I have cleaned and set up the three carbs on my Sport Jet 90 and when I bought it it had plastic floats in the carbs that have no way I can see to adjust the level.
They are all a little too low (or too high when held upside down).
The plastic floats have plastic tangs that as far as I can see and try if bent just pop right back where they were.
All three are the same.I read an article where a guy has problems getting full power with these and he put his old metal floats back in.
I was having problems getting 5100 rpm in the boat, but a redo of the ignition took care of this, but I have a slight miss at full power.
By the way I updated the ignition with CDM modules off a late model 200 hp Mercury and a 50 HP three cylinder harness and dropped the switch box and adapter etc in the storage bin.
The Motor had the red stator coil so that was compatible. I also had to change the trigger as one cylinder was not getting a pulse and the resistance test was off.
Now who knows about the floats?
