Hi all,
I remember reading some years ago you could get a little hand-held pump that you could set to either vacuum or add pressure. Someone used one in these forums I think for testing carbs, you could set it to vacuum and apply negative pressure to see if a needle was seating correctly, or apply pressure, but I can't remember what it was called or where to get them. I did find it though some years ago. The only thing I can see is a vacuum pump (for brake bleeding) as seen
here, which iirc looked similar to this design but it seems this one only does vacuum.
[EDIT] Just came across
this one though $140 is a bit steep. Anyone know of a cheaper option?
