Hello everyone, now I will start with the engine introduction. I am entirely new to carbureted engines per say, but I'm mechanically inclined. (Only 23) no one taught me so I'm learning.
So, the engine is a 67 year 300-2 barrel that I found from the block casting numbers.
I bought it from a guy who bought a truck that had this engine in it and i got it for 200 bucks because I really needed a buick to fit into my Jeep. And he said it started so I jumped on it.
The engine has had "work" done to it but as far as looks it has the oiling plate upgrade which leaks a bit, and I cant tell but the timing cover may have been replaced a long time ago because it didn't have a timing pointer so i bought one that bolted to it to replace the hangar wire that was in its place, AND Finally it has an ac delco HEI distributor.
I rebuilt the rochester carburetor (2g), replaced the ignitor, plugs, and the dist. harness because it didn't start when I got it, so now it does start and it will run but its not quite right, sometimes when I blip the throttle it'll kind of fall on its face like and it wont raise rpm nust make a woosh noise and almost die, it will gradually if I ease the throttle into it and sometimes it pops which leads me to believe its a timing issue. Before i rebuilt the carb it did the same thing.
I found that timing should be 2-1/2 degrees BTDC with the vacuum advance disconnected and plugged. Needs to be set at 500-550 rpm idle (my innova reads rpm), and in drive with a chock and parking brake set.
But what I don't know is which timing mark on the balancer, I found the online manual on this site and talks about a factory yellow line on the balancer, but thats gone all I see are two groves one with a 0 beside it and one with an 8 beside it. Definitely factory looking, but thats where I'm at now.
Thank you for reading, I hope somebody can help me with this!
