Hi guys I am just new to this forum. I have a 1997 MXZ 440 fan cooled and went to fire it up for the first time this winter and it will run with the choke on but has a very low idle and bogs down with giving it some gas, and when i take the choke off it will fun for a little bit then die like it is running out of fuel. I put some gas line anitfreeze in it yesterday to see if it would make a difference and doesnt seem like it has. Just wondering if it is a carb problem or something elsle. I have owned the sled for 6 years now and havent done any maintenance on it since then, just plugs which I just put in a new set last winter. I did pull the plugs and found that one was dry and the other was wet. Thanks in advance for the advice.

Pull the carbs and clean them! How old is the gas?

I put 20 liters of new mid grade gas into it yesterday, had next to no gas left in it when I had parked it in the spring.

X2 on carb clean. There is a tutorial in the how-to's section of this forum.
