How do I replace the carb mount on a Cox TD .049?
The aluminum retainer just behind the prop drive washer has to be unscrewed (c/clockwise) with the Cox wrench. The spanner on the wrench engages in the 2 slots....just screw it all the way off and the drive washer is pressed off in the process. The plastic frt. hsng. will then pull off. Put your new hsng. on, put the thrust wshr. and the drive washer on, being careful to align the grooves carefully; then press the drive wshr. on with a prop and the prop screw. I like to tap the screw with a small hammer after the screw is fully tight to seat the drive washer. An allen prop screw helps to get it tight enough. Comprende usted?
