Both know the problem. Don has flown as much as anyone out there, and = Gene has had his 4P flying a long time. Don insists its the cowl air coupled with the restricted air intake when the alternate air system is the only = air intake. In order to do the proper test you'd have to plug the ram air induction and only use the alternate air door for intake. I believe the twists and turns of that system coupled with hot cowl air coupled with = no ram air simply does not work well. Gene reaffirmed my experience, in = ice its full rich and 20" MP to keep CHT's under 420. There may be some difference with different baffling and how much stuff is restricting air flow within the cowl. =20 With no air cleaner it would take more ice to plug things up. That = filter is quick to clog with ice. Don thought his plane worked better than = most because there were gaps around his filter, so when the filter iced up he = had some flow around the edges. Not quite the system one wants for clean = air intake, but better in ice. To your credit things work greatly better with GAMI injectors. But trust me, you engineers out there, it is a problem.
