Hi!
I´ve got a 93mod Yamaha 20HK DMO Autolube with a problem with intermittent fiering/missfire. When testing it in idle it missfires with no special pattern. When testing it in gear the engine missfires more and is not able to gain rpm.
Video of the engine:

I´ve overhauled the carburators but still have the same problem, suspect that it is an ignition problem but are not able to locate any failure with the system.
The thing that I have no control over is the ICU, type Hitachi TIA02-19(Yamaha 6L2-10).
Does anyone have experience with this engine and this type of missfiering?
What kind of symptoms can the ICU give when it is faulty?
Whould be very happy for any response/tips about this problem
Thanks in advance!
