Fj-40 tuning issues

[beaverlj]

I just bought a 1963 fj-40 off of Facebook marketplace. It was not running when I got it and had a new carb on it with no brand. I got the car running and idling well and the timing set to 7 btdc. Whenever I give it gas or when it’s under load it starts sharply popping out of the exhaust. I thought maybe the mechanical advance wasn’t working but after taking the distributor apart I can’t really tell. It does move but doesn’t really spring back like other distributors I’ve seen. I don’t know if I’m on the right track with timing or not.

Post some pictures of your mystery carb. Have you walked through the fsm timing procedure?
