    Per the drawing, in the "specification chart" portion of the ACS page, all of these larger than 1/4" diameter are bored.

    All my parts showed up the other day and im questioning the rod ends yet. they are the part number GMM-4M-675 https://www.aircraftspruce.com/catalog/appages/aurorabearings.php they look plenty heavy but the threaded portion is not solid on the inside. Ill take a picture later on to show you all. I figures for 20 bucks a piece they should work.

    Ha I snoop around over there every once and a while but I don't dare post much anymore, Its hard to take advice from builders that spend more on there panel than I will have in my whole plane.

    Ditto. My napa sourced switch is my master switch, off-on only in the Mangy with a separate start button, yellow has off-on-start. 
    ~$12 at napa for either.

    Here's the Mike Stratman article on aligning the marks on the oil pump arm and pump housing for proper oil injection ratio. http://www.cps-parts.com/cps/pdf/Part45.pdf 
    A bump felt in the pedals every couple seconds sounds like the mid range is too rich.  To lean it raise the clips on the needles one notch.
    It is recommended to run premix in the first tank of gas after an overhaul.  That gives any air in the injection time to work out and you also can check the oil ratio the injection pump is using.
    For what its worth.  I pull the power all the way back to idle when abeam the numbers on down wind and leave it there for the rest of the landing approach.  Usually have to use a lot of forward slip on final if I want to touch down on the numbers.

    Rick is only against injection because it can't do 40:1 like he wants. There are thousands of Rotaxs out there running 50:1 and thousands upon thousands more non flying machines running it. You are correct saying that there is a point where there is so much oil going thru the jets of the carb the mixture effectively becomes leaner. I am not familiar with the crank balancer. Rick is pretty receptive if you come at him with the right angle. Have you tried talking to him?

    "the read I'm getting from the 2-stroke collective is there shouldn't be any vibration at all felt." Not quite. At idle a two stroke (at least 503,582) will rattle and shake like a pissed off snake! my experience above about 3K it should smooth out and you should not really notice vibration (from the engine) between 3-6.5K rpm . When you cut the throttle back to 5200 does it drop from cruise all the way down to 5200 and then you feel the bumps? or is there a gradual decline in rpm and as you are trying to reach 5200 you feel a bump? I am thinking if you drop your rpms all the way down to 5200 and then you feel a bump it would be more gb (poss the unloading of the prop allowing some slack in the gb), if you are gradually dropping it to 5200 and you feel a bump on the way down to 5200 it would be more engine (poss carb) related. As for the added oil Rick is against the injection-period. My Rick 582 has about 30 hrs and is premix (he wanted me to run 40-1) I did that for the first 10+ and slowly started backing it off to 50-1. He is just overly concerned with getting lube throughout the engine. I have about 15 hrs now running 50-1 and have no issues (this is on a gyro). My suggestion would be to get some time on it and go back to injection only- as long as you feel it is oiling like it should.

    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.

    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.
