GP 760 Starting Troubles
When I take my 760 out it runs good. I use starting fluid to get it started and the problem I have is if I stop to take a break for 30-60 min it doesn't want to start and takes a few tries of starting fluid to get it going. Also I clean the hull out before getting to the water and by the end of the day it looks like the picture. I'm new to 2 strokes and pwc but have many years of 4 stroke also if anyone can help identify the carbs.
Please offer some suggestions on where to start. The carbs looks freshly rebuilt but I don't know when they were as the pwc was given to me. It has 150 hours on it.

Not sure about the residue in the hull, but do you have the primer kit or still using choke? Primer kit is the way to go for the starting issue I'd imagine.

Primer kit is awesome! Installs in under 20-30 min, and all you need is like 3-5 pumps, and she should fire up. Also, on a 760, I'd convert to pre-mix. The oil pumps suck. Both my 98 and my friend's 99 pumps died and I caught mine in time, he did not. His cost him a trip to SBT and $1200 for new motor. We have both since traded up to newer skis though. He has 2012 VX Deluxe, and I have my gremlin infested 04 GP1300R. lol
But yeah, the primer kit is well worth it!

Sounds good, any idea on why it would run for a hour or so and once we take a break it doesnt want to start?

Could be carb issue. When were they rebuilt last? Hours on motor and carbs? Check water separator? Fuel filter?

get those damn air filters off ! You could be leaning out the motor with too much air, unless it has been rejetted.
Second thing to do: take the carbs off and rebuild/clean them.

Ok now I did a compression test, Front at 30psi rear 110psi. Should I get a top end kit and rebuild it or suggestions.,

Ouch. Hole in front piston it sounds like. Rebuilding is dicey. By the time you get new cylinders pressed in, head machined, new pistons, rings, bearings, etc...you're up close to $750-900. SBT offers a core swap for like $1100ish I believe. You get what you send in as core. And it's ready to install.
Your motor is dead. Sorry to say.
