Truck carb jetting 70front 73 back power valve is 6.5. U need to bump it up I'd put 80front and 84 in back and a 7.3 power valve and it will run great for a boat great price.

Not sure how you are recommending jetting and power valve size without knowing on what application this carb is going on.

I haven't checked to see what stock internals call for in the book, and further... I have not checked what is actually in the carb.

Simply said, your comment/suggestion seems right about useless.

No need to apologize, you did not burst bubble...
Just trying to help you understand that you can not recommend any "tuning" tips without knowing the intended application.

A better question, "to let people know" would be:

Are carb internals stock specs??

I will check tomorrow what is actually in there.

Good lookin' out 👍
