    Cub Carb Leaks

    I finally managed to assemble my Cub carb with the new kit and adjusted the float height and drop. Now when I blow into the inlet tube with the needle on its seat, I get no flow as I would expect. When I invert the carb the needle drops off its seat and I can blow through it ok. When I...

    Grandpalove reply did not come through. I wish he would send the photo again so I could save it.

    leaking carb Cub

    I put a cheap kit on my cub and still leaks Most of the leakage is at the tubing inlet likely due to bad threads. I put the top half and the whole carb less the gasket in a tub of water and all I see is big leakage at the tube inlet,nothing else. My little compressor only puts out about 5 psi...

    cub float adjustment

    what purpose does the adjustment for float drop serve? What difference does it matter if the float bottoms out? The float needle adjustment can easily supply any gas needed I would think. The main adjustment is to the needle shut off particularly during shut off. Also, is it necessary...

    Cub fuel line

    My cub gas line is a 5/16 tube that screws into the carb with a fitting that leaks and has a ferrule on it. Was the original like that with a ferrule? Or was it a 45 degree double flare or a single flare? I go a new kit for the carb and do not want to screw it up when I connect it up...

    Farmall Cub No compression on cyl #4

    Yes but not sure they are still in business. A big flood hit them hard many years ago.

    Farmall Cub No compression on cyl #4

    Hi....I am in Union, Mo. I am still working on the stuck valve. I cannot see the piston and very little of the valves with the plugs removed. I managed to get it running last week by cranking it with the hand crank very fast ( I have a mag and hand crank with no battery). I read somewhere...

    Farmall Cub No compression on cyl #4

    Is it possible to remove the valve cover plate with the manifold on? I would think getting access to the valves in order to spray them with lubricant would be a good thing to do. My exhaust pipe goes under and out the rear of the tractor. My big fear is that once I get the valve freed up...

    Farmall Cub No compression on cyl #4

    I can get to the sparkplug hold easily now that I have the hood off but not tried to move the piston and since it is #4 I would never be able to get to the plug hole with the hood on! I cannot see much of the valves through the plug hole. Would it be better to pull off the side valve...

    Farmall Cub No compression on cyl #4

    After sitting for a month or so this fall, I could not start with a hand crank and magneto. Ran fine at the end of summer and the engine always ran good after an overhaul a few years ago and with very few hours on it. I think the rings are good but there is no compression on cyl #4. I am sure...

    cub j4 magneto

    The mag fires twice per revolution so it must fire on both the power and exhaust stroke. I think it rotates clockwise looking into the engine drive. Hope mine works when I finally get it installed!

    cub j4 magneto

    Yes, you are no artist but I think I understand it. You are a great help! I learned here that the mag only produces voltage to the coil, points, and condenser when rotating. That seems obvious when you think about it! My problem now is adjusting the points. They slide in a...

    cub j4 magneto

    I cannot believe the trouble I am having setting the points. I have done this on other distributors all my life and I am 84 now but I should not have so much trouble. Maybe I have the stationary contact misassembled with the parts that hold it. I have the stationary point fit into the groove and...

    cub j4 magneto

    If I understand correctly, My new coil is ok and yes, the ohms are 9000 not 9. So right now, I have the coil mounted with wire connected to the points and condenser and also the kill terminal and everything shows grounded when the mag is not moving regardless of points opening or closing...

    cub j4 magneto

    I just bought a new coil for my cub j4 magneto. I have not installed it yet but question if the wire from the coil should show continuity to the high voltage nub on the coil. I measured 9 ohms resistance from coil wire to high volt nub. Should the coil wire be grounded when put in the...
