Thanks for the detailed post Vlad. Your oil looks nice and clean
I would like to avoid drilling my carb as it is a new machine, and I don't want to void the warranty. I think I will be using an aluminum spacer with a side feed. Any experience with those?
The coil for evaporation sounds like a pretty good idea. I might rig up something with spare aluminum heat sinks from computers. Agree it's best to stay away from bolting to engine or exhaust, sounds like a rattle waiting to happen.
Do you have brand/model preference for a low cost, bullet proof zero governor? My engine is 24hp twin Briggs and Stratton.
