Rotax 582 Magneto Drop

by E Franklinraj in 2 Stroke Technical Questions 3 years ago

In my Rotax 582 Engine One side Mag drop is 300, the other Side is approximately 1000 rpm

The starting and full Power is fine

I tried switching the bottle coil, carburetor, Stator coil but still the problem persist on the same side

TDC, Pick up position, compression all found satisfactory

can someone identify, What Im missing to verify

Thanks in advance

Regards

E Franklin

Spark plugs. Try swapping them, see if defect swaps. I had the same, that was my problem after 14hrs from new! (Blue top plugs are prone to defects!) - If not the ignition system needs checking as per the manual. - leads, connections, circuits etc.

Does the rpm actually drop that much? Does it sound different from the good cylinder? Some tachometers do not read correctly during mag checks.
