Carb Help 2000 GP760
I'll try to make this short:
Bought a GP760, ran good the first day. Second run, only half power. Died, wouldn't start again. Got with oside (carb master) he said check carbs.
I checked carbs, clean inside and out. Replaced fuel lines. Replaced fuel filter. Replaced spark plugs. Cleaned oil injection lines.It will not start. When it does with carb cleaner spray, it wont run with oem "airbox" on. It will without it. Once it is shut off, it wont start again, even with choke on, unless it gets a shot of "gas". It acts as if it is not getting fuel, and backfires while trying to start. Oside said check the screen inside the fuel pickup.I dont know about Please anyone who has some idea's, input them here. I need some help!!

Did you rebuild the carbs or just check in carb filter?
The screen in in the fuel tank for the pickup it could be clogged.
Is there a inline filter/water separator on that model?
Another question is.. and it is a silly one.. Do you have the fuel lines on right? Return vs. feed?

Get a can of fuel run a line from the carb inlet into the can try starting the ski if draws fuel from the can and runs you know your issue is upsteam from the carbs, if not it is in your carbs. Remember the inlet is the fitiing closest to the base of the carb.

reeds? bad gaskets on the intake or exhaust side?
Poor a little oil into the plug holes and try compression test again.

Did you find anything out on the 760 yet?
Is the compression bad on the 760 or one of your 1200's?

Try running the reserve line straight to the fuel filter

Ok, I have 75psi on both cylinders. Weird that both are low and exactly the same. I am going to re-test with another guage!
