Solex carburettor spewing fuel - help!

GHP2

New Member
Hello Members,
I'm a total Rover novice because I've received a beautifully restored 1946 P2 (or P3??) as an estate settlement.
The vehicle had a complete resto through the mid 2000s but due to the owner's ill health soon after the restoration was completed the vehicle was hardy driven.
As seen in the image, fuel spews from what I can only deduce as a relief valve on top of the float chamber. My internet research on the model of Solex finds no reference of any images or diagrams that shows this valve. The carburettor has the markings "30" and PAA followed by "1-2". I'm fairly sure that when my father-in-law performed the restoration he would have kept the original mechanicals due to the car having enormous sentimental value having owned the vehicle since the mid 1950s.
If anyone can help with advise on the cause of this issue I'd be hugely appreciative. Is it a faulty relief valve or does the build up of pressure point to a different issue internally of the carburettor?
Thanks,
Grant
 
GHP2 i had a similar problem with my P3 and blamed the float level, so adjusted it several times with out success. then i had a serious inspection and close up with a light and a magnifying glass and found a very fine crack in the top where the fuel line screws in obviously the pipe had been over tightened at some time. i repaired it with a two pack liquid mix, no more trouble. best regards Derrick.Smith.
 
I would think the float is jammed or the float valve stuck/ leaking . There isn't a relief valve , I think its just a vent at the top . I notice you are in Australia and this firm had some parts . Search - 30PAAI-2 . I just googled it and have no knowledge of the firm , but there are a number of owners of early Rovers in Australia.
