FWIW I just discovered this issue with my car and im only running a single Walbro at the moment. I tried using the stock resistor with a Walbro and the car would not idle. The resistor is too much for the Walbro and reduces flow to an unusable level.
If the stock resistor was too much for the Walbro, i would say it might be too much for the 044 also.
