Running Ruff Low Power

[boboh1]

Stock 383 and automatic transmission in my 1969 Bee. Starts fine and drives ok for a few hundred feet then runs a bit ruff with lower power even when giving it more gas. Possible carburetor out of adjustment?

Make sure the choke is opening properly.

 

[boboh1]

I’ll check that. Thanks Don.

Choke sounds likely, or a whole bunch of trash in your fuel filter

Fuel pressure? What pump are you using? Float levels correct, step up pistons working properly?

 

[boboh1]

I am using a brand new stock type of fuel pump. I also had the stock carburetor restored so I assume those two items are working properly. I may need the carb to be dialed in better though.

Stock carb restored. I hope you didn't just bolt it on.

Did it start running ruff after you installed the fuel pump?

 

[boboh1]

The restoration shop tested it on a running engine at their shop before they shipped it so I did just bolt it on. Never drove the car before I received it as it needed work. So can’t really say how it ran prior except driving it off the trailer and down the end of the street into the garage.

Every engine is a bit different so you will still need to set the idle mixture screws and idle speed on your car.
Check that your vacuum ports are all connected properly or plugged if unused.
Double check that your mounting stud nuts are secure (they don't have to be real tight a nut driver is usually sufficient).
