[jpetty]

Hello everybody,

Re: no power at take off. HELP!!

have you check compression and spark with a spark tester? did you remove the jets when you did the carbs? have you done a link n sinc?

Check the plugs most likely one will be wet and possibly fouled.
Get a spark checker.Check for a good strong spark.

If you got good compression and spark on all 4, look for debris/water in your fuel tank. Make sure the tank vent is open and clear. Was ethanol-blended gasoline recently introduced in your area?

Check your carb throttle valves, make sure they're still parallel, and opening fully when you go to WOT. And make sure the timer base is moving all the way to its stop when you throttle up.

i did have one plug that was wet. if looking at the back of the engine it was the top left.
i had the compression checked and it was fair. check spark; all good, but did it on the trailor, not under load, will that make a difference
