even compression is as low as 50, it still should start, right?
Yes
Back to basics...compression test 1st,spark plug condition check , firing order, distributor cap,rotor check,spark plug wire check for ohms,check for spark at each plug..not just 1..gas flow and volume..
Agreed, 1000%
Always, ALWAYS start with the basics.
Do you have spark? if so,,,Good, If not, why not ?
Pull the air cleaner and pump the throttle while looking down the carb, See fuel spraying? if so, Good, If not, why not?
But based on your initial post.
My gut says the timing chain jumped
