    This is what happens when you don't have any scheduled maintenance. The crew just run it until it dropped. I just found this in one of the trailers. This unit was last checked in 10/2009. At that time it had ports cleaned plug new shoes filters. Keep in mind this unit was over 5 years old in 2009. So it ran two more years.

    Yes all that gloupy stuff is oil/clutch debris all mixed together. I don't know
    how the oil got into the clutch area because the crank seal behind the flywheel was dry.

    And you can see that the shoes are down to bare metal.

    So the unit wouldn't start.....Put new crank seal behind recoil, had to put
    a replacement coil, put carb thru ultacleaner, new plug, and had to remove and clean oil out of the on/off switch it was shorting. The unit cranked up and runs fine. And new clutch shoes. I am planning to pull the head off to check condition of the piston rings and bearing.

    This may be my first unit that I couldn't get going. Replaced coil(warranty just under 10 years), new off/on switch it was full of oil, new seal on recoil side. The unit started a couple times and stopped. I pulled the head and cleaned all the transfer ports and muffler side port. They weren't bad. Put it back together nothing. Cleaned carb and put in kit. There is a hunk of the skirts on piston that got knocked off and was apparently ground up inside the engine. That may be my problem. I will put a used piston in to see.

    If you got seven years out of this machine forget the poor maintenance.
    My trimmers with top maintenance don't last more than two seasons:weightlifter:

    yeah, def who cares. dont put money into it, not worth it esp for that much use.

    we get about 4-5 years with little to no major maint. we occasionally replace clutches, but rarely.

    This unit is almost 10 years old......I am going to get it running one way or another and for less than $20, not counting labor. It helps me understand how to fix stuff quick on new machines.
    I put another piston on it since the one on the unit had a little chunck out of the skirt. As expected that changed nothing. I did verify my carb is working by putting it on another machine. I did a compression test and it was 90. I tested another 261T with about same age and it tested 90 and starts and runs fine.

    I guess I should bump this up to the stump the mechanic:laugh: I think I now know what the problem may be and I missed the biggest clue that is shown in those first pictures. Anybody have an idea?

    Hey Ed are you sure you still have good spark.Check the ground wire heck disconnect it off the coil and see if she lights off.Prob something simple good luck.

    Also wanted to give you props on all your echo threads and pics much appreciated. :waving:

    From the looks of things, you should have replaced the seal behind the flywheel. All that grit, you might wanna take a close look at the shaft/ seal
    contact area.

    Do you not have a vac./pressure tester?

    I thought sure that the seal behind the flywheel was out but it was clean
    and dry as could be. There was a little leakage on the other end of the crank behind the recoil but no gue like in the picture. I put a new seal behind the recoil. Yes I got a pressure tester rig that will be used next. So both crank seals are good and I verified that the cyclinder gasket was good when I pulled the cyclinder off twice.

    Do I see a pinched/possibly broken ign wire?

    As long as that wire is not grounding out, even if you take it off from the coil, if the coil is good, it wouldn't stop it from giving spark.

    One wire comes from the tab on the coil to the switch, the second wire come from the switch to a ground on the coil. When you turn the switch off, it grounds the coil.

    I have had a wire (the one coming from the coil) where the covering was worn, and rubbed against the housing causing the coil to ground out.
