I really think 160 is going to be too large at 4500' probably more like 145 to 150 , air gets thinner the higher the altitude so the less gas you will want in the engine. I found 160 to be too large at 1800' as have many others at or below my altitude ,so I think at 4500' they would be way too big. Maybe 155 tops. I do agree with the 45 pilots though and then adjust for best idle. Turn in until it runs rough then out until it runs rough then split the difference. I disconnect 1 plug wire and do the other cyl then switch.
You're right, my brain was disengaged...thin air means smaller mains...
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
