Did you check your timing when you put your distributor back on? I swear to god if you advanced it all the way and end up blowing your motor, you will learn a lesson......

And by timing I mean your distributor angle. If you loosen the 3 bolts holding it, you can either tilt it forward or backwards.... You need to make sure its at the right spot.

 

^ You mean ignition timing?

OP will need a timing gun to set that. Look it up on youtube for a DIY!

 

Of course I mean ignition timing, confusion?

 

Then make it clear when explaining it to someone else.
