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

Re: Bendix / spark question

if the tooth in the sight plug is painted on the cc booster tooth then the cc booster mark must also be used for the chamfered tooth on the drive gear to properly time the mag internally you cannot use the normal mark on one side and the booster mark on the other....and the only way to check or set ...

Re: Bendix / spark question

IMO not a good idea to fire an aircraft engine of any kind without a prop...as far as the mag is concerned I would suspect moisture in the mag if there was water everywhere else in the engine...but check the points gap .018 is a nice gap and make sure your firing order is correct on the plug wires
