Thanks for your suggestion Joe, I did that and got some improvement , but it seemed like I was only achieving a modest improvement after 0.110" adjustment , because I know nothing , I thought that was a lot out of the original adjustment for just an exhaust change.
So I found several other metering rods and measured them all (all were a little different) I eventually chose one and polished it down a few thou in diameter, in doing so , I tapered the step at each dia change , lovely response, smooth , modest power. Gonna leave it like that for a few days , then the camper is going back on and I can test its pulling power under full load again.
Regards
