Fuel pumps have been a common problem in troubleshooting carburetor issues. The most common issue is caused by copies of the Square Style Walbro fuel, a highly regarded pump and used during the height of flathead racing. If using an original Walbro, then there was no issue. Using a copy or clone square style pump is a sub-standard piece that can not pump enough fuel to the carburetor. We highly recommend this pump, especially for modified and open race engines. These will mimic a carburetor tuning or calibration issue.
