i have alot of gas coming out of impulse nipple and front cylinder with plugs out when i hit start button. rear cylinder has no gas flying out of plug hole when i hit start button. the return line is dry. is this a carb problem? how do i get gas out of motor?

Slow down....the MAG carb has a pulse pump to suck fuel into the carb (and into the cylinder.....there should be a pulse nipple (vacuum from engine), fuel inlet nipple, fuel outlet nipple on that carb. Which nipple is fuel coming out of?

Fuel will evaporate, so leaving the spark plugs out will allow the fuel to evaporate eventually. Are you sure it is pumping out fuel and not water?
 
BE VERY CAREFUL AT THIS POINT, you have an explosion/fire hazard. What likely happened is your needle is stuck open and gas flowed down the mag carb's throat and into your engine. You can maybe use those little rubber siphons they sell at harbor freight. They look like a short, fat primer bulb for outboards. Usually come with clear line. I'd avoid ANYTHING that can throw a spark. You can remove the mag carb (using hand tools) and reach the hose into the engine. You will have to turn it by hand until the RV plate moves to the open position. Once you can't get any more out, you'll have to get the rest I guess by cranking the engine over. I'd wet it down to dilute the fuel to further reduce risk of fire. Be sure to have a fire extinguisher nearby and a plan in case it does catch fire. I saw a dude on one of my fb groups who went to the hospital after checking for a spark went wrong for him.
 
i got the gas to stop spraying out of plug holes but a little still comes out of rv plate. will it eventually evaporate? how do i know when i can put plugs in and start. im checking out carbs now
 
Ty for all your help . It was the needle seat. Ski started and runs awesome.
Easy there.....I assume you mean the ski runs "awesome" on the trailer??? Yeah...they tend to do that (makes you crazy thinking you got it). The real test is in the water.....mine tore the trailer up, great starts, runs hard and strong.....first time on the water and it fell flat on its face....mofo,mofo,mofo...what could possibly be wrong.....had to re-do the carbs until I had her dialed in just right.....not saying you won't have better luck.....just be aware that these machines love to taunt us....hahahaha!
 
lol, great response!! they are trailer ferraris.. ill give it a shot on water.
Indeed...I have uttered a SIGH or two with these machines.....;):thumbs-up:

That is WHY you NEED a couple EXTRA skis around, so if one craps out....use another. NOTICE: Lots of posters on here seem to keep a freakin "stable" of machines in their inventory - :money-mouth: mo money, mo money, mo money!
 
Did the job!! Works great. Took about 5 minutes before it would take full throttle. I putted around and eventually it must have burned off excess gas.
