Found my dads original 1971 duster!

Hey. Thanks! I had a friend check the timing and it’s 4 degrees and 27 degrees. Does that make sense? I know zero about what timing is. Thanks Also, I finally found hose that goes from canister on rocker cover to the breather. Since installing it, it’s really hard to start once it’s warmed up (like if I stop for gas then go to re start). Not sure if the hose could affect anything, or it’s just coincidence
That could be your whole entire problem! You need to pull that timing up to around 16-18 idle timing instead of 4. 4 is ridiculous.
