I have a 1974 MG Midget that I bought last fall. I noticed that if I fully depress the gas pedal, the primary arm never extends enough to engage the secondary barrel. Does anyone have any pictures or advice?

Does it look like I'm missing any pieces on the throttle linkage?

Any advice would be greatly appreciated.

Looks like you are running out of throttle travel before the secondary opens. Disconnect all the cables and see if it opens manually. (Guessing it does) Those are pretty sturdy. Work on getting better cable hook-ups. smileys with beer

It's opening some but not all the way. Gotta make sure the pedal is coming all the way up when you hook the cable up.

Like Joe said; you need to get a better cable mount.

Robert. You can see that the cable pulls the linkage to Horizontal, about 9:O'clock, it needs to go past horizontal, about 8:O’clock try moving the cable “Trunion”, one hole back, Cheers smileys with beer

I adjusted the cable linkage so that it pulls the throttle down more and it is better, but it still isn't fully opening. How would you suggest I get more peddle throw? Just bend the peddle rod the lengthen it?

Nevermind, I got it.

I do think that the carb needs rebuilt, but that is a project for another day
