I recently purchased a 1994 Yamaha ProV 115 and it ran great first 4 or 5 times. Now after after the launch start, idle through no wake, and 1st run the primer bulb wont get firm and i have no power when trying to take off and get to plane. Primer bulb gets hard the 1st time before i launch. It will start decent 4 outa 5 times but still doesnt sound quite right. I can idle but as soon as i crack the throttle she dies. If i feather it a good bit it will finally open up and go. I have been running a 50:1 mix and the precision blend system together until im sure the oil pump system is working. Finally just too much oil being run through it or a primer bulb/ fuel issue? Any thoughts would be appreciated.

I should mention that after the first time it did this i checked compression and were 115 for all 4.
