timing coils and tuning carbs 1998 150 hp

Our boat is a 1999 18 ft Triton 180 Premier.
Our motor is an XR2 Black Max 150 HP.
The Serial # is B176785

We want to time and check the ignition coils to see if they are bad or good. How can we do that ? Also About the carburators. How do we know what the jets are supposed to be (what size). Well let's just ask how to overhaul the carburators and what to look for. It seems that the carburator kits do not come with much hardware, maybe they don't need much we have never had them off.

Anything else we could do to tune the motor????


thanks,

Re: timing coils and tuning carbs

First do a compression test !!!---------------------Timing does not change unless someone messes with it.-----------------------Check to see that you have spark on all 6 that will jump a gap of 7/16" with a snap you can hear.
