Q-Jet accelerator pump roll-pin
« on: October 10, 2020, 02:10:07 PM »
( searched for "accelerator pump lever" and "roll pin" and got no hits.)

Played with a '77 Chevy 350 pickup Q-Jet yesterday.  My friend "rebuilt" it.  That is, he fumble-fingered the thing til I couldn't stand it any more, then I put it back together with new gaskets.

Something I don't remember from other Q-Jets:  The accelerator pump lever pivots on a tiny little roll-pin.  The airhorn casting did not have a hole drilled all the way through for the pin to fit into.  I usually just smack the pin with a thin punch, push it through towards the choke tower to free the pump lever, and therefore the linkage down to the throttle body.

Since this casting didn't have a through-hole, we had to leave the lever in place.  Made things more difficult.

HOW would you ever get that roll-pin out? I don't like the idea of drilling a steel roll pin shoved into a soft-metal casting.

Leave the lever in place and install one of these.  Just cut the old one and remove it.......Cliff
