Hello, I have a good running Honda GX120 to replace my 5HP Briggs on a TracVac lawn vacuum. I used it this fall with pretty good results however it seems to me the rpm should be higher. The suction was less than expected (I am aware that the HP isn't quite the same however the rpm should be). My understanding is that I should be able to run this safely at about 3000rpm, however my gut tells me I am at half that. I am new to Hondas but not new to engines in general. I tried my timing...
