I have been through this personally with a couple of Eddy 750's and I have a solution that Does Work!

1) Verify that your floats are set properly

2) Try different springs for a quicker opening of the needle.

3) Verify that your accelerator/plunger is good(replace if any doubt)

4) Adjust the linkage that operates the accelerator; There's 3 settings, I believe the arm should be in the top hole.

5) Finally, the thing that most guys won't try: Remove the Primary Squirters and drill them out very, very slightly(get some tiny, tiny drill bits). Don't be afraid to try it.

The last one is what did it for me.

Let us know how you make out.
