I checked my compression this summer all 130 psi. I started it but ran f up. So I removed carbs and there was that white gunk in it. Cleaned them all and R/I them started again and ran f up. Could tell one was not firing. Could this have happened from just starting it those couple of times? It did not run for a long period of time only a minute or 2.
I doubt it, whats compression at now?
seriously doubt it for a min or 2 but if it didnt have any oil in the cylinder, it could stick a ring that fast

What do I do next? I removed the cyl and the piston still looks good.

Why would it not get oil?
You pulled the jug!?

yeah I did
First, make sure you've got spark at that cylinder. If you do and your getting the plug wet then that same plug is working it another cyl when you swap it, it's not fouled and I doubt the needle and seat are flooding it out. Possible, but slim I'd say.
Is the pipe not getting warm with it only at an idle, or varied rpms for a few min?
I'm guessing you've got a clogged pilot or something in that circuit, assuming again it's got spark.
What did you do to clean the carb? Spray can of carb cleaner is not thorough. To do it right, go to auto zone or somewhere similar and get a gallon pail of barrymens chem-dip. Strip the carb completely down, remove all the jets, air screws, etc and dip it over night. THEN use the spray can of carb cleaner and shoot it through all the passages as well as each jet. You'll have wanted to dip the main and the pilot also btw. After that follow up with compressed air in all the same places and reassemble. If you want to be anal hit the carb with WD-40 when it's all together to make it look pretty.
The slime you said you found is fuel stabilizer I'm guessing. If it's been put in the tank at too high of a ratio stored, it'll make a real mess.

It was getting plenty of fuel when I pulled the pipe off It was full of fuel and I was getting spark. I also removed the carbs and cleaned them good just like the instruction on the tech pages that mrviper had posted.
Hmm.... pipe was full of fuel, or just the float bowl?

the pipe

If the pipe was full of fuel, you have spark, and the piston/cylinder looks fine, its either a bad reed, or most likely a obstruction in the carb. Had the same problem last year on a sx I went thru for my dad, it was a dime sized piece of paper towel that went in with the float bowl, clogged all the jets.
