I am real big on engines, and working on them, so i wanted a small engine to just have to tinker with, and to fire up sometimes. im not too interested in actualy building a plane for now becuase i sink to much money into motorcross and my car. but i wanted a small engine cuz i love engines. i have a few questions about the engine i purchased on ebay.
-It appears ill need some sort of battery pack to start it, what do i need to get it going?
-what brand engine is it, so i can figure out the premix ratio
-i will probably run my sunoco GT unleaded plus race fuel in it.will that harm anything?
-what kind of adjustments are there on the carb? does it use a fuel/air screw or jets or what?
-basically this is just sorta going to be a model that i want to start up everynow and then, and id like to know the basics so i dont end up blowing it up, and id like to know the make so i could rebuild it just for fun sometime.
-one more question--i have a mazda rx-7 and am interested in rotaries, does anyone make a RC sized rotary engine?
thanx in advance.
