Thermoquad help questions

Hi All,

I have rebuilt the TQ and using a Mr. Gasket spacer to my LD340 for now. I did a bunch of work this morning to the spacer, gasket, and some on the intake opening to get nice smooth accurate alignment. Should help some.

But I have a couple of questions:

1) If I am not using a choke on my 340 for now, do I need the choke pull-off? I know they serve more than one purpose, but is that only if using a choke? (I have a new pull-off, but haven't found info as to whether I need it.)

2) My TQ is a '73 440 unit, and this model has what I assume to be a bowl vent pipe off the off the passenger side top plate. What do I do with this? Plug it? Route it somewhere?

Appreciate any help, thanks!
