Does it have electric solenoid in the carburetor base ?
Is this OHV engine or the older twin flat head?
If it has the electric solenoid, did the old carburetor have the same? Remove the old solenoid and remove the inner ti, and install it in the new carb for test, with it as a dummy.
I stepped away for supper, sorry. The thought on the solenoid is that it may be loosing voltage, and when it does it momentarily cuts off the fuel.

HI, my name is***** will try to assist you.
I want to take you in a different direction since the engine is doing the same thing as it was prior to everything that you have done.
In between the two ignition coils is a ground wire that kills the spark when you turn the key off. In this wire are two diodes, one in each lead of the wire. I have seen one or sometimes both of these diodes go bad which will allow the two coils to begin to misfire which is what I believe that you have happening. You can check the diodes with a voltmeter to see if they are good or not. You should have continuity or if doing a diode test with the meter you should get a beep in only one direction when checking the diodes. Place your test leads of the meter on either side of the diode to test, then on the same diode just reverse your test leads to the opposite sides you should only have a beep or continuity in one direction. If you have in both directions or none in either direction then the diode is bad and will need to be replaced. You can purchase diodes at a store like Radio Shack or you can replace the entire wire assembly by purchasing through Briggs and Stratton.
Thank you it has been a pleasure to assist you.
