HP Carb "Auto" Choke

[JoshCiares]

I have a brand new HP Carb that won't come out of choke when I go throttle or even manually pull the cable up. I've never gotten this thing to work properly but I'm quite certain I put it together right but obviously not? If I push the pin where the air filter is, I can get the lever off of the choke disengaging it. Just not with the cable.

The HP carb is known to be a fancy paper weight, and not actually usable for motorized bikes.

I deal with a lot of SHA carbs as they are on 99% of mopeds here. It is very easy to screw up and install the choke lever in the wrong position. A lot of people also dont install the throttle cable the correct way so it binds or doesnt open all the way (another reason to why the choke wont open).

I had good luck running a clone SHA on my MB. The jet i needed was really small (i think in the mid 50s).
