95 7.4L wellcraft.4 barrel Webber. 2 weeks ago I pulled her out to get it ready for the season. I had put stabil inb the gas before the parking her. I did not fill the tank to the top, just added stabil.. Upon trying to crank her, i ran the battery down without any hint of firing. I opened the throttle to look down the carb and see a pool of fuel sitting in the intake manifold. I suspected bad gas, so I opened the throttle WFO, towed the boat to the pump and added 10 gallons of fresh fuel, let the battery charge 4 hrs, put the muffs back on and within 5-10 cranks she started and I let her run for 15 minutes or so.
Fast forward 1 week, tuesday.....i add 6 more gallons of fresh gas and go to the lake.....nothing. no single cylinder fire. I treat it like fuel starved and pump it several times. Nothing. I treat it like it's flooded, nothing. I now have a pool of fuel again in my intake.
So I tackle this job again this weekend friday. Spark: I've got blue spark on all 8 plugs. I spray a shot of starter fluid in the intake and get a fire or 2 then nothing. I crank until again i have a pool of fuel in intake. I think now I have a float that's not working. i take the carb apart and set the float to 33mm per the manual. I check to see if the needle/seat are functioning and they appear to do the job. The fuel inside the bowl shows no signs of water but i can't say it's an overwhelming gas stench. I put it back together. I dry the intake thoroughly using a paper towel to absorb then a leaf blower to finish up to make bone dry. I reinstall carb, put a shot of ether, i get one or 2 fires then nothing. I do this same procedure 2 more times checking the carb for anything suspicious and still nothing other than a single hit after a shot of ether.
I'm stumped. My only other thought is bad gas settling to the bottom and that's all I'm getting to the carb.
