I just ordered the carb kits and impeller for my Ev 90 V4 and will play around with it this winter. I will have to change the fuel lines and filters and maybe the fuel pump but it should be good to go by this spring.
Does anyone know what the compression should be in each cylinder? I bought the service manual for my 1984 motor and it covers all the 1984 models so finding some of this info is difficult.
When you change out your fuel lines, make sure they are Marine rated. Reason being is that they hold up better with the oil mixed fuel. Normal automotive fuel lines will become ghard over time due to the two stroke oil and gas mixture running through them.

Gamalot,
As far as the compression on my 1992 88SPL they're all 125PSI. I think the more important thing is that they are all the same. Good luck.
Thank you! 125 + or - 5 PSI sounds like a good starting point. I wore my eyes out reading the repair manual and never did find what the compression should be.
