You can buy a bolt on bracket to fix both those.

And that’s not a double pumper. Likely single feed vac secondary.

Thanks, I was skeptical of it being a dbl but I’m no professional. I appreciate the clarification! Also thanks for the link. That extension will soften up the pedal?

Moving the cable further from the pivot point will give it more leverage to work on opening the throttle and will require less effort at the peddle. Think of it like putting a cheater bar on your ratchet. You have more leverage with the cheater bar because you are further from the pivot point.

Make sure you keep two springs on the return, even of you do need to change them for lighter springs. There are two in case one breaks.

Thank you, that makes sense. I like understanding the “why” something works.
