Hi,

I am trying to adjust the dual HS4s on my 80 Spitfire. I adjusted the carbs to the recommended starting point to try to get a fresh run at adjusting them.

Turned the jets down 12 flats (2 turns) and then turned the throttle screw down 1 1/2 turns after it just came into contact with the lever. I noticed that the throttle screws were not in contact with the lever when I started.

When I started the car it was running about 2600 rpm. When I got it back down to close to 1,000 rpm, it looks like the throttle screws were no longer touching the levers. Choke seems to be off, the fast idle screws are not touching. I rebuilt the carbs about 4 years ago.

I did not take them off, but it looks like the butterfly is closing well.

Any suggestions on what to look at, before I take the carbs off to inspect the butterfly more closely?

I have adjusted the valves, and timing.

Thanks,
Roger Elliott
