    520H Onan dies when warm

    I ordered a new fuel pump. Can an upper cylinder soak be performed on the Onan motor?

    What Size Lathe to Buy? What do You have?

    A couple years ago a good condition Southbend 24-inch lathe sold locally for $1,500. It was a factory modified 16-inch swing with 8-inch riser blocks. The bed length wasn't huge so that it would have been ideal for me, but I was #2 in line and it was heavy to move without help. The seller sold it cheap because he had to be out of the space by the weekend. If you haven't done so, register with a service that provides alerts from Craigslist and always be ready to pick up the lathe - have trailer, hoists and rigging so you can move on it. You probably won't regret overspending somewhat on a good lathe - not that I take my own advice ! I'm cheap. Tim

    520H Onan dies when warm

    I left it idling in a flat spot and it didn't stop running. When I attempted to back up a 30 degree slope it does. I left is roll down the hill and it started right up. It idled for 10 minutes with no stalling. Could there be a fuel issue with slopes?

    Speedex 1631

    I just drove the 520H with a loaded trailed down the hill on my property. No problem hauling about 400 lbs but it was unable to pull the empty trailer up the 30 degree hill. I can drive an automobile up that 75 foot slope. The 520H need better traction. It is not weighted. The Speedex looks good and I hear that most parts can be repaired or fabricated

    520H Onan dies when warm

    The hour meter says 1730. The Onan will fire right up. But it loses power after a few minutes. I ordered a head gasket set and will decarbonize and inspect the cylinder head. First, I'll check the compression. I was planning on rebuilding it, but the motor might already have been rebuilt.

    520H Onan dies when warm

    I have a 4WD Kubota for pulling. The Speedex is interesting looking but I wanted a use for it. Nobody seems to want garden tractors unless they come with attachments like blades or tillers. I read that the Speedex attachments are difficult to install, but I won't have any extras. I have a Ford LGT 125 (Jake), the 520H, C160, C120, Power King 1614, Cub Cadet 782, 3 Sears Suburbans and the Kubota B6100. The Kubota is much better than any of those for actual work and it only weighs 1,050 pounds. The 4WD makes all the difference.

    520H Onan dies when warm

    It began to stall a few minutes ago. I adjusted the choke and it smoothed out but could not get any power - no RPMs. There must be a carb issue. Are new carbs available? Where is the best place to get a carb kit ?

    Speedex 1631

    This one has 3 point hitch but no hydraulics. It is said to run but not run very well - carburetor issues. I have a Power King 1614. Does it compare to the PK ? My PK doesn't have a 3PH. They both have the T-92? I only use these for pulling trailers and moving things. Do you think its better than a 520H at pulling? My 520H has plenty of power but traction isn't so good, I installed tire chains and that helps but its not heavy enough.

    Speedex 1631

    I have come across a Speedex 1631 with 16 hp Briggs and Stratton motor. What are the strengths and weaknesses of this model ? As the Power King, it has the T-92 transmission but seems to be belt drive. Tim

    What Size Lathe to Buy? What do You have?

    Did you find a lathe? I don't see many good deals in the Austin area. The machine tools that seem good are often sold within hours. A trip to Dallas or Houston is probably worth the effort. Any working lathe is better than none at all. I got a Southbend 9-inch benchtop lathe for $600. It was dirty but not in bad shape. Lots of projects can be done with a 9 x 20 Asian lathe. Make a habit of checking the local scrap yards as machines which don't sell at auction can end up there. I saw a Southbend Turnado at the scrap yard that looked to be in good shape, but I didn't have room for it as the bed was pretty long and it had 5 HP 3 phase motor. Tim

    520H Onan dies when warm

    520H runs smooth for a few minutes then dies like switch was cut off. Starts again and will run for a minute or two then dies again. The previous owner said he replaced an ignition module last summer, for this reason. Apparently that wasn't the cause of the stalling. Are there electrical diagnosis procedures for this engine?

    P220 Onan

    some have installed a water mist system on air cooled motors that is directed at the cooling fan, not at the fins on the cylinder. The water evaporates and cools the air. This system also helps an oil cooler to be more efficient. http://forums.pelicanparts.com/porsche-911-technical-forum/150982-water-vapor-cooled-911-rubbermaid-solution.html

    520H with 1750 hours

    Is it easy to access the spark plugs to do a compression test on the Onan? There can't be a loose exhaust valve when the compression is normal. I have a compression tester. Are the spark plug threads the same as an automobile ?
