Understanding the “choke” system
Not sure on how to word this so hope I can explain it adequately! It’s probably simple but I’ve confused myself.
I understand that on first start of the day, it’s full choke with closed throttle. If the throttle is too open it can override the choke system.
As the throttle lever hits the idle stops which are adjusted for idle rpm, at what idle rpm would a ULS be at risk of having the throttle ‘too open’ for the choke to activate?
From reading, I also noticed that the choke had one of the holes enlarged in 2004 (my engine is 2002). Was this to help with starts? And is it worth doing the same on my engine?
Hope that makes sense and thanks for any help understanding the choke system. I did have a search but struggled to find the relevant topic.
