Question about John Deere 3010,3020 Tractor Basic Carburetor Repair

Open Question

I have a John Deere LX173 which is 12 years old. It will start fine and run for about 5 minutes when it start to backfire then stops. If I let it set for a few minutes it will usually restart and run fine until I'm done mowing. I have replaced the fuel pump and filter. I'm thinking it is a carb problem, maybe a choke problem.

Sounds like you may have a problem with Choke adjustment, or perhaps a broken choke cable. Do you have a workshop manual?

Looked up detailed isometric diagram w/ parts denoted on John Deere website. FixYa website was a litele misleading. I did not realize that accessing a question posted "for free" would cost me something to get the answer. It's kind of like askin a neighbor as a neighbor to give you a hand and then he sends a bill.
Thanks but no thanks

SOURCE: John Deere Gx75, kawasaki 9hp motor- oil in carb!

A very common problem with the GX series with Kawasaki engines. The carburetor 'inlet needle' sticks open and fills the crankcase with fuel. When checking the oil, it can be difficult to see the gasoline and the level appears to be OK. Remove the dipstick and smell the oil, you may detect a gasoline smell. Also, drain the oil, and you may find much more fluid than you expect.
The solution on newer mowers was to install an 'in-line' shut-off valve to keep the fuel from syphoning into the carburetor. The inlet needle and seat in the carburetor is NOT replaceable, so a new carburetor is the ultimate solution, but VERY expensive. Installing and using an in-line shut-off valve is more affordable.
Also, this situation is common when machine is transported on a trailer, as the bouncing causes the needle/seat to leak. When transporting, always turn off the fuel supply to the carburetor.

for openers i would start by having someone check the valve clearances. sounds like you are out of time, and that is a common issue with a mower over 3 years old. if the intakes are opening way to late, and not far enough, you have a problem.

I have a John Deere 2E leaf blower. Lately it has been hard to start but runs fine once it is up and running. Would it help to adjust the H or L screws on the carb?


The H (High Speed) and L (low Speed) should not typically need adjustment. What happens is the diaphragms get stiff and do not operate efficiently. If the unit is over 5 years old and/or the fuel is not completely drained with the unit run dry at the end of the fall, then I would suggest replacing the diaphragms within the carburetor. This along with spark plug change, air filter cleaning and a check of the muffler to insure it is not clogged is considered a basic tune-up.

Hi,
Sounds like the float is bad - what happens is the float sits just a little off and when you add the demand of more fuel it skewers the RPM by starving the engine.
Try removing the carburator and either adjusting the float by bending the tab or replace it. As part of this repair i suggest you just replace the needle and seat as well if they are over a year old.

Thanks,
Gary @ Fix Ya

You may try blowing backwards from behind the fuel filter into the gas line. Not to much air pressure though. Make sure the gas cap is off.
