John Deere 14SB Not Drawing Gas/Fuel
My 1996 14SB started stalling so I took off the carb and cleaned it with spray carb cleaner. It ran fine after that, though a little slower than when it was brand new (probably about 80% speed judging by how fast it's propelled) and I mowed about half an hour with it to make sure it stayed running well before putting it away.
Well maybe I should've left well enough alone, but I thought it would be a good idea to replace the brittle original fuel line, and add a fuel filter while I'm at it. After replacing the line with generic 1/4" line with one of those button shaped filter that seems to sold everywhere, and using good screw on band clamps, the mower started stalling after running for a few minutes. It would restart easily if I wait a couple of minutes, but stall again after a couple of minutes. Did this a few times and figured maybe I have a bad filter, since I don't see how the fuel line and clamps could be causing this problem.
A few days after that, I replaced the filter with a John Deere unit made for a riding mower that cost $12 from Home Depot, seemed to be the best one they had. The mower ran for a couple of minutes with this new filter, and the filter was getting half full with gas, line the old generic filter was, but then started stalling. I noticed the fuel level in the filter was getting lower each time I restarted the mower and it stalled after less than a minute each time. Restarted maybe 4 - 5 times. Now it won't start at all, and there is almost no fuel in the fuel filter on the tank side (filter has a clear plastic shell). Funny thing is I think I can see the cavity inside the paper filter element, on the carb side, still is almost full of fuel, because the paper paper element is slightly translucent when wet.
I don't have any idea why it's doing this, but then I know very little of how these engines work, so I might be missing something really simple. Would really appreciate any help on this. This is a really nice mower and has a lot of life left if I can get this problem straightened out. It doesn't have all that much wear, probably 20-30 hours each year and I changed the oil at the end of each season. Sorry about the long post, but wanted to make sure you have the information you need. Thanks for any help.
