So I have an 85 22R in my 81 Toyota. Everything was grand until I went wheeling in it this past saturday. Had to ford a couple pretty deep holes and as one would expect, lots of stuff under the hood got wet.
No big deal right? Pull dizzy cap off, make sure everything is dry, check all the plug wire connections and stuff and make sure everything is kosher and off we go.
As we get to the end of the trail it starts running like absolute poo. Takes cranking on it forever and using carb cleaner in the bowls to get it going, won't run at all unless choke is pulled all the way out. (Got a 32/36 DGV Weber on it.) Barely make it home.
Check everything again, all connections are good. Dizzy is dry. Scuff the end of the rotor and each of the terminals inside the cap. Pull the plugs and check them out. They are a little carbon fouled from the rich condition of having to have the choke pulled all the way out, so I clean them up with some emmery paper. Switched out the plug wires for some other ones I had laying around the shop. Cant find any vacuum leaks when I do have it running long enough to check. I tore apart the carb, everything looks to be ok to my totally untrained eye. Ran a welders tip cleaner through the jets and used a ton of carb cleaner to get out any junk that might have been in there.
Stuck the carb back on, got it to start off of some carb cleaner, with choke all the way out still. Still missed throughout the RPM range.
Also, while driving down the road at a steady speed, it will misfire and the tach will jump all over the god damn place, and the truck lurches pretty good. Get the occasional back fire. Can't tell if it's from carb or exhaust end though. Probably some of both.
As a side note, everything else seems fine, normal oil pressure, temp gauge reads where it normally does, alternator is still putting out the same amount of juice it always has.
Looking for some advice on what to look at next. Thinking possibly a bad igniter? How do I check the damn thing before I go and drop the $110 or however much the damn things cost? I know they aren't cheap.
This is my daily driver so I really need to get it back on the road.
