How did you check the pump pressure? Was motor at idle speed? Make sure it doesn't rise up when its revved up a little. It is a bit high, but a carb should be able to handle that pressure. 6 to 7 psi sounds best. As a general rule, I try to keep fuel pressure below 8 psi on any type of carb. Did it start just after the carb kit? Was the carb oxidized? What led you up to this problem? Do you use ethanol fuel? Is it after being stored awhile? If the pressure rises up above that 7.5 when you rev it, then you have a fuel pressure regulator (pump integral) problem. This could have been brought on by debris, oxidation, or deterioration.

A little help in the departments of being polite, adult like, spelling, punctuation and the proper use of English grammar would be very helpful.
