Hi all—

I have a newly restored 46’ cub that we just took possession of two days ago. Had to adjust mags to get proper rpm’s. We went from 1800 rpm’s to now 2100. It’s much better but at altitude it’s not making anymore than 2100 rpm’s. The engine has 4 hours on it and we were running mineral oil for break in. Is this normal or should we be seeing more rpm’s?

Thanks!
