I am getting my first 80cc two stroke in the mail today. I am sure to have many problems and questions as this is my first large two stroke engine with a spark plug instead of a glow plug. I will be breaking the engine in in below freezing temperatures. I am concerned of seizing the engine. I will keep it inside before start up. But will have to shut it down for the main roads as it is illegal to run them on the road here in ny. I will also be experimenting with exhaust muffler packing. I picked up 0000 steel wool which is flammable. I am going to wrap steel netting around a broom stick them wrapping that in the steel wool. Setting the steel wool on fire beforebefore packing it in the muffler to dampen the sound. I will post to let you know how it turns out. I will ruin it before and after to hear the difference.
