D) Rotate the flywheel, check if there is spark, the cylinder is in normal compression state, you can start,
4. How to adjust the ignition timing?
A). Check that the piston connecting rod is at the leftmost horizontal position (as shown in Figure 1)
B). Check the closing condition of the ignition switch and brass (Figure 2)

Is there any way that you can slow the engine down so it will idle? I did not see any throttle control on there I understand about the air mixture believe me.I await your reply. That I have stated before I am very interested in buying it I just have a few questions. Loyd
I don’t think it is a throttle control. It is more likely that it is a mixture control. The fuel/air mix needs to be right for it to run properly.
Tell me why a throttle control on both those is there not hit and miss engines from what you were showing in your little diagram movie there is no throttle on them they constantly run at one high speed that’s not exactly true. Is it? I am still very interested in purchasing them but I’m still looking at I’d like to have them all but right at this particular time I can’t afford it if you know what I’m saying. Well take care my friend and May God bless each and every one of you. I patiently wait your reply. Loyd Kampf
