    Water temp or head temp?

    So I got that dual-temp gauge from a company I won't provide with a free advertizement. Put the sensors into water pressure ports. Works acceptably well showing cooling water temps. Apparently, the motor (j115plsor) has a blind hole in each head that also looks like 1/8 NPT. I wonder if that's...

    2005 J115PLSOR weird oil leak

    Probably not, the block is clean all the way down. The seal and driveshaft are right there, and there seems to be just enough of an opening for the spinning shaft to sling gunk around.

    I'd rather have it come off than have the crank seal blown.

    It IS, if it (partially) fills with liquid.

    2005 J115PLSOR weird oil leak

    Fair enough, I was keeping it under 3K per break-in instructions. I do suspect I have excessive crankcase pressure issues, because recirc hose kept popping off

    2005 J115PLSOR intake overpressure/raw gas?

    By way of an update, replaced reeds with Boyesens (and also replaced primer gasket). That cured most of the problems described here. Smoke is down to acceptable levels.

    2005 J115PLSOR weird oil leak

    It does feel like half-evaporated 2-stroke mix. Except that it almost looks like it's coming out of the bottom of the crank - everything above the exhaust housing spacer is nice and dry. Combined with the fact that I see more oil/fuel in exhaust than I am comfortable with, I wonder if fuel pools...

    2005 J115PLSOR weird oil leak

    It's just that, one, there is nowhere for the stuff to come from but the crankcase (and if it does, why it is pooling in there?), and two, I can't see where it's coming from - between the powerhead and midsection?

    2005 J115PLSOR weird oil leak

    Where is that stuff possibly coming from? Fuel system is tight all the way up to carbs, floats set right (I think - manual calls for 1 1/16...1 1/8in or 17... 28 mm (sic) drop). Does not look like fresh fuel anyway; more like 2-stroke like mix that's been sitting for a while. Thoughts? Thank y'all!

    2005 J115PLSOR intake overpressure/raw gas?

    Stupid saga continues. Looks like someone has been messing with reeds, because one of the shims is missing. I wonder if they have already been flipped, because the tip seems to lie flat against the reed block, but the mid-section shows a gap.

    2005 J115PLSOR intake overpressure/raw gas?

    I am at the end of my rope, because this is the only thing in intake I did not mess with (OK, primer, but that should not blow the connector lines off) - and I am pretty confident in the carbs.

    2005 J115PLSOR intake overpressure/raw gas?

    Pulled the reed blocks. Reeds look OK (no obvious wear), but if I shine a light down intake, there are visible gaps - not very consistent petal to petal. Thoughts? Thanks!

    2005 J115PLSOR intake overpressure/raw gas?

    So I was misinformed on that; fuel IS supposed to flow aft (so that bearings stay lubed even if one of the carbs runs lean, I imagine?), and check valves are operational. But what could possibly cause overpressure that blew the lines off?

    2005 J115PLSOR intake overpressure/raw gas?

    You might be right. Gentle suction on priming line (solenoid not energized) gave me a squirt of gas, but only on one cylinder bank. How do I properly check for that?

    Too much even for 2-stroke, IMO

    2005 J115PLSOR intake overpressure/raw gas?

    I hope it does. Just ordered one. Surprisingly cheap, but a pain to find. No, but after a minute it sort of gets to what I expect to be normal for a 2-stroke.

    2005 J115PLSOR intake overpressure/raw gas?

    Is there a useful diagram of those connections out there? Solis manual is not too much help. Too much even for a 2-stroke, IMO. I can shoot a picture, I imagine.

    1. Pulse 2. Not likely. Old VRO was leaking into pulse hose (I think I grumbled about it on this forum), but replacement is only 2 years old, I believe. Did not solve smoke problem (separate, but probably related issue) much, either.

    2005 J115PLSOR intake overpressure/raw gas?

    Correct. This is a frame from a video with engine running. The line is the same line shown in the first pic, only the other side, and it was blown off its fitting. Based on what I am hearing at the local shop, it is supposed to recirculate excess gas from the crankcase back to intake. So, if...

    2005 J115PLSOR intake overpressure/raw gas?

    Except that I am talking about pressure NOT in crankcase, but in the intake tract between throttle plate and reeds. Which should be atmospheric or less, because of the sucking action of the case. And if it is ABOVE atmospheric, as stuff spitting out of the tube suggests, where, in your opinion...
