88 Marathon won't srart

[mrwrenchman]

Ok guys here is the problem I am having. My wife was driving around our yard on fire ant duty . I heard a pop from the cart and it stopped running . I checked the gas tank and it was empty . I filled it up and cranked and cranked still no start . I pulled the spark plug and changed it thinking it went bad . While I was at it checked the spark , no problem there lots of spark , also good compression . Next I checked the carb took it off and went through the whole thing , took the manifold off and looked at the reeds and they were moving as the engine turned over. Put it all back together and still no start. Tried ether in the carb and still nothing. Please don't tell me it blew out the crank seals . I rebuilt the hole cart about a year ago and it has run great with no problems . Any help would be greatly appreciated I am about to pull the little hair I have left out . Don
