Hey Gents -
I've been chasing a WOT engine roughness and few hundred RPM drop on climbout in my J3 with c-90 ... Carb heat makes it go away as well as pulling the power back ... I tried plugs, drained and cleaned the gascolator as well as checked screen in carb. I also pulled the drain plug on the carb and got what looked like some metal shavings out of it. After some reading I checked the Throttle shaft and there is some visible play in it on the port side near the accelerator pump. See 5 second video here -
... Thoughts? Looks like that could cause a lean condition at WOT?
So I'm thinking it's time to send it off or replace with overhauled unit. I'm just outside Toronto, Canada ... who is the go-to shop? Plane is experimental btw.
Thanks!
