First - what a GREAT site; I've read many messages already and have gleaned an insurmountable amount of information that has already greately benefited me.
I rebuilt carbs on both; drained fuel tanks; then changed to pre-mix system on both with block-off kits.
Running, one runs fine and starts easier than before; Second has issues.
Second will bog down on quick throttle up, but only after running for about 30 minutes, then I must slowly ease throttle up and then, all of a sudden, it will take off. It also may all of a sudden die while slight throttle (just above idle) and then be a little hard to start.
Performance Q's: Second would not plane (I'm 290 lbs) until I removed stock carb air box (but then after I hit wave - had power loss and would not plane anymore). Obviously, I had better air flow without this air box on, so . . .
Question: Can I replace this air box with something that will produce better performance?
In addition, as they both sat for a while, should I replace the impeller or check something else to determine if something else needs replaced, etc. that would give me better performance?
