thought it was fixed now back to it's old tricks
having an issue where the ski will start and idle really well BUT will not behave above idle. when taking the ski out, it will idlle out past the no wake zone then when you go to give it throttle it just sputters and pops and will not rev any higher. some times the ski will have a moment of glory and get going (all be it rough sounding) up to around 30-40is for maybe 30 seconds but then sputter back out and go back to idling or sometimes die.
this ski sat in a garage for 4 years before i purchased it.
things that have been done to the ski:
ALL 100% STOCK
FUEL:
pulled/drained fuel tank
replaced gray lines
cleaned selector switch
rebuilt carbs, used OEM mikuni kit from OSD marine
pop off checked out at 32psi each carb
fuel pump gets fuel, lines are always full when poping taking them off the carbs.
plugs are a dark wet black, slightly oily
needles set to 1-1/8 on the low and just cracked open on the high
ENGINE/EXHAUST:
compression is 138 mag and 150 pto
cleaned rave valves-verified bellows are in good shape
no visible exhaust leaks
ELECTRICAL:
this ski has been jump started from a running car when i bought it. (AHHH-was a n00b at the time, have not done it since)
the ski did start when jump started, there was no battery in the ski when jump started.
mpem gives 2 beeps and recognizes the key.
mpem shows correct resistances (for what its worth)
all gauges other than fuel work correctly
NEW battery, starter spins quickly and strong.
NEVER had a blown fuse in front E-box
the ski has spark, cant tell if its blue or orange, need to investigate further.
ground on rear coil looks like this:
alright that's what ive got so far, READY GO!
