69 340 AVS fuel leak

Yes I did, I think it put alot more tension on the choke plate, making for a richer adjustment,and longer partial choke operation. With the spacer installed under the carb, the choke opens up sooner. Does your fast idle cam have any steps on it? Mine does not, and to me that makes it more difficult to set the fast idle.

For example, when I set the fast idle speed high enough to keep a cold motor running immediately after startup, I will let it run for about 30 seconds then tap the gas, the resulting idle speed is too low, and she stalls. I looked and the fast idle speed screw is still on the fast idle cam, but still needs more fast idle to stay running. Increasing the fast idle makes the start up engine speed too high.

I'm going to double check the choke pull off setting.

Anybody have any luck grinding steeper "steps" into the fast idle cam?
