I have a VJ50TLETB on a 20 foot pontoon. I hadn't taken it out in a few months, but did the other day with a few friends. It fired up fairly easily for having sit for a few months i was actually a bit suprised at that. Upon launching it though I was suprised at the dock when the fast idle lever was all the way up it just didn't sound like it was reving as high as it used to. Predictably when underway with the throttle all that way down she wasn't whinning like usual. I dont have a tach but estimate her top end to be around 2500-3250 RPM. The boat was pretty heavily loaded but it's propped for those conditions. I know it's running on both cyl as its only a two cyl when one fails (and has in the past due to a faulty 'new' powerpack) you can definatly tell and it wont get above a rough half idle, that and there was no sign of unburned fuel so I'm pretty sure all is well ignition wise. I've redone the entire ignition system before, actually just short of a engine rebuild, and carb rebuild I've done everything to the motor that I possibly could have. My question is... Is this lack of get-up-n-go indicative of needing a carb rebuild? I've ordered the carb rebuild kits as I'm guessing that this is what it has to be, but just wanted to see what the old salts have to say. Your opinions please...
