8N Cuts Our Under Load

I read some previous posts, and most people say to look for a fuel flow restriction. Here is what I have done:

I disconnected the fuel line to the carburetor and let the fuel drain out. It flowed freely, leading me to believe there is no restriction of fuel before the carburetor. There is no fuel filter in the line, and the sediment bowl was pretty clean. There is a filter in the little 'elbow' that screws into the carburetor. This filter had a couple pieces of rust/debris in it, but not enough to block the fuel flow significantly.

Do you have any other ideas of where fuel flow could be restricted, or if certain carburetor conditions could cause this to happen? Any suggestions would be greatly appreciated.

I had some of the same problems. Mine was in the elbow that goes into the carburetor. The way to check is:

Turn the gas off.
Disconnect the fuel line from the elbow.
Remove the elbow from the carburetor.
Re-attach the fuel line to the elbow (now free from the carburetor).
Turn on the gas.
The gas should run freely all the way through the elbow.

This takes as long to type as it does to actually do, but once you have done this, you will have positively confirmed that you have good fuel flow from the tank to the carburetor.

If that doesn't work....then Evil Steve is on the right track.
