GCarr Posted October 6, 2012 Author Report Share Posted October 6, 2012 After removing the carburettors, I noticed that the turbulators in each manifold revolve quite easily (GROB 2500 engine) . Should they be static or allowed to revolve ? I am in the process of trying to track down the reason for a 300 rpm loss and wondered if these might be contributing to the problem.

GCarr Posted October 23, 2012 Author Report Share Posted October 23, 2012 Thanks for the advice. It did the trick. I am now getting over 2800 rpm static. Quote Link to comment Share on other sites More sharing options...
