Fuel Strainer on 430W

Stroby · Feb 6, 2018

I have a 1959 model 430W that occasionally just quits running. It's almost like you shut the switch off. I have a new JD ignition switch that I installed @ 6 months ago. After it sits for a while (20 min or so) it starts back up and may run for a while or may die again in a short time. Up to this point, it has always happened after running for @ 20 minutes or so. The last time it happened, I took the plug out of the bottom of the carburetor and fuel ran out....but only for @ 5 seconds. I removed the sediment bowl and the screen at the top, cleaned it, installed a new gasket at the bowl and it restarted. I haven't used it this winter (IL) but I keep wondering about it. I saw today where there is a fuel strainer at the elbow where the fuel line enters the carburetor. It's about the size of a pencil and @ 1.5 inches long per the photo. I called the JD dealer and they only want $60.48 for that little feller. Question: Do I really need that at all? Any other suggestions regarding what may make it do what it's doing? Thanks in advance.

I do not know that tractor as such but all the fuel strainers I have seen that are in the carbs can be unscrewed and cleaned and put back in. Plus many farm and home places carry them and are under $10. For that matter have you looked to see if this site has them

Old, no I didn't. Be the tight wad that I am, wondered if I needed to spend any money on it. Haha.

Is this the strainer you're looking for?

Yes Sir, I believe it just might be. Thanks a bunch.

Maybe not.

Based on your description of "[i:654c4848f0]occasionally just quits running. It's almost like you shut the switch off.[/i:654c4848f0]", the condenser might be bad.

You might consider replacing the failing condenser with a new one from NAPA.

Have purchased many condensers from various vendors and the NAPA condenser has been the most reliable.

Hope this helps.

Well the reason I said pull it off and try to clean it because I tend to try and save a buck if and when I can and I have cleaned those many, many times over the years

Thanks James, I'll get a new condenser before the mowing season begins. I primarily use this machine on a 5ft bush hog and tidy up field lanes/pasture areas where larger equipment doesn't get. Appreciate the input.

Pull that little strainer out of the carb...it is in the 90 degree elbow where the fuel line enters the carb. Carefully blow it out/clean it and re-install.

Also, Check the battery connections. Ours would die intermittently and eventually figured out that it was due to a cable with the wrong terminal end on it. It would vibrate around and get just loose enough to cause a problem.

The strainer in the link is wrong. That is for a Ford - Not a John Deere. Your's uses a compression fitting. Available from Roberts for $19. Brake cleaner will clean up your old one just fine.

Next time it dies, remove the carb drain and see if you have a steady flow of fuel. The strainer is easy to remove and clean. You may also have enough debris/rust in the tank that the supply of fuel is being choked off.
Once that variable has been eliminated, see if your coil is hot to the touch. If you are running a ballast resistor, it may have failed. This would only apply if you are using a 12v battery. If still 6v, then ignore the suggestion.

To clarify, I discovered that the battery cable going to the starter was built with a terminal end intended to go on a positive battery post, as you'd expect since most systems are negative ground. Since these tractors are positive ground, that terminal end couldnt quite clamp the smaller negative post hard enough. It seemed tight enough, but it wasnt.

As soon as I replaced the end with a negative terminal that properly fit the battery post the intermittant dieing/no-start condition went away and has not returned.

Thanks MrPrecision. That makes some sense as it has always done it when in motion. The last time it happened, I removed the sediment bowl "screen" and cleaned/blew it off with an air compressor, then
replaced the gasket and re-installed it. It ran for @ 20 minutes after that, but one wonders if that was it... It can sit and idle for 15 min and never skip a beat.

Thanks KY Patriot, I'll check battery connections too.

Old, I have a place near Lebanon MO. Wonder if I could catch up with you some time?

Did you check the flow from the gas tank? My 1010 had a few pine needles in the tank that found their way into the fuel tank outlet into the fuel bowl. You couldn't see them with the fuel bowl and screen off. Mine kept running like garbage and then would just die. A little while later, when fuel returned to the carb, it would start up and run good for a few minutes. I drained all the fuel, took the fuel bowl off the tank and found my issue. I blew out the tank, put it back together, no issues since. I however second James Howell on the condenser. I have seen that be a cause as well. It is always good to have two on hand.

Thanks Hotflash, I'll get this figured out thanks to all the help from YT. GREAT place.
