Got this back from the supplier, If I read this right, they say the later for high altitude makes it run richer, well higher you go theres less air so need a smaller jet to run weaker,and this engine runs weak at hight speed 3600 rpm and rich at idle to half throttle. so main jets would be of no use.

Honda engine parts lists usually give you three different jets so you can finely adjust the fuel amount – Briggs only offer one standard plus one high altitude jet – the latter making it run richer. So the only thing I can suggest is maybe trying the 16hp jet:
