Is my soft start working properly?

Usually the engine seems to idle at a lower speed for about five seconds after the start, then it pops up to normal rpms.  This is quite noticeable when the soft start is operating.

Good to know, I will look carefully for the lower RPM, I can't say I have noticed that though.

About the abrupt starting, is that normal? I would expect it to come alive more like an automobile.

I'm not sure I understand what you mean by abrupt.  It seems to me that most engines catch and start running quite suddenly.

.... "catch and run suddenly" , then maybe there is no concern. I will look for the RPM bump tomorrow.

I would paint a white mark on the flywheel and use a timing light to see if the timing is retarded correctly during start.
