Hard Starting Hot

[Rich72C10]

Carb is on its way back!

Man, getting information from these guys is like pulling teeth - I really don’t get that. Even if everything is perfect, I won’t recommend them because of that.

So after 3 requests for information (after I got a email it had shipped back) this is what I got.

Internal adjustments made to help you with the tune

I was like WTF?!?!? Then after more or less begging for additional details I finally got today:

Hi, We went to 72 jets with 36B primary rods. We restricted the bypass air, so idle can be lowered. We checked and adjusted throttle linkages to verify the secondaries won’t open any at idle to let air through. We removed the clip on the needle/seat to let it set when fuel is not flowing to prevent back flow. This should provide easier start up. The vacuum brake was replaced. It had a slight leak and is probably the source of the whistle.
Thank you.

I remember that Mark had a pretty good name with Q-Jets. Hopefully it runs well when you get it back, and was a one-off with the problems.

The implied relationship between empty fuel lines and hard starting is odd. You're using fuel in the bowl for starting.
