Pro 785 Wont accelerate first time out ??
Bought a 97 785 Pro over the winter & took it out for the first time this weekend. Supposed to be fresh rebuild by a 785 guru, exhaust pressure tested for leaks & everything looks good/tight on engine & pipes. The ski starts fine and runs slugishly up to about 25-30 at say 1/4 throttle & just bogs at anything over 1/4 throttle. Exhaust valves are not opening at all & tach does not work on MFD (CDI Bad ?). Tried making 1/2 turn adjustments on carbs but did not change anything. I plan on testing valve actuator box & CDI. I realize there are a lot of places to look for problems after searching this site, but thought someone might have had this same problem that can help.
Thanks, Ryan

exhaust valves wont open until at least 4k rpm..... does sound like fuel issues...or possibly compression...
might have to pull carbs and look at em...check internal filters..and check/change fuel lines etc..
i would also check compression
where are you from?

Thanks guys. By fuel switch I assume you mean the on/off switch & does the fuel pickup in the tank have any type of filter or sock that could clog?
Thanks, Ryan
