Topic: Press In Jets: How much "Press" before they are "in"??!

[liPPy]

I've just cleaned my carbs (1978k, PD42B) including removing & cleaning the press in slow jets.

How far do the press in jets have to be pressed before they are fully seated?

As it stands, there is a small gap between the shoulder of the jet and the top of the carb housing (see pic below). This is despite some considerable pressing force.

Do I need to close that gap? If so how? Lightly tap with a hammer? I don't want to overdo it...

Put a dab of some kind of lube like oil or Vaseline on the o-ring, and then push down while twisting till it's fully seated (no gap).  At least that's how I do other press-in type jets; I don't have experience with those carbs...

No o-rings here.. I just fold a rag on top of it and LIGHTLY tap it in, using an upside-down bolt and a ball-peen hammer. Good luck. There should be no gap.

I usually tap with the plastic handle of a screwdriver. Just light taps and it goes in.

Thanks guys! A short length of hardwood dowel, a couple of gentle taps with the ball peen and all was good.
