A strange starting
 

Greeting all.

I have a little problem. It's bothers me lately.
The problem is: sometimes when I press start engine button without touching anything else engine hardly start. When it start all is ok.
When I do same thing but while pressing eng.start button, at the same time, just blip the throttle engine start like it should.
It started so I had a problem every tenth start but now I have problem every second start if I try to start it without blipping throttle.
Don't get me wrong now I have habit to blip the throttle when starting it and all is ok. But I don't like to rev engine when cold start. Sometimes it happens that instead of blipping throttle I rev it.

I have to note that all other things are ok. Fuel consumption is ok, engine doesn't smoke at all, everything just fine except starting without throttle.

What do you guys think. Is it misadjusted TPS? Spark plug (it looks ok)? Some broken hose (don't see any)?

Regards.

maybe yer Battery is on its way out,,, that happened to me a while back

Idle speed OK??? Should be 1500 RPM when hot I believe.....
