    Ruling out carb slides.  Both work and sync smoothly.

    Hey Guys - all very good feedback, much obliged.
    This is a fresh RR rebuild.  It's a '92 gray head w/"small" crank.  C-box 3 to 1 (I think - books are at the hanger to verify).   About 325 TT, 5 since the RR rebuild
    Joey -  I hear 'ya about adding oil.  Seems crazy to me.  It's got to be getting tons of oil becuz I'm watching the reservoir deplete itself at a good rate -- doesn't take long for a mess on the belly and r/h gear leg either.  Actually, more oil will lean the fuel/air mixture; yes?  I need to do a plug read ASAP.  The thing to do is a measured qty of oil and fuel levels -- do some equations and figure out my actual ratio.  I'm inclined to stop adding oil to the gas, I think the injector is doing it's job famously.
    One of the IVO blades has some minor tip damage that does concern me a bit.  Yes, I've verified the torques.  
    Another thing Rick did having added a balancer to the end of the crank - it's documented in the Eng log.  Something about the old cranks needing it.  Again, got to look at the engine logbook to verify but I wonder if this is a suspect.
    I'm left at a total loss but everytime I pull the throttle back I wonder if there's an imminent failure.
    So, the read I'm getting from the 2-stroke collective is there shouldn't be any vibration at all felt.

    That's how I am set up. Key just powers the bus on as a master and fires the starter solenoid. Once the engine is running you can take it out and toss it out the window. Take a look at Marine switches. $20 compared to $150 for aviation stuff.

    My Ivo runs 10x smoother than my Warp ever did. I would rule that out of the equation unless you are missing a chunk of blade or something. Has it been retorqued ever? Very easy to change the Gearbox oil and check the magnetic drain plug for anything that would lead you to believe there is an internal issue. Please post what gearbox you have and what ratio.
    The other thing that caught my eye was your mention of adding oil to your gas on top of the injector. I'm not sure why Rick has such a deal with running such a rich mixture. I did the math and if you are adding that amount of oil you are running close to a 32:1 mixture. Coming from a guy who ran 100:1 for 352 hrs and 5 years before an uneventful rebuild that makes me cringe. I don't think an overly rich engine would really describe what you are feeling though. I think it would manifest itself more as a miss. I've only ever heard of two gearbox issues before and both of them caused mysterious symptoms that drove their owners nuts before they figured it out.
    Please keep this thread updated. This is one of those type of issues that we need to see some closure to. Good luck finding a fix!

    Why not just rewire the mags so the mag kill wires only go to the toggle switches and not this keyed switch?  Then the keyed switch will only be a master (of sorts) and a starter switch.  Still need a key to start for security.   Jim Chuk

    Years ago Ford had a positive ground system - I remember in the 1970's Ford had several wiring systems burn up in the pickups - I have 3 Fords parked in my driveway - and I retired from Chrysler!

    Looking for ignition switch source
    I am looking to replace the ignition switch that came with my Kitfox III.  It is a 5 pin 3 position switch (OFF-ON-START).  Pins are 1 GND, 1 BATT, 1 SOL and 2 MAG.  Going to the OFF position will ground both mags at the same time.
    I do not want a switch switch has individual OFF positions for each mag (I do this with toggle switches separately).  I picked up a switch from LEAF, however it only has one MAG pin.
    Anyone know if these are still around anywhere?

    is this a new engine to the plane/you? or is this a new occurance to an old engine combination? It sounds more GB related to me, but I have no experience with the c box.  If it was a b I would say first thing check the  gear lube level and add some lucas oil stabilizer. It seemed to really tame noise in the gb on my gyro . Unless the bump you feel in the seat is from an rpm change in the engine, I don't think you would feel or hear the carb slide hitting the stops. If it was a warp drive prop I would say check the prop balance but again I have no experience on your prop

    I believe his point is that the material is rated at 125,000 lbs/sq inch, but to remember that is per square inch, and the point where the load is spread over the fewest square inches is where it will fail.  That would likely be at the threaded fastener if the load is carried by that fastener (as opposed to a fastener that just holds a part in position, but the load is not carried by the fastener - like the nut on the end of an axle).
    Sounds like an engineer, and you have to make allowances for them - they forget how to speak english after a period of time

    Row crops/grains don't have much if any subsidies anywhere these days.  And the amount of BS you have to deal with has increased, but it has for everybody else too! 
    Don't get me started on unions!  They had a purpose when they formed and did some good things.  Now they are primarily to support the union big shots, and to protect the worthless P.O.S.'s that should be fired.

    Here is a link to the Denso solenoid for less than half the price that Rotax wants but like Larry said:

    ACS sells one that will work for about $10  PN 11-03162.

    Kit planes article about internet picture posting
    Great article that could apply here from time to time and points out one of the main reasons I refuse to contribute to the other forum.

    Could be belleville washers on a B gearbox.  A C gearbox doesn't use them.
    If you have any friction in the carb slides, it could do this if they don't drop smoothly together.  I had to replace my original throttle cables because I was unable to get smooth action even after lubing them generously.

    Imo, there's nothing real rocket science about the solinoids.  NAPA should be able to help you find one that will work.

    It may be in need of servicing.  The belview washers relax after a while and no longer hold the lash tight.  This will definitely cause vibration.

    I started a thread some time ago on what I thought was a bad solenoid on my 912. It was a Denso brand, I'm sure a search on that word here would bring it up. No idea if you can use the same but I do have the old takeout which ended up being fine.

    IVO props are normally very, very smooth because they are light and the pitch design is equalized between the blades.
    How many hours on the gearbox?

    Odd to Me 2-Stroke Running Characteristics
    I wasn't sure which forum thread to put this in but since it all seems engine related here it is.
    So, what IS and what ISN'T normal vibration for a 582?
    I'm getting vibs between 3200  -- 5200 rpm. 
    At t/o power all is well and smooth -- engine runs right up to 6400 -- throttle her back to 5800 or 6 and climb out.  Rolling downwind pull her back to 5200 a disconcerting feel in my seat and sound "bump", nother second or 2 *bump*;  that I can feel and hear how I best can describe it.   Mixture? --  Lean or rich (because of improper fuel/oil ratio)?  I'm running the injector and Rotax Rick wants me to add an extra 3.2 ounces per 5 gals to ensure adequate main bearing lube as he puts it.
    Pull back to around 4k and let the nose down to base leg; now I'm getting a tingling in the foot pedals.   Rolling on to base, 3500 rpm and my feet are tingling and the plane is vibrating.
    Is this normal?
    The other factor is the IVO prop.  I hear they can be rough.  I'm thinking I've got 2 distinct problems going on. One ea with the prop and the engine.
    Today at warmup. I did take notice on the ground the vibration is definitely beginning at 3500.
    All you folks running IVO IFA please chime in.
    Thanks.

    They cut them (subsidies) to damn near nothing in 2014. That is for row crops/grain here in Louisiana. Now I debate whether to sign up or not because the hassle it is just about not worth it. But I have to submit and report in and deal with all the other BS like if I get too close with my tractor/disk to some "wet lands".
     
    BTW I have never been paid not to farm. That ended 25-30 years ago. And to get $800k of "your" money I would have to farm about 30,000 acres back then. But then surely my income would be well over a million dollars. BTW you make more than a million, you get no subsidies. 
    Why don't we talk about unions?
