WD-45 -- no fuel and no spark

Posted by Will Herring on May 22, 2020 at 16:14:07 from (50.106.232.40):

Hey there YTers, it's been awhile! I've been trying to help a relative get their WD-45 (w/ loader) back up and running... Started on it a few weeks ago by pulling the carb. I took the TSX 464 carb apart and have cleaned it up and not much of note inside sans some rust on the drain plug and a bit of gunk on the tip of the main power adjust needle (it's a Type-C with the adjustment in the bottom of the bowl).

But today I went out and worked on the tractor some more and put a known good inline spark tester on plugs #1 and #4 and got NO spark. So something is amiss there (however -- this tractor has sat for 8-10 years without running). In addition, I found out there was no gas coming out of the tank when you'd open the petcock. So I pulled the tank.



This tank paint job makes me suspicious of if this was original or a replacement...



Look at that nice original orange paint underneath the tank though -- the true original WD-45 color?



Anyway -- got the tank off and felt something slosh around inside of it. Took me about 15 minutes to fish this out, I think somebody broke off a measurement stick in the tank years (20? 30?) ago, and it's starting to have the paint slough off and the wood break down and it plugged up the sediment bowl valve and I think it must've been a bit caustic because there's horrible pitting in the zinc casting internals and the stopper valve is rusted and corroded. I have a new one on order from Steiner. Was quite a surprise to me, haha.



Also, as a side bar, working around a loader frame is a pain. Getting the tank off was a bear. Could just raise the hood enough to hit the loader frame to slide the tank out the back and over the bracket where the traction booster and hydraulic quadrant run to.



So anyway... Carb is cleaned out and just needs the gasket put in and back together. Gas tank is in the garage waiting for me to clean it out some more. New sediment bowl and fuel valve assembly is on order.

And then I need to figure out what's up with the electronics system. Where to start? The ignition switch? The coil? Points? Condensor? Easy diagnostics to tell what component may be biting me? The tractor turns over okay on 6V, but doesn't "fire".
