YZ426...at wit's end!

I replaced the cleaned carb and changed the spark plug...twice. I checked for spark prior to putting them in and they gave a spark. I kick and kick but I get no fire at all. I am at my wit's end with this. Can anyone offer some advice on this one. Thanks!

With the air filter off, can you see the AP squirt fuel when you pump the throttle? Is the fuel on? If you open the bowl drain screw, does fuel come out?

Either way, you seem to have narrowed it down to something carb related, as your problem changed once you worked on the carb.
But as already mentioned wouldn't hurt to check valve clearances as well. I've seen guys who couldn't get their bikes to start no matter what they did because of valve issues ( on CRFs in most cases - surprise suprise - not the mighty WRs) .

I also had that problem with my WR this past summer. I bought a rebuild kit for it for like 5 bucks and the local bike shop. They had it in stock. It took me like 15 minutes to fix. You just have to make sure the seals are clean and fitten snugly. The old ones didn't even look bad, but they had gotten a bit hard and started leaking.
