Before installing the new float I was noticing fuel dripping from the venture area. Would remove all wet plugs and clean, then spin engine over to expel excess fuel from cylinder's.Engine would generally fire up and run roughly, and i'd try to adjust it.But it would stall and not re-start with out cleaning plug's again.Engine was alittle low on oil due to a leaking valve cover.Have a oil change that I planned to do as soon as I got the bug's out of carb.Have checked oil every time before trying something, and it was still just alittle low as I caught it and fixed leaking gasket.When I say leaking from venture area, it seemed to be drippind from those hollow tube shaped thingie's on the venture.Didn't see a rise in oil level during all these attempt's to get carb right.I'm with Kghost on the yellow tube showing sign's of bad fuel pump, but the fitting on the pump appears to be blocked or stoped up.Maybe that's why it didn't give the pump problem away by filling with fuel.Good side of thing's is if it's the pump...that's fixable...lol Engine was running the best it has when this happened. seemed pretty smooth from jump just before the mix started spraying out of valve cover.Even then, the engine re-fired fine and idled good.If the carb was still the problem you'd think it be flooded after that.Oh. would it be ok to use some 15-w 40 to flush engine before using my mercruiser oil and filter.?It's got a Napa brand oil filter on it now but I bought the one recommended at boat shop when I got the mercruiser oil.Really thank you all. Feel like I need to mow you'r yard's or wash you'r boat's or something for all you'r help. I really appreciate you all...
