I bought a rebuild kit from you almost a Month ago. After rebuilding my Carburetor i can only get the engine to run with the carburetor on full choke. I have tried adjusting the idle set screw, but it does not make a noticeable difference. I watched your video on BBR carbs and followed the instructions carefully. What can i check or do to make it work again?

This is an indication of one of two things.

1 There is too much air, possibly caused by a vacuum leak.

Using a spray carburetor cleaner (be sure you get the straw that connect to the spray nozzle), spray around the throttle body, both where it mounts and where the throttle body connects to the float bowl. If the RPM changes, then you found a vacuum leak.

Check other possible connections for a vacuum leak. The intake manifold is one of these.

If the problem is new since you did the rebuild, then you could probably concentrate on the carburetor.

Most of the kits have multiple throttle body gaskets and it would be easy to install the wrong gasket. This is a common mistake I have made more than once. Carefully inspect to make sure air isn't being allowed to enter the carburetor at that point.

2 There isn't enough fuel.

Recheck the float level.

Make sure the needle isn't sticking closed. Cleaning the viton tip with mineral spirits can help with this.

Poor fuel pump pressure could also be the cause. Test the pressure and compare with what is printed in your engine manual. I don't know what is should be and would have to refer to a manual myself.

Look for any restrictions in the fuel line. Where there is rubber line, replace with high quality fuel injection hose. Ethanol will eat the inside of any rubber line.

Spray carburetor cleaner through all of the passages. One may be clogged.
