Today I adjusted the accelerator pump cam to #2 position. This latest 1850 carb has some slight differences compared to the one I bought in 2002.
Hmm, honestly can't tell the difference between pump cam position 1 and 2, so for the moment I will leave it at #2.
When I step on the throttle and it drops down into 2nd, there is a momentary bog(VERY slight) and then acceleration happens much quicker...
I need to check to see if the vacuume secondaries are actually working. I will try the paperclip trick either today or tomorrow.
Currently the secondary spring is now the stock "plain" spring.
