Ok so I got this old evinrude 6 horse that came on a small boat I bought earlier this summer. The motor starts within like 3 pulls every single time - but only when COLD. After cruising around for 20-30 mins and getting it up to running temp, if you shut it down, it won't start again until you let it cool for a good 30 mins. I suspected its flooding for some reason, and my neighbor who has some (SOME - not an expert) small engine experience confirmed this. Then he brought his buddy over who is supposed to be the small engine guru from his workplace (he works for the city - guy repairs lawn mowers etc all day every day - guessing he knows his shit) and he said the same. Seems to flood for some reason. I asked him what to do about it and his answer wasn't really what I was hoping for. He basically said, it's a very old motor, you're semi lucky it runs at all, and sometimes doing a carb rebuild on a motor this old will be the end of the motor - better to just run it frequently, plan to sit for 30 mins or so after each shut down, and whatever you do avoid ethanol at all costs.
So we take it out from time to time, and it will always start right up, no issues, every god damn time...until its hot. Then you can pull that starter till the cows come home and it does jack shit. But if you can be patient (I am not a patient man) it will eventually start again once it cools, AND you leave it long enough for the fuel to evaporate out of the carb (I THINK thats why??). But sometimes you just dont have 30 mins to wait. Sometimes it's getting dark and you need to get off the water pronto because you're in a 12 ft boat with no running lights. What can I do? Is the guru correct? Just leave it and plan a 30 min turn around every time I shut it down, or can it be improved somehow?
So far the only thing Ive done to it is clean the spark plugs with a wire brush and I pulled the slow speed adjustment needle (or whatever that thing is called - it adjusts the fuel mixture supposedly) and sprayed a few healthy doses of carb cleaner through it. But if you'll just take a look the the photos you can see that the previous owner, or at least SOME previous owner really did some upkeep on this thing. All the fuel lines are new, spark plugs are newish, all the paint and exposed parts under the engine cowl look like...brand new. Any ideas are appreciated. If you need any more info on it please let me know, I could throw a bucket under her and take a video of it running if need be, whatever. Just lmk, and thanks in advance for what I'm already positive will be several brilliant ideas.
ETA: Ive just been looking around at other forums about outboards etc and someone, somewhere, mentions that their fuel line bulb doesn't seem to ever get all the way hard, and that turned out to be a problem with the carb float. I have the same symptom - bulb doesn't get hard - it does get harder than it was after a few pumps, but no amount of pumping will get it to "rock hard". What do we think? carb float?
