318 Engine stumble

It does run better this way. The secondaries are closed down now. They barely touch the bores so as to not bind up. I seared them down all the way and lifted them just barely off the bore.

The primaries were returned to the square pattern and I never had to adjust the fast idle or the transfer slots. They are sitting at the square pattern now.

Mix screws are as you say. They were turned out 1 1/2 turns to base adjust them and turned in until the vacuum signal was highest.


I opened up the metering block and found the carb to be really clean.
All the jest and idle passages were really clean.


Will adjust the points next and check the rubbing block..
This has not been done yet.the rubbing block has never been lubricted that I know of.

The dwell was tested with a swell meter and showed 42 as opposed to the 32 you showed.

Will test drive it soon and see if that stumble is gone.
