Johnson 1957 7.5 hp High & Low needle valves

[riverrat 2]

Does anyone out there know how many packing washers should go in the high and low needle valves? Mine were sucking air so bad . All I could find was a few little pieces. I know they come in a pkg of 4. does that mean 2 for each valve or 4 for each valve.Would appreciate your help. I am going to replace the impeller with a kit that arrived yesterday but when she fired up the one in there worked so I thought I could put it un the back burner and start on the stay running problem til I saw water coming out where it shouldn't. Thanks for all the help so far guys.

I think if you look at the parts breakdown it will show 2 packings on each needle. I put at least 2 on the needles, sometimes I use 3 if they will fit just to make sure I get a good seal.
