    2086 Super Garden Tractor Coolant Loss

    Month ago I changed the coolant, installed new thermostat and radiator cap. After 2 mowings, the overflow tank becomes empty (1 cup). I have refilled twice. There is no obvious external leak, I pressure tested the cooling system to 12 psi and it held it, cylinder compression test was 180...

    2086 Super Garden Tractor Carburetor Issue?

    The advice from my original post was to look for corroded eletrical connections from the igniter and gasket concerns. I have since changed the igniter and the connection appeared good. Many gaskets were replaced only 250 hours ago when the camshaft was replaced. The item I have not...

    2086 Super Garden Tractor Carburetor Issue?

    Tractor is a 1997 with 650 hours. It has the FD620 Kawasaki, a twin 20 HP liquid cool. Over the years it has always run rough in hot weather, but always starts right up when engine is cold. Never a problem with winter snowblowing. Here is a copy of a thread I made a few years ago...

    20 HP Kawasaki Runs Rough 2086 Super Garden

    A discovery was made! As I was going thru all the connections (opened & all appeared OK), I came across a single wire from the igniter that had a spot worned down to bare copper. Repaired that wire, mowed today and the tractor ran fine in all RPM ranges! Yes, the igniter is easy to get at, so...

    20 HP Kawasaki Runs Rough 2086 Super Garden

    There is a Deere dealership within 1/4 mile of the closed Cub dealership. I may visit/explain my situation after trying the connector cleaning first, then do a 1-1/2 acre mowing.

    20 HP Kawasaki Runs Rough 2086 Super Garden

    Are the terminals that need to be cleaned withing the flywheel shroud? Or will they be accessible by just removing the side engine covers? Plan on looking at tractor either Thursday night, or starting Friday morning. I have looked at a service manual showing the location of the igniter and...

    20 HP Kawasaki Runs Rough 2086 Super Garden

    I will look into the wire harness connections. There are no mice nests present. Carb does have a float.

    20 HP Kawasaki Runs Rough 2086 Super Garden

    1997 model with 600 hrs used on a Cub 2086 Super Garden tractor, liquid cooled twin FD620 engine model. I have owned for about 5 years. Always runs great when first started, but last summer, it would tend to run rough after mowing for 1 hour. I only noticed this after turning the deck off and...

    20 HP Kawasaki Runs Rough When Warmed Up

    Here is the latest. I have done nothing to the engine except the following. I just remembered that about a month before my problem started, I had filled the gas tank up too much. About a day or two later I had gas seeping out of the cap onto the floor (sun shining onto tank). When I first seen...

    20 HP Kawasaki Runs Rough When Warmed Up

    I see someone else is also experiencing a wet air filter. Mine always has a coating of oil in it, but I never have to add any! Yes, there is a cooling fan. I will look to see if it is moving when the engine is running. I usually clean out the metal screen in front of the radiator, and there...

    20 HP Kawasaki Runs Rough When Warmed Up

    This is the FD620D, liquid cool used in a 2086 Cub Cadet Super Garden Tractor. Recently, it will run rough only after I am done with 1 hour of mowing. It appears as soon as I turn the PTO off, as I am preparing to park the lawnmower back into the barn. It starts right up when cold, but when the...

    2086 Starter Problem

    Brian, I have discovered my multi-year intermittant problem! As I was looking closer at the green wire that goes to the PTO (it was chafed, so there was my intermittant PTO off problem), I proceeded to unwrap all the black tape (about 18") that held the green ground wires for the PTO, starter...

    2086 Starter Problem

    Brian, if I was to install a relay, would the existing wire that goes to the solenoid, now run to the relay? Then a larger wire from the relay is attached to the solenoid from the relay? Where is the power coming from that supplies the relay?

    2086 Starter Problem

    Brian, if I should see a drop in voltage like you did, should I install a larger wire, or look at replacing the starter again?
