200 black max no power

[blackbeard]

Hi all, my mates got an old 90s 200 black max. In neutral she revs up ok but sounds bit sluggish. When put into gear its got no power at all..
Carbs are clean just put on new rectifier as taco wasnt working
Any ideas,
Many thanks

If you squeeze the primer bulb does it stay squashed ? if so you have a blocked fuel filter we had this problem last weekend

Sounds like a coil to me or maybe a bad earth on the switch boxes.

You should also set the timing now. just FYI switch boxes should be replaced in pairs. If one has gone the other probably will soon too.
