John Deere 50v
« on: October 12, 2003, 07:26:54 PM »
My neighbor gave me a John Deere 50v that he had laying around in his garage. They are moving and he hasnt used in in a long time so he brought it over and gave it to me. He told me that the fuel line was " bad". So I took this thing apart and found that the fuel line that ran from the tank to the crab was actually broken. I replaced the line and cleaned everything up. Its in REAL nice shape EXCEPT I can get it to run. If I supply fuel to the crb using a seringe directly onto the carb it runs GREAT. Trouble is I cant get fuel from the tank to the crab. Ive primed the line checked everything I can think of but still not running. Do any of you have any idea or suggestions on how I can get this perfectly good saw to be a running perfectly good saw?

If the tank vent is open, the fuel is free to flow  through the filter through the line and isn't being pumped into the carb it is probably in need of a cleaning and a rebuild with a carb kit.

If the 50v is like the 90v, follow the fuel line to where it enters the fuel tank. you will see a small clip and a single machine screw. Remove these and you will be able to withdraw the fuel line and fuel filter from the tank. If the fuel line was broken outside the tank it may also be broken or cracked inside also.

As Chet said, It is probably the fuel line in the tank or the filter in the tank.
FYI, that saw is actually an Echo with green clothes on. ;)

Tyhanks fellers.....well the line IN the tank is fine and from the tank to the crab is fine...so I guess it has to be either the filter in the tank or the rebuilding of the carb..or both...SDsaw...this particular John Deere 50v is actually yellow....I knew it was the same as the Echo by the Kioritz Q500F....seems to be a GREAT saw....almost reminicent of an older Mac...thanks again for the replies...

Simply blow through the filter, and you will know right away if that is the problem.
Otherwise it's time to tear into the carb.

That would be the HU Tillotson carb.
There should be an idle screw in the top cover.
The fuel pump is near the top.
You take the top off and there's a gasket and the fuel pump diaphragm is just under that.
