Default Lightspeed and mag rpm issue.

So all has been great and all of a sudden i find I am tweaking my mix and not running steady rpm. Last two flights the rpm just doesnt sit flat, keep getting 2-300rpm spikes. Mix adjustment etc doesnt help. Go to altitude and try both lightspeed only and all is fine. Mag side only, all is fine. But tach when running on both is erradic and you can hear it...not just a bad reading.

Lastly, engine starting was hard for first time ever today. Hmm. Any ideas? Will take cowl off and check all wires, grounds etc...but odd it only acts up when selected on BOTH. Will also ensure key switch connections are all good too.

Anyone clever have any other suggestions......
