RE: MVVS 120 boxer engine
I think Sparkey has no idea how to behave when writing in public. Maybe he is ignorant of forum rules in general as well.
FYI Sparkey: Dar provides better support on glow engines than most of us here. Those 60 years of you mean nothing if you do not know how to manage a simple twin.
Use 80/20 fuel, and fit a glow carb on her. The methanol probably has hardened the membranes inside the carby, so it will never run well.
Even with a membrane set, the walbro is not the best choice.
