Post question on starting a 350 sbc

Sometimes my 350sbc will act funny when starting. It acts like its not getting enough power from the battery or it's out of time. It doesn't matter if I turn the distributor a little bit either direction, it still does it. Also, I have a brand new battery with plenty of power to turn the engine over. When starting, the engine will either backfire throught the carb or act like it trys to start, but kicks back a little. Sometimes in takes a couple tries to start it and once running, it runs just fine, with plenty of power. It has a fairly new distributor and cap, rotor and all, with new plugs. Any ideas what's causing this? It never did this before and doesn't always do it.

Man , IT sounds like you might have some wiring problems or your distributor is of it can run 180 Degree's of. It will run but it will not be right It will drag when trying to start and run your battery down . Go over your firing order it is 18436572 in front of caror truck right side is 1357 and left is 2468.

Make sure everything is right.

#1 piston at TDC on compression stroke

Line up mark on balancer, should only be off a very little

Stab dist. so rotor is pointing to #1 spark plug wire on dist cap.

Now it should be close enough to run so you can use a timing light.

As 70 nova said make sure the firing order is correct. 18426572 clockwise rotation. #1 wire should be to the left side of the engine at approximately 5:30 position on the dist. cap.

It really sounds like the timing is way off.

My vote goes to a bad starter motor, try bench testing and see what happens.

There's about 20-30 thousand miles on the motor. It usually runs ok, but lately is when it started. Is it possible for it to jump time? If it is a couple teeth off, will it do that? The starter is maybe 4-5 years old. I guess I need to check the starter too.

Im willing to bet your off a tooth on the distributer,Bring your motor to TDC like your going to drop in a new distributer and check the position of the rotor.
