1990 130ETXD goes from 5300rpm to 4500...
Just rebuilt both carbs, one was leaking at one of the needle valve.
In the process I changed the fuel pump and hoses.
Here is what I am getting now:
Idles fine for 20+ min.
From idle to WOT, accelerates really well for about 8 sec, then when the motor reaches about 5300 rpm it quickly goes to 4500rpm.
No improvement if I prime fuel, still 4500 rpm
Changed the sparks plugs with new ones and same thing.
Bypassed the quick fuel disconnect and same result.
It really sounded like a lack of fuel, however when I got home after checking the coils this is what I found on coil number 2:
The 3 other coils checked ok. Primary and secondary.

Not saying that it is the issue but this isn't normal. Fixed that but didn't have time to go for test drive.
Here is where I'd like some help. On my next trip to lake this is the plan:
- Bring portable fuel tank and run fuel from there.
- I have an extra primer bulb
- Spray bottle with gasoline , see if spraying in individual carb makes a difference.
- Going to bring the timing light.
What else could you think of I might need to troubleshoot this while on the water?
Any idea as to what the issue might be?
Thank you.

PS: Prior to rebuilding carbs, the motor would bog down from the get go and I would get a max of 4000 RPM, acceleration was very slow too. It definitively has improved since then even got 5600 RPM for few sec today but went down to 4500 rpm.
