Got my cub all back together and it will not start. I do occasionally get a backfire though. I found that I did not have the wires on correctlly 13
24 so I reinstalled them properly. I still have nothing not even the backfire anymore. The plugs are as dry as a fart. It seems as though the gas is not getting to the cylinders. My cub has an in-line fuel filter and it will not fill up with gas. If I crack the flange open o. The carb and allow air in, it will bring gas down through but as soon as you tighten the flange again, the gas flow stops and will not go down into the filter then into the carb. Can anybody help me!?

Thanks, Cole
 
If you have one, take the plug out of the bottom of the carb, if it doesn t run a stream of gas out then you know where to start looking. The fastest way I have found to quick check is spray starting fluid in the carb and try to start it. If it runs on starting fluid you know it is a gas problem.(1 can is a lot cheaper than burning up a starter.)
 
Your filter mite just be plugged enough with the fine dirt to not let enough fuel to pass. I use those Fram see thru filters to catch the fines the sediment screen doesent catch and they do get enough fines to slow down flow. After time i do remove them and replace with steel brake line but they sure do catch the real fine stuff.
 
Sounds like the float and/or needle is stuck in the carburetor, and is not letting fuel in.

That happens when you pull the carburetor off the tractor and throw it in a box where it sits upside down and dry for a while. The needle can stick in its seat.

You'll probably need to pull the carb, get the needle unstuck, double-check the float level. Just be warned if you're a carburetor newbie it might take you 2-3 attempts.
