Every fuel distributor can be slightly different and the fuel mixture needs to be adjusted after replacing one. This is accomplished by adjusting the 3mm allen inside the "tower" next to the fuel dist.

Replacing the fuel dist with one from the single cam engine isn't advisable. It may run but the twin cam part is designed to flow more fuel. This may be the root of the bogging problem.

Recommend to take the old fuel dist and try to replace the plunger seal. Not much to lose and everything to gain.
