QD 21 low speed jet screw

[Rick-va3rzs]

Quick question

with our rebuilding the carb can anything be dont to stop the low speed jet ( screw) from unscrew'n ?

I was out on the water today and just noticed that the low speed screw was allmost all the way out I say I had to screw it back in about 10-12 times and reset it

this only seems to happen when I am near WOT

I was running away from a storm that came up quickly on us .. I would have hated to lose the screw before I got the boat on the trailer

Thanks for any and all help

tighten the packing nut that the needle valve passes through. Try not to make it to tight though. Just snug it up so it offers some resistance to the needle valve shaft.
