Hello Guys,
My PA18-95 restoration is nearing the goal.
I have an overhauled C90-12f for which the Stromberg carb has been replaced with a newly overhauled Marvel Schebler MA 3SPA.
The primer pump nozzle for the Stromberg was placed on the intake manifold near the carb flange.
My mechanic claims that for the MA 3SPA is no use to put the nozzle in the intake manifold as this carb has an acceleration pump. He says we need two nozzles, one each for cylinder 1 and 3, for which there is a threaded attachment on the cylinder head (between valve cover and upper spark plug, now plugged).
I have searched for this primer layut, but found nothing.
Help please!
Thanks, Gian
