Re: Mag puzzle

if the engine ran ok before ya took the right mag out and now it dont after ya put it back in i bet the mag is not timed right or synchronized with the left mag...you could have a broken impulse spring but the right mag viewed from the pilot seat is normally a non impulse unit on the lycoming engines
