Hegnrist sounds like you have an issue with the linkage so worth checking that out. On my twin 45's i had basically backfiring through the bell mouths as the carbs were not properly balanced and jetted correctly. I did reset the idle screws back to the stops and then adjusted from there but the balancing i could not do due to not having the correct tools. (it was difficult then as i was in Germany with the RAF at the time)
However once it was on the rolling road back in the UK and two hours later they ran sweetly and i had a cheeky 124 bhp at the rear wheels.
the linkage is all new, i had a word with the guy who does the r.r's on my cars and he is said its due to over fuelling so i need to have a fuel pressure regulator, the jets as its not been jetter yet and the floats possibly. so all i well i think
124hp? wow! niiiice
last time i got 75 so if its any more i can tell who ever was telling swan necks were bad to stick it hehe
as vizard said there is nothing particularly wrong with them, its just better have one with more length :)
thankyou sonikk4
