Due to the weather situation I did not have a chance to see how new engine is going.
I seem to think that these type of engines, like my sportster, don't like fooling around with starting repeatedly and not going anywhere.
Next day I found that neutral switch light did not come on again, I unplugged little cable from neutral switch and cleaned it a bit with brake cleaner, I found also that plug is kind of loose fitting and could not think so quickly what to do about it other then solder a wire on but after the cleaning it stayed working.
Having the engine running in the garage I found that it was not very stable on the rpm's.
I am going to put some pictures on later, thanks for Oil tip
I do have a question though, are those valve lash adjusters not sensitive for thick oil?
