Suzuki 60 - 2003 - loss of power!!

Hi All

Can you help?

My engine is not firing on all cyclinders, well, that's what seems to be the issue.

What should I check first:
Plugs
HT leads
Fuel

Hi

after the sparks check fuel lines and filter, check HT leads, if that does not help clean carbs. oh and I am taking it for granted that you battery is ok.

good luck

Dave

A cracked plug was the cause in mine once. When was it last serviced?

You are looking for a needle in a haystack!!

We have a similar problem on a Yamaha 75, bottom cylinder not firing, we checked everything, plugs, coils, leads, wiring, CDI unit, compression test, reed valves, carbs stripped and cleaned and we STILL have a problem! Powerhead off tomorrow, suspected crankshaft seals.
