Hello all,
When in cruise I get a vibration change that appears to come from the cowling or engine area. At times it happens with a change in power and at other times for no apparent reason. I thought I had stopped it by tie wrapping the drain tube running down the firewall and tightening the exhaust brackets and getting the exhaust as far as possible from the firewall. However the vibration came back. Just finished the annual inspection and trimmed some baffling that appeared to be rubbing the top cowling but on the first flight the vibration came back. It is more of a frequency change than a new vibration.
Anyone have a similar experience? RV-7, standard cowl, Catto 3-blade prop, IO360-M1B engine, standard Vetterman exhausts.
Thank
John
