2005 115 Johnson PLSOR dies at idle

[racerone]

If I had to replace a VRO pump on one of those for myself I would fit 2 pumps.-----Use some off say a 1966 model 100 HP.----Simple pumps with filter / sediment bowl.

There is a weird connection to vapor separator tank, so any pump simply won't fit. There is a couple of outfits that make the bracket to put on a non-VRO pump, though. Good news, the bracket plus pump runs about the same as VRO rebuild kit.

Just rebuild VRO pump and leave oil side bypassed

I myself would figure out a way to make the fuel system simple like they used to be !!!

Where do I buy bits for 5-point star with center pin security screws?

I'll probably mess with it later anyways. for education and out of curiosity.

#15 torx screwdriver I think.

You're right, it's Torx. They do have that five-point for idle adjustment, though.

Torx screwdriver sets are not a big $ item.

I know. I just can't seem to find five-pointed torx-like bits. I'm sure they exist.

Those are Torx. Six points solid. I am looking for 5 points (I believe Apple calls them "pentalobe") with a center pin.

Found them on Amazon, but they might not fit through adjustment hole.

It has "hex" right in the description, and I am pretty sure it means that those are SIX point security keys. And I already have those

 

[Harkonnen]

Fingers crossed, I got it. Installed aftermarket non-VRO pump; idles OK now, pulse hose dry, smoke is down to acceptable levels. Thanks y'all for your wisdom.
