I am having a struggle with a (single) 1.4 Bagheera carb fitted onto my new Wade Supercharger. I cannot get the engine to run below 2,000 r/m and the choke is 50% on at that time.
Reduce the choke below 50% and the engine slows down and dies. I have opened the idle jet adjusting screw to the point where it is almost falling out and it did allow the engine to slow down from the 3,000r/m speed which was the slowest I could get it to run when I started.
Over the month since it last ran I have improved the gaskets to the point where I can be reasonably confident that there are no inward air leaks. The manifold gauge is showing about 50% vacuum at 2,000 r/m.
Could somebody tell me the jets used by the 1.6 Murena engine please? Maybe I need bigger main jets??
Thanks.. Andy
A look at my 1.6 shows that it is idle 42 correction 175, main 150 and emulsion tube F46. This seems to work very well. It is slightly at odds with the Haynes Book of Lies though. HBoL says that for the Alpine 'S' engine, it is idle 40-45 main 145
+5 correction 165
+15 and emulsion F54. Hope this helps.
