    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.

    How do I check kill switch?

    You wouldn't have had spark if kill switch were a problem. Did it suddenly happen, or was it sitting a while? How's compression? Try spraying starting fluid down carb throats and giving it a crank.

    *Sigh* Yes.

    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. I'd go with aftermarket: https://maxrules.com/VRO_04-90.php

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

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

    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.

    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.

    It is a VRO, but oil injection was removed long ago; I am running pre-mix. I was thinking about getting an aftermarket non-VRO rig; what's the wisdom on that? Thanks!

    Iiiiiiiiiiinteresting... As I said earlier, if I pressurize the system with a primer bulb, no obvious leaks. If I then give just a tad of suction to the pulse hose connection at the pump, gas comes out - not a lot, 2-3 cc's at the most. Does it look like a leaky pump? Thanks!

    That's what I am wondering about, because it smokes too much even for a two-stroke (smoked A LOT more before carbs redone), lots of smoke on startup, and when you close the throttle, a big puff comes out. Pump checks out OK per manual, but there is always some gas in the pulse hose; that doesn't...

    Did it as a part of restoring factory settings - took them out and blew the screw hole (and the orifice) with carb cleaner.

    So I assumed wrong. Somebody did mess with idle screws: not only they were off, but all carbs were different. Returned to factory settings, major improvement. We'll see how it behaves on the water. Thanks!

    Yep, next step. Thanks!

    #9 in the picture above? Already done. Will tweak idle screws and update later.

    2005 115 Johnson PLSOR dies at idle

    Good point, didn't think of that. No, actually. There are 4 metering bodies with bowls/floats/valves/jets, and there are two throttle bodies (one per pair of cylinders) with butterflies; the idle needles screw into the throttle bodies. I've re-done the former. For throttle bodies, I just blew...

    >34 looks like idle needle It is. I am not messing with carb adjustments, though, before eliminating simple things (and for that, I'll probably take it to the shop, since I am still having nightmares from trying to balance 4-carb setups on my old Hondas/Yamahas). >bad pump Possible; I'll get...

    Alright, after sorting out earlier problems with the project (dying when throttling up - don't ask me how, it just started running OK after unscrewing and blowing out the jets for the nth time), here's another: dies at idle. Starts OK, idles for a few seconds at about 700-800 rpm, then sort of...
