Old info for some but I am having an issue with the Solex carb.
Details: Bought this Bayliner Capri (86) to clean up, our first boat.
Inboard Volvo engine.
Penta aq131A model with Solex carb, identified as "old" style
the boat started but idles roughly so we purchased and replaced:
Ignition wires, cap, rotor, plugs.
Cleaned carb and used new kit.
Cleaned up wiring at the coil.
Replaced all gaskets for the rad/exchanger, sea water O rings, etc.
Adjusted the screws out 2 turns as indicated.
When we start it, starts fine but revs around 2000-2500 rpm and we do get spray out of the top but it just will not idle if I try to turn down the idle screw.
This is cold or warm.
I see 4 points of adjustment, the 2 usual ones (idle and the mix screw, both at 2 turns out from soft seat), the pump arm and the throttle shaft.
I'm not sure, and can't find any info on setting those.
I say this because the position of the pump arm adjustment screw may or may not be an issue or it may. There is an indent on the threaded shaft showing where the nut was set but that may be a bit off.
the throttle shaft is bolted to the frame so no adjustment there except for the top, but, I don't know if I should turn the idle screw out 2 turns then adjust the shaft and attach it as having it high or low may affect the idle?
Not certain this makes sense so your patience is appreciated.
Thanks.
