    jubilee hydraulics

    Sometime back, I rebuilt the square hydraulic pump on my father-in-laws Jubilee. I used it the other day & noticed a problem. When lifted to the top with a bushhog on it, it would drop a little bit & then come back up, drop again, & repeat this consistently. What is up with it? Thanks in advance!

    Chevy valve springs in a Z

    I know they will fit, but do they have to much tension for the Z engine? Will the rockers flex/bend? I also wonder about premature cam shaft wear? Thanks!

    Z oil cap

    Anyone know where I can get the small oil cap for my ZTU? Also, I saw a cap for a Farmall 140 in an add that also looked like it. Will it work? Thanks!

    Sachs Dolmar 114

    I need some help with my ignition on my 114. Mine just died one day. Is it the coil or the pick-up that fails? How can I test it? I read somewhere that a PS6000, PS6800, 116si, or 120si coil will work. Any help on getting me going again would be greatly appreciated. Thanks!

    Sachs Dolmar 114

    I have no fire from the coil. No short to frame. Does the coil go bad or does the pick-up under the flywheel fail? I have been told this is a discontinued item from factory. Is there an aftermarket available? Thanks in advance!

    Sick Stihl 029wb

    This saw starts well when cold. When it gets warm to hot it starts loosing power & shuts down. Fuel is not a problem. The spark, however, is another issue. If I crank it easy, it will not fire the plug. If I pull hard & spin the motor really fast, it will fire a blue steady arc. I have changed...

    Internal mag timing on K4B

    I took 3 mags a part to build one. Everything is good, I have fire, but I'm not sure about the internal timing. With the cam high sides up & down, I put the "c" mark on the fiber gear up on the right side of the bearing plate, just across from the plate retaining screw. I guess there is what I...

    I have a crank out of an RE185 that has had the rod journals turned .030" in the past. Where can I find bearings? I can find 010" & 020", but no .030".

    Timing a Z

    I read in a post some back that if you advance the timing one tooth on the cam it will give it more power. Am I recalling this correctly? If so, will doing this on a mag engine help or just make the hand crank a flying weapon? Thanks!

    rod bearings

    One more question: I have a crank that was turned .030" at some point in time. I want to replace the bearings that are in it. Are there any aftermarket numbers for this? I can't recall running across a set from MM. Thanks again!
