Power Problem

[spareparts]

from what you've told me, it sounds like the carb, personaly I don't trust rebuilt carbs from shops that can't introduce me to guy rebuilding them( I do my own). One more thing to check, see if the distributor is advancing, put the timing light on it and rev it up, it shoudl advance at least 10-15 degrees or so. Pull the cap off and turn the rotor, it should turn one direction and spring back, if not, its aperfect time to pull the point plate to inspect teh advance springs(and replace it with a pertronix). try ebasicpower.com for the coversion kit, shoot me an email if you have any questions about it... One other thing, pull the fuel filter and make sure someone didn't put it in backwards, the open end should face teh nut.

I am inclined to say that it's possible that the throttle linkeage is out of adjustment..You may have the hammer down but the cable isn't opening up the carb because of too much slack. You are using a different cable drive when she's outta' gear which could be why it will rev outta' gear.
Another thought... If you are getting the rpms but she just won't come up, maybe you've spun the hub on the prop?

Another thought...25 miles of monofilament line wrapped up in the hub?

Well Thanks guys.I will have a look at your sugestions at the weekend and take it from there.There is maybe 1 or 2 more trips left this season anyway but I would like to get it sorted before I haul it out for the winter!

Just when did you start having this problem?
Did something change?
Did you change something on the motor?
All of these are cluses that may indicate adirection of analysis.
As spareparts said, those symptoms tend to indicate a problem with the carbs...

genesis, did you figure out what was ailin' your motor?

If you still have the probelm, go back to basics, check compresion, check timing, check the point gap and dwell(I'd replace the points with an electronic conversion), check to insure the distributor is advancing(rev the engine up with the timing light on the mark, it should advance up at least 10 degrees by 3000 rpm). Check teh caarb to make sure the accelerator pump is doings its job(with teh engine off,have someone advance the throttle back and forth while looking down the carb, it shoudl squirt some gas out of the small hole at the base of the boosters, it shoudl be a fine spray, not a dribble). The only other thing I can think of is to disconnect the shift assist switch on teh shift plate, it may be shorting out eth engine when you advance the throttle while in gear, just remeber to hook it back up, it may make it difficult to shift without it. If you need more info on this, let me know. I still think its the carb
