Comments (1)check to see if your choke is sticking-common problem...See MoreJohn Deere STX38 black deck runs then dies
Comments (3)Cleaned and checked the vent cap, it is working fine. But did take the cap off and tried to start it, didn't help. Replaced the fuel filter two months ago, thinking that would be the issue, but still having same problem. Checked and getting plenty of fuel to the carb. Doesn't matter how long I leave it sit, it still cranks but won't start, and once I do get it started it mows fine for about 10 minutes and then just dies. No spit, sputter, just dies. I have flooded it a couple of times trying to start it. I have taken the filter off and tried to start it, that didn't help....See MoreJohn Deere jx75 not running
Comments (2)I agree that it seems like a HG. I got it running yesterday (weakly) but only if I had the air filter off. It blew white smoke from the carb, oil fill and exhaust. Bad news.......See MoreJohn Deere 425 - runs for 10 seconds and shuts off
Comments (7)Huh, kinda lucky it ran at all, I'd say. Must've been weak fuel pressure, but still functioning somewhat? I'm curious, but did you ever remove the original fuel pump from the tank and check it out? Your 445 has an internal pump (inside the fuel tank) doesn't it? I wonder if the filter sock had plugged up or come off and allowed the pump to suck up junk from the bottom of the fuel tank? Somehow, people always seem to get "crap" in their fuel tanks, leading to future problems. Glad to hear you came up with a cheaper fix with the automotive style pump. It may fail sooner, but it's hard to say. External electric fuel pumps typically fail sooner than internal ones due to heat. What most people fail to realize is that fuel pumps run/stay cooler when immersed in fuel. (That's really the only reason why they put them inside the fuel tanks in the first place.) My JD 322 has a external in-line fuel pump. The original JD pump failed after 12 years of service, and it acted much like your 425 did. I too, went to the auto parts store and got an inline pump that was nearly identical to my original one, for about 1/3rd the cost of what my JD dealer wanted for the same pump. How aggravating that was, that JD's price was so unreasonable! Anyhow, the only thing I had to change was the plug connector, in which I cut the original one from the old pump and connected it to the new one so that it would fit exactly as the old pump did. It has now been on my tractor and working great for the past 6 years with no problems. Yee-haw! Oh, the only other thing I was going to mention was this... These days, many small engines have electric fuel shut-off solenoids on the carburators. When they fail, they either fail partially - leading to power loss issues, or they fail completely - leading to no-start conditions. The way to check them is to remove them from the carburator and put a very short (and same thread) cap screw in place of them (with a sealing washer at the head of the bolt of course). If the problem "disappears", then you know you need a new fuel shut-off solenoid. They usually fail from heat, and so sometimes they will work for a little while until the engine warms them up a bit. I know this, because I've had to deal with the failure on more than one occassion when I used to work on Lawn & Garden equipment for a profession. Additionally, you want to make sure you replace the bad fuel shut-off solenoid with a new one, as it's what helps to keep the engine from backfiring when shut down at various different engine RPM's. Peace out!...See More- 15 years ago
