This is about my 2009 LX150. I have noticed that it starts just fine without any throttle input on a cold winter day but on a hot summer day it needs considerable throttle input to fire up and before it can sustain idle.
This happens only after it has been unoperational for few hours (overnight).

I am just curious why does it do that ? What does ambient temperature have to do with how the first start of the day goes ?
Is this normal for this engine or is there some issue in fuel delivery or carbuerator ?

It's a fuel delivery issue.

And how many miles ago were the valves adjusted?

About 2978 miles ago (that's the number of miles on the odo)

It would not hurt to check them, then.

Likely the air fuel mixture screw is not adjusted correctly.
