ???? I often thought I would close this gap with a seal, to better create a higher pressure differential in the engine compartment, and improve cooling...But running hot has never been a problem either; --- but I never have. However I have never had an iceing/ mixture problem with my coupe for over 20 years of ownership. (except, see below). My air scoop does sit about 1/2 - 3/4 inch back from the nose cowl, perhaps releiving some of the forced air pressure.... I think from a theoretically perspective the ram air should not create a problem as the pressure is compensated by pressure on the float level, maintaining a proper mixture ( so the book says.) I did have one incident that seemed like what you describe, but it was due to the carb heat flap being improperly mounted on the carb side of the shaft. one bolt came loose, and when I hit a gust, the flap flopped up and cut off all air to the carb... Pulling the carb heat control fixed it, and the engine ran perfectly as I immediately landed. On landing I found the flap was loose - only one loose bolt stil holding the flap. Previous owner's damage to the housing had been repaired, and the flap re-installed on the wrong side of the shaft !...and lost bolt allowing the flap to flop into position of cutting off all air flow.. I quickly fixed this, placing the flap on the outside of the shaft with new bolts, and have had no further problem. This was Mom's first flight!!!!! She didn't recognize it as a problem, but scared the hell out of me!... Wonder if any one still has the Automatic Carb heat assy still operative???? Appreciate all your comments.
