RE: Engine Mount: Bolts or Screws?
I have used nuts and bolts, machine screws in taped hole and coarse pitch screws to hold smaller engines without any problems. Currently I have a shaking Saito 100 with 6-32 machine screws taped in a nylon mount. Its holding well. Above 120 I use nuts and bolts. I run the Saito 100, OS 108, Laser 120, Webra 120, OS 160fx, Saito 180, Saito 325 and 450r
