Changed dist runs crappy now

WEll old distributor crapped out so changed it out with new. Like a dummy I didnt mark the old dist so I found tdc by hand cranking and installed dist with 1at tdc. Car started and I played with timing by ear. Sounded as good as always. Took it for a drive and and it feels like I'm driving with the ebrake on. Doesn't wanna go. I did notice at full throttle I get a backfire. How could my timing be off if I found tdc and it started right up? Any fixes for my problem. Thanks

Your timing is likely off a tooth or two.
When the #1 piston is at TDC, the rotor inside the distributor needs to be pointed directly at #1 plug wire terminal on the distributor cap.
Make sure you are at TDC on the compression stroke.
Otherwise you could be 180 degrees off.


Once you are sure you have it installed correctly, then time the engine with a timing light.
Don't forget to remove the spout connector when you are setting the timing.
If you don't, it will not work properly.

I've tried it a few times so may just be tired. I'm probably just gonna take off the valve cover tomorrow. So I turned over the engine and felt compression at the 1 plug hole and put rotor at 1 when compression was highest. Shouldn't this be right

Have u tried taking the number one plug out, put a screwdriver in(helps if u have a friend) and turn it over by hand until u feel the piston push the screwdriver as far as it will go up before dropping back down then set the dist?

Yup used an old clean pushrod and it seemed like the piston was at the top of its travel and set the distributor and still feels sluggish and getting backfiring.

Like I said, you have to make sure you are coming up on the compression stroke.
Otherwise, your timing will be off.
