it sound like just the starter too me.
1996 GTX - Idle jumps 1K to 2K rpm .... let go of throttle and dies?

He's not saying that's your problem. I have two of those skis and they made that same sound when the starter became dissengaged from the flywheel. If that were my ski I'd shut the fuel off and pull the spark plugs and spin the motor over and see how much fuel comes out. Then I'd put a little fuel/oil mix down the spark plug holes, Gap and insert new plugs and go for it. Don't forget to turn the fuel back on.
Did you do a compression check yet? If you don't have a gauge beg borrow steal (j/k) a gauge and get that done. Don't play pin the tail on the donkey, it could save you alot of money in the long run.
I have the same ski. Gap on NGK BR8ES should be .5-.6 mm or .020-.024in
Yes, same mix...no more than 1/4 teaspoon.

Sethsmind you forgot one....dont forget SBT Motor installed in the beginning of all this. This thing has been a nightmare. Im wondering if that pressed in Brass fitting slipped. Remember the last time it was in the timing was way out... Dialed in the timing and ran great. Met you at the beach and changed plugs fired it up......I rode it around hard for about 15 min...then I left and you guys took off on it and had problems again. Im sure it will get figured out.

Was ski at your store getting fixed.
I'm still waiting for compression numbers.
But with new info I'm leaning to RV gear.
Can't engine come out and back to SBT for inspection??
Yep it has been at our store. I have to look at the tech report again but I think he still had perfect compression. When I met him at the beach and cleared it out (it was loaded up very bad)...and threw some fresh plugs in it, it ran great. As a matter of fact when I took it out, it was way smoother and better running then my GTX ever was. I put it threw a few different situation trying to get it to act up. Idle, Mid Throttle, wide open...wide open from a dead stop....shut it off and re-started perfect several times. I gave it back,and him and his brother got on. I watched them leave, then I got in my car and left...The next day I got a call that its not right again... I think this ski just has a gremlin in it LOL!! After the compression test the next thing we are testing is the timing again...if its way out then he has bigger problems

Hopefully he still under warranty..........
He should be in good hands if your trying to solve issue.
One other thing I wanted to say. The starter issues he had, was a problem with the flywheel in the ski having the wrong number of teeth.. If I remember right we put the correct flywheel in it at no charge. Im just trying to help him get this thing on the water so he cango enjoy it with out a bunch of issues

I second a compression test, anytime I check an engine I run a simple compression test on these, takes litterally less then 5 mins to do.

Hopefully you can get him sorted out and make things right.
Really sucks though.....
Is that 40 or 140??

By the way Rampage, Thank you for everything.
In and out of the shop. I think you and I are the
only ones who know the amount of time and $
to get this ski on the water.
UPDATE:
Ski has been rebuilt by a Pro.
Everything is in 100% Like new working condition.
It is a NEW Ski!!!! All said and done $4000 into it.

Dude that totally blows.
Unfortunately that happens. Once a engine goes where pistons are needed the bottom should of been taken apart and opened at least.
For what you spent on the top end you could of gotten a engine exchange?? Don't know who dropped the ball there.
You can take engine out your self its not that hard. Then its take the top off again and put on another bottom end.
You can find new bottom end w/cases for ~500 bucks.
Most of the money you wasted was by leaving it to the dealer. Carb cleaning
All those repairs could of easily been done by you with a little time.
So Q is what are you going to do??
What are you out so far? The 2k in dealer repair plus 500-600 to get it running again your still over 3k
but under ??
Its still salvage b/c ski is near mint and you'll have it for a long time running right with this site.
Another idea find a used 100 core send that in to sbt for the 1000 plus and have a 2nd engine sitting on the side as spare or sell it and get some money back.

Here is its location in the case.

What they did what only the top half of the engine where piston goes up/down in the cylinder.

Look at it as a learning curve. As long as the top end is fine then its a matter of swapping parts.
Dude I really feel bad and would be feeling the same way.
Whats with the different BS oil ratios. Like that is going to fix something mechanical.
Theres nothing really left to do. The dealer is washing their hands b/c the complete engine was never exchanged in the first place like this.

It is buyer beware when you trust someone else to work on your things.
So now you can remove just the RV gear for 100 bucks but the engine has to come out to replace. But all the shavings from the gear are in the crank bearing waiting to cause damage it not already.
You have one of two choices.
#1 how bad you want to ride? Go find another 2 stroke b/c they are going for cheap on some places ready to ride with everything rebuilt. You could get some money back by parting it by pieces non working skis w/trailer go for ~500 bucks.
#2 Spend the extra money and rebuild it. But cost of ski is exceeding getting two :banghead:
#3 Do what I did buy a used working engine and pray....

It already had a pretty new SBT bottom end..everything checked out when top end exchange was done. Yes that 40 psi on one Cyl. Sethsmind took the head off to find a broken piston... SBT and BRP agree it looks as if a Timing issue , or lean problem, or wrong plugs caused it. I know he never put in the wrong plugs. I do know it had too much oil in it and that can cause a lean condition, because more oil less fuel.......but It def has a timing issue. I think SBT should be paying somthing to have this taken care of. I do agree also that he paid for a carb job last time, and that clearley was not the issue, so I got him a full credit on that. I did note the last time that ski was out of time and the motor may need to be taken out for the repair
man, i read the posts, new reman engine is 845.00 http://www.shopsbt.com/sea-1996-gtx/40-107.html -- you can replace it in a few hours, --
