Do I need to do anything specific to run premix, or do I just not fill the oil tank and mix it with the gas instead?

I checked the compression on both cylinders and they're both about 80 psi... Definitely not good. Can someone please tell me that there could be another reason for low compression besides worn out Pistons.. Head gasket possibly?

Last time I checked it was still flexible, the new tubing has only Been installed for about a month and a half... I will double check it. Thanks!

My Gtx starts right up in the water, I'll check the compression anyway, I'm really hoping I can rule out the low compression idea. If I take off the rotary valve cover, are there any parts that fall out or off? I know I have to use something to mark the timing, I just want to make sure I don't...

Thank you for giving me more options to check! If it has low compression, would it not rev up at all if the impeller is in the water?

I changed the coil, the wires, and the plugs. It ran good for about 5 seconds and went back to bogging again. Once again engaging the choke while its running does not do anything helpful. I also did try to mix the choke with the throttle and that doesn't help.

The petcock was bypassed, the fuel line runs directly from the tank for the time being. Any gray tubing that has gas run through it was replaced with green tubing.

Also when I had the carbs apart, I took it all apart and I cleaned them out. Jets, diaphragm, filters, and the pump.

if the choke is engaged in any position while it's running at any throttle position, it will bog down if not shut off. If I crank the engine over with out starting it and I have the choke fully On, when I go to start it up with no choke, and give it throttle, it will rev up and take off like...

Engaging the choke while applying full throttle doesn't help, it only bogs the engine down, even if choke is halfway.

Are you talking about in the carb? Would a lean big get better when the choke is applied?

The o ring in the water separator/ fuel filter looks like new. The ski runs perfect on the trailer, I don't see any gas leaking in the hull so it can't be a leaky line... My next attempt is to put a different coil in and see if that helps, I'll also go over my ignition wires to see if there's...

It is that the plastic twist off thingy with the mesh screen in it, correct? It seems like it would have an o ring, regardless I haven't checked it but I will when I get home today. It's a real Bummer not having the ski working right in the middle of summer!

I had this issue a couple months ago, I went through everything I possibly could. Here's the list: -removed and cleaned carbs and inner carb filters (carbs weren't dirty or worn) -replaced the rectifier -changed the gray fuel tubing going to the carb to green with inline filters -bypassed...

I'm not sure what happen, but my friend and I went to test it again last night and there was a strong spark on both plugs. I didn't change anything and i did the same procedure as i did in the past. Thank you for the input everyone and i will keep your ideas in mind for the next ski that loses a...

-I did cut 1/4" off the wire ends and there was no luck, I changed the ignition and that didn't work either. -This clear connector you are talking about is in the gray box, correct? The MPEM is the ignition coil itself? I will be looking at the ski tomorrow since I have off, so hopefully I...

There is two posts, one to start and one the safety lanyard goes on. The ski won't crank without the saftey post pushed in.

Most of the lines were replaced with green tubing, I remember seeing a small section of gray tubing. The ski is stored at the shore for the winter, so I will look at it when I am down there again. If the carbon seal is bad, wouldn't the ski leak water inside from where the driveshaft exits?

No, I do not remember the specific location but I believe it was off of exit 6 or 7 on the turnpike.

This is my first post, so if i messed up please let me know! Ok, I have a 1992 seadoo XP that me and my friends bought for $100, knowing it needed a drive shaft seal and carb cleaning. The seller was very helpful and informative and didn't seem to be hiding anything. Anyway, we attempted to...
