Thanks everyone for your help. I have a lot to learn about the engine. I can't even tell you guys what you would need to know in order to help me, so in that sense, I am useless. I went out today and it ran better. The only iffy thing it does, is after releasing full throttle, sometimes it...

I picked it up from the shop today, I had a stock head put on. It's a 760 engine, but I really don't know to much about it, I am learning as I go. It has aftermarket air filters, and pipe. The shop said the carbs are good and don't need a rebuild. Today was a rainy day, but I went out for a...

I Just got the 90 superjet with a 760 engine out of the shop for a top end rebuild. He said the bottom end was still good. He rejetted it to ( I can't read his writing very well, so i'll try my best to write it here so maybe someone can make sense of it)...1.5 N+S, 256 spring, 130 main, 70...

Alright thanks man. I'll read more about it and run it by my mechanic. In the meantime, since it runs ok at a lower altitude, I'm going to lake Elsinore today. I've never been there before but if anyone is going today, lemme know.

Well shoot, after reading about the pop off, I'm wondering if my mechanic understands the carbs in the first place. A few weeks ago after he tuned them to factory specs, I took it to the local lake and it had a lag or hesitation in the low throttle range, meaning coming from just above idle...

Thanks. I'm new to the carb tuning of skis. What's the pop off?

So I finally got my 90 super jet with 760 engine running good at the local lake with a msl altitude of 1000 ft. Today I went to silverwood lake and it was a disaster. The lakes msl alt is around 3-4000 range. From the moment I set it in the water it would not start. Then the new battery died...

Interesting thanks. Well I hooked up a new battery and it started every time. Now the next problem is after I crash and restart it, it kind of Boggs and lags for a few seconds then it picks up again. But the final lap was after I crashed , it bogged after restarting then picked up. On the same...

Ok I'll keep that in mind. I went out to check, replaced the battery and now it seems to not have spark. There is a black and white wire set that was disconnected when I ran it at the lake, the wires have an in line connecter at the bottom of the hull near the head. I connected them thinking it...

Ok I'll take a look thanks

Hey thanks for your reply. I have not because I'm not sure what the proper way to remove the cover would be. I see 2 nuts on the far left and right sides, and smaller screws surounding the parimeter of the box. I didn't see the point of trying to open the box because if I was to open it, I don't...

It has a 760 wave runner engine and sadly that's all I know. I can see some wires that have been cut and capped. I tested my battery while running and it puts the same voltage as with it shut off. I am trying to post a pic so you can see my issues, thanks.
