hi guys, I have a 140hp aeto which is driving me crazy. Cold start is main issue, if it doesn't start straight up its a mongrel. Checked choke operation, ok Fuel supply to carbs, ok. cranking speed, ok. I have no voltage @ coil packs until it starts??. CDI changed 3 yrs, fuel pump 2yrs, regularly serviced. Other issue is if idleing for2 to 3 min stalls as if ran out of fuel, restart with choke. Once started and running can ski all day. HELP
