    2005 115 Johnson PLSOR dies at idle

    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!

    2005 115 Johnson PLSOR dies at idle

    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...

    2005 115 Johnson PLSOR fffffffffrustration... (still dies off idle)

    Fair enough, but I didn't mess with any adjustments. Alright, this may be weird, but when I pop off the float chamber, it feels dry, as if there was no gas in it. There is gas draining from the carb, though. Something to explore, or is my paranoia getting to me?

    What do you mean by that? What do I look for?

    2005 115 Johnson PLSOR fffffffffrustration... (still dies off idle)

    It smokes too much even for a two-stroke, backfires occasionally, and there is more raw fuel in exhaust than I am comfortable with - sounds like rich, right? Yet, open the throttle, it sputters and dies, as if it were not enough gas. Why I am getting both of those symptoms at the same time is...

    What is that? Thx.

    The pump seems functional, then. What else I might be overlooking?
