I own a 1949 Special Deluxe, said to have been bought by a nun in California! Being a P15 I guess she got a good deal on a 1948 model left on the lot.
Imported to the UK in 2015 in fantastic ‘survivor’ condition, and carefully brought up to running order by the guy I bought it off. He was meticulous, but I think he had the mechanical work done by others, and I’ve found one or two minor things make me think they weren’t maybe always the best.
When I got it, the ignition was way retarded and it smelt really rich. Timing soon sorted but I’m puzzled by the carb. The idle mixture screw was way too far out so I connected a vacuum gauge and tightened it in, but to my surprise the engine still ran when hard tight. I took it out suspecting something lodged in the needle or seat, but seems clean. However it still runs fine, and smells less rich of course, when fully tightened home.
Am I missing something? How’s the engine getting any gas if the idle jet is fully closed?? Book says half to one and a half turns out.
I’m not familiar with this carb, but it seems pretty straightforward, and this one is new or rebuilt, fitted by previous owners.
Grateful if anyone can tell me what I’m missing here!
