1989 SP Carb main jet help

It has been about 20 years since I worked on one of those round body carbs but if I remember correctly that jet is not replaceable. We used to drill them out with wire size drill bits but once you do there was no going back.
With a stock ski if everything is correct there is no reason to mess with the jetting.

There is a problem, at least I think so.
The ski runs really well, lots of power getting going, lots of fun.
But when going straight and fast with the throttle a little over half, then quickly giving it full throttle. Not much happens. There is no bog, no engine sputtering, nothing bad. It just does not go faster.
Any I have been lead to believe there should be some acceleration in the upper part of the throttle.
I have not looked at the spark plugs (plug chop) at full throttle. So I don't know if it is getting lean. Nice healthy plugs at the lower throttle.
