Power Problem

[genesis08]

Thanks Spare parts,I have installed a brand New carb,sent over from florida.Unfortunately I cannot get a replacement electric fuel pump here with 1/4 bore barbs on it.The original one I have is bust!With regards to tuning the engine is perfect,timing etc.Starts on the button,
What is your thinking on the fact that she revs up with no problems but once the load comes on its a disaster?

Regards Brian

Ps I presume pertronix is elecrtronic ignition system,where can I get one?

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!

Regards Brian..

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...
