Hey group, I followed Dale's suggestions and installed champion plugs, gapped correctly. The engine started within 1/2 a crank and ran very well this morning (when it was cold outside). Had a nice light gray smoke and no oil at the exhaust manifold joint. This afternoon when I went out to start it, the engine starts and will run but runs very rough and as soon as the choke is pushed in even 1/4 inch the engine dies. I've tried adjusting the main jet (the whole thing started with a carb rebuild) and the full load screw, but haven't been able to get it to run. I set the main jet at 1 1/2 turns and the main load screw at 1 1/4 turns, and it ran good this morning when it was about 40 degrees, but now it's about 57 and it won't run.

One thing I did today was put a 6" extension on the fuel line because it wasn't reaching the new filter head connection (with the new filter head screwed in, the old fuel line didn't reach). I used a black flexible fuel line and clamps. I didn't think that would change the way it runs but I could be wrong. In either case I have cut the old steel line and put the black flexible line on in the middle to extend it.

I don't know what to do now. The battery keeps running down because I'm cranking it to death trying to get it to run long enough to figure out what's going on.

I have the battery on the charger so I guess I'll keep trying until I figure out why it won't run unless the choke is on 100% choke.

Any suggestions would be appreciated, and thank you Dale and others for your advice. The new plugs seem to have fixed the oil out the exhaust.

Vic,
I think your problem isnt in the carb. but in your ignition system.I would suggest you change the points and condenser in your distributor or mag.if yours has one,and I will bet youll have no more problems.If so,try changing the ignition coil.If you have a mag on your tractor youll have to order the coil through a tractor supplier.If you have a distributor you can probably get one through most auto parts stores.I have seen this problem many times before and it is usually the ignition system.Hope this helps!!!

Here's something weird... I charged up the battery again (it's shot after the last charge - it smoked while cranking so it's time for a new battery) and cranked the engine over this morning. The temp outside was about 38F. The engine fired right up and ran strong. I idled it for about 10 minutes, adjusting the fuel inlet screw trying to get it to run with the choke pushed in... every time I push the choke in even 1/4 inch the engine starts to die. It's running well enough now (and no oil out the exhaust!!) that when it starts to die if I can get to the choke and pull it out the engine will pick back up and run.

I increased the RPM with the throttle lever and it started to run very rough but continued to run. It's idling very well now, with the choke all the way out. I'm going to clean the packing in the air cleaner to see if perhaps it's clogged, but if you all have other ideas about why it'll run strong but only at idle with the choke lever pulled out I'd appreciate hearing them.

It's supposed to warm up into the 60's later this week. It will be interesting to see if it runs as well when the weather's warmer.

Still t/sing but have to get a new battery now. I'll report back if I stumble onto something.

If all else checks out I think it must be in the carb. When my brother started up a WC he had put together it did sometihng like you describing. We took the carb apart again and I spotted a passage from the choke area that went back into the carb bowl area that was filled with mud. It was so even with the wall of the air inlet around the choke that you had to look to see it. The only way I noticed it was by chcking where each passage inside the carburator went, this one seemed to deadend, looking harder I saw the mud. Then the tractor ran perfectly.

Sorry if I'm repeating earlier suggestions.

Check your air cleaner if you haven't already. My WD45's wire doughnuts had been turned into adobe bricks by the time I bought her. Don't know how she was breathing at all. For a quick check remove the rubber hose between cleaner and carb and see if she runs better.

David_T, I took the hose off the air cleaner and ran the engine (it's starting real good and not leaking out out the exhaust anymore) but got the same results - when I pushed the choke in even a fraction of an inch the engine started to die.

I revved it up to a higher RPM and pushed the choke in a little - lost RPM and started to die.

So, I guess I'll go back into the carb and check all the seats and needles, and I might as well replace the throttle shaft while I have it apart because there's a little side to side play in it.

I'll let everyone know what happens.

Take the plug out of the bottom of the carb and with a can or bucket check for a good flow.

That was my first thought, too, Jerry. Vic, you might have shaved some of the rubber off of the inside of the rubber hose when you slipped it on the steel line. You will likely find the culprit at the oopening going to the needle valve by now. There might also be a problem with the new filter head... I'm assuming that is different from your morning run. Good luck and keep us informed.

Greg

Did it run good before cutting line? and after putting in rubber hose it doesn't? Did you get some rubber in the fuel line as you slipped the rubber hose over steel line, or the inlet to carb? check to see if you have full flow of fuel from carb for more tyhan 10 seconds
