carb question?

[fishaholic]

Hello guys I have a question, I'll try to post as much info as I can, is it possible for floats inside the carbs to get stuck in the up (full) position? The reason I ask is went out yesterday, the motor started perfect, idled perfect and when I went to give it throttle it did'nt go, we stopped at the marina and put a new filter new water seperator and still the same so we took the drain plugs off and when you prime the ball fuel flows out the 2 top carbs but not the 2 bottom ones but when you disconnect the fuel line that goes to the 2 bottom carbs and prime the ball fuel flows and the ball primes easy but when you connect the lines back the ball is real hard to squeese also while on the water when you give it throttle and you look into the carbs you can see fuel flowing out of the top 2 1993 115 mariner 125 compression last time used was 3 weeks ago, always use that ethanol stabil treatment, gas tank is 1 1/2years old aluminum the carbs were rebuilt 5 months ago, I'm aware that this motor has that 2+2 thing but should'nt fuel be going in the carbs sinse its coming out of the fuel lines, when I spray break free down were you connect the line it just shoots back and doesen't even come out of the drain, I just want to be sure before i take the carbs apart to check, thanks in advance.

Yes, it sounds like the needle is stuck closed.

Re: carb question?

yes it is possible that your needle got stuck this is a very common thing i would suggest running some "sea foam" through it which is a fuel additive that is made to clean out the carberators and also clean carbon build up in the exhaust ports. You can try tapping the bowl of the carb with a screwdriver handle to losen it temporarilly but in the long run you will need to get the carbs cleaned

good luck!!!

Re: carb question?

if I take the carbs apart and clean them whemn I put them back do I have to adjust everything again, timing, idle ect.

Re: carb question?

when you take apart the carb you do not have to mess with timing. you will have to adjust the carb fuel-to-air mixture screw which is no big deal try running sea foam through it this should clean carb without having to even take them off. !!!
