Honda mower choke setting

I'm hoping someone might have a bit of knowlegde about Honda carbs on garden machinery. My mower is a PITA to start and I think it's because the choke doesn't come on fully. The picture show the choke valve as fully closed as it will go! I'm at a loss as to what to adjust as everything seems inter-related and TBH I don't see what can have changed since I bought it some years ago. No amount of adjusting the throttle cable will permit the choke lever to move further than it currently does as arm 3 seems to restrict it.

In the picture, arrow 2 points to the lever that actuates the choke. However, it is limited or hindered by the arm at arrow 3. I have no idea what screw 1 is for. Does anyone know how to set these things up? It's a GCV160 and the manuals I have don't even show screw 1 let alone say what it's for.

Hmm, interesting. Does the mower actually start, or just slow to start?

Honda mowers are usually bullet proof. The need an oil change every other season, lube friction points and clean the air filter and check the spark plug gap each year. Even the drive belt is good for 10+ years!

I had problems with mine getting it to start last year and eventually traced the problem to a faulty ignition coil. Local Honda dealer wanted 40+ (half hour) just to look at it. I didn't buy the genuine part given it was fairly expensive. Think I possibly sourced it online.

Yep, it starts, it just takes a number of pulls esp on colder days. It also runs absolutely fine once started. I'm pretty sure it is a choke problem but short of fitting a longer rod to actuate it I can't see how to adjust the standard setting.
