So I got it running on the trailer, took it to the lake, started right up. Idled around for about ten mins smoked a lil (premixed gas just in case pump wasnt working, figured wouldnt hurt anything) then took her out to open water. Ran good for about ten mins then started to backfire , lil @ first then more once I tried to idle around again. Then it wouldnt idle anymore. Then it wouldn't start. So took it back home. Took the fuel line lose from the carbs while turning it over and fuel comes out do its getting fuel to the carbs,i think. Im hopeing that the carbs just got to much oil in it so I'm gonna rebuild them. Been awhile since they've been ran. Any ideas what may be going on?
