series v twin stromberg cd150s
In trying to understand one thing more and more questions arise.
while fiddling with my carbs and a spare set, there were a few things that beg explanation.
1) some metering needles had stampings and other did not. I assume this suggests a) standard— no stamping, and b) a different size/thickness than standard That the stamping informs.
while I understand what a thicker and thinner needle will do, how does one determine what is best for ones car?
2) not all air valve pistons that fit into a cd 150 carb body are identical. How many are there and how is one to determine what is best for their car?
My carb issue: I have been experimenting a lot with mixture and slow running adjustment screws. When I get the car running “ great” I get dieseling at shut off— when I control the dieseling at shut off, the car hesitates and pulls away like an old man getting out of a recliner ( 1st hand knowledge) hesitates — stops and starts — until the full compliment of fuel is engaged.
Essentially: rich runs good, but dieseling/ lean runs badly no dieseling.
can some suggest a place to read up on better understanding my carbs that would explain metering needle markings and air valve differences?
How do I achieve —— runs great , no dieseling?
thanks all
