fishinwrench Posted November 30, 2012 Posted November 30, 2012 Yep, your first start after a period of sitting is always gonna be heavy on oil. The fuel in the carb bowls evaporates through the vents leaving the oil behind, then when you pump the bulb it adds 50:1 mix to what is left in the bowls.... so you are always double-oil on a first start after a period of no operation. It will clear out in about 4-5 minutes or by the time it warms up to operating temperature. If it sets long enough the oil will turn to molasses-like sludge that the fresh fuel can't disolve and it clogs up the jets and emulsion tubes (regardless of whether you used stabilizer or not).... Or in the case of an EFI 2-stroke, clogs up the fuel pump and components of the vapor separator and injectors. This is a really good thing cuz guys like me have to eat and pay bills too

Im assuming this method will work on a bigger motor like 150 mercury black max?
fishinwrench Posted November 30, 2012 Posted November 30, 2012 That's the old timer theory, yeah.... to run the carbs dry. Its a BS theory though because unless you have only one carb and play with the "choke" (which most modern outboards don't even have anymore) so it sucks more than half the bowl dry, it really doesn't do what you think. All it really does is speeds up the time it will take the always remaining oil to dry out and get thick. The more liquid fuel there is in the bowl the longer it takes to evaporate completely. See what I'm sayin'? Which will turn to a thick goo quicker..... one droplet of oil, or a teaspoon full? It only takes a tiny little droplet of thick goo to partially or completely plug the HS jet and emulsion tube in the bottom of the carb bowl.

I'm in total agreement of this, there's always gonna be some left in there. I've started using the marine stabilizer, although not for sure it it's any better. I have an ETEC that I worry about doing the same thing, I've kept it and my old boat, but other than duck season, it sets up since I got the River Jon. There's no such thing, as a bad day fishing!
LittleRedFisherman Posted December 2, 2012 Posted December 2, 2012 Not to butt heads with GM, but his judgement calls are questionable lately. lol, hey you can't fault a guy that's determined to get to his fishing spot.... There's no such thing, as a bad day fishing!
fishinwrench Posted December 2, 2012 Posted December 2, 2012 lol, hey you can't fault a guy that's determined to get to his fishing spot.... True that. At least he caught some decent fish. I have torn up plenty of stuff trying to get a boat into certain spots .... and then got blanked. One extremely windy day on Mark Twain I got the bright idea that if I pulled the plug and let some water in the boat to weigh it down that I'd be able to hold on a brushy midlake hump that we'd been killing the bass on (anchoring was against the rules). Assuming that I'd be able to bilge out the water when I had a strong limit. Well I did get a limit but the bilge pump crapped out. Had nothing bigger than a pork frog jar in the boat to bail with and everytime I tried to get the boat underway the nose came up making all the water go to the back and try to sink the transom. Had to idle back at a snails pace (late) to the weigh-in, 9 miles through 2 ft. wind rollers, then burnt up the clutch in my old 3 on the tree 6cyl. chevy trying to get the boat far enough up the ramp to drain it. So I'm no stranger to failed judgement calls.
Guest Posted December 3, 2012 Posted December 3, 2012 Take a look at this yummy concoction... looks like a bad pi$$ test!!!
LittleRedFisherman Posted December 4, 2012 Posted December 4, 2012 Wow, that looks bad!! Wonder how long that had been in there? There's no such thing, as a bad day fishing!
fishinwrench Posted December 4, 2012 Posted December 4, 2012 He topped the tank off and put Stabil in it November of last year. It was "running fine when he put it into storage".
