Carb Help!!!

Turn the initial timing up to ~15* and DO NOT drive it until you find out where your total timing number falls. 9* is not enough initial timing on a 340 unless you are taking it to a smog test.

You should see no fuel dripping in from the boosters at idle. If you do, that's a problem.

Take the carb and baseline it to whatever ede says to set the idle mix screws, etc.

Something is definitely not right if it won't run below 2700.

If the 800 ran OK, put it back on.
