Ok,
We're dealing with a 2000XP 951 here.
I have replaced the grey fuel lines with brand new automotive fuel hose. I have totally rebuilt both carbs with kits from SBT including the in-carb filters, all o-rings, diaphrams, etc., cleaned the fuel selector switch, and the spin on fuel filter. I also replaced a busted exhaust hose. Plugs seem OK and compression is good. Drained the fuel tank and refilled with fresh 93 octane.
The boat runs like crap. Its VERY difficult to start in the water and almost any touch of the throttle will cause it to stall. In the rare event that you can get it past idle, it will never come close to planing off and maxes out around 2900RPM. There are occasional backfires (through the carb I can only assume) and some of them are severe.
I know this model has reed valves instead of a rotary valve, so I cannot see a possible timing issue.
The whole purpose of replacing all the fuel lines and rebuilding the carbs was to correct these exact symptoms, yet there is absolutely no difference in performance since the job was completed.
Diagnosing this problem seems to be exceeding my mechaincal abilities, so any help from the experts would be great!
Thanks,
Ryan
