Ok I just added headers, and redid the valvelash (turn push rod till resistance + 1/2 turn, flat tappet hydro cam) put in new plugs/wires and now it wont start. Set up thats in the sig.

I checked the plugs, and they were wet, so I double checked the fireing order 4 times, took the cap off, put it to TDC compression stroke on #1, put it too the floor, and cranked it again, and it spuddered out the exhaust, and shot a tower of fire out of the carb at the same time. If I leave it on the floor, and crank, stop, crank, it wont do the fire thing. I hooked up the timing light and while cranking set the base timing to 0, then 6, then 12, same results. I changed plugs again, and they are staying dry so long as I have it on the floor while cranking. The choke is also tied open.

What should I do next? I did try a little bit of starting fluid, but it didnt seem to notice at all. The car ran before it went down 2 weeks ago for headers. I also checked to make sure the balancer hadent sliped, and its just fine.

 

I am not so sure that the headers are as much of your problem.... I think it lies in your valve adjustment maybe. Couple of questions for you..... Did you have the engine running when adjusting the valves? if not then just setting each pushrod 1/2 turn is not going to have them properly adjusted unless you brought each set of valves up and closed all of the way. They acually have a certain sequence for adjusting them all. I forget it maybe I can dig around and find it. I would check the valves out and then double check your ignition timing. Hope you find out whats wrong soon!

 

Oh and the ignition is a full MSD HEI set up.

I did it by the book, or the one that I have anyways. Witch was bring it to TDC and adjust what ever ones where at rest. I also re did it and did the open/closing method, where you adjust one, as the other is closing. If I could get it start, I would gladdly take the oil spray to properly set them.

 

sounds like your valve lash is too tight..

 

I checked compression on 3 of the cylenders while I was chaning plugs, and they all came out to 118-125. Guess I could go out there and check them again. Before the headers where on, and the car ran great, I checked it on 2 of them and had the same results.

 

try backing them all off 1/4th of a turn at a time then try to start it.. than readjust.

 

Well I backed them off and it didnt seem to change. They are backed off pretty far now, I can jiggle the pushrod up and down.

I closed the choke and tried it a couple more times, and it back fires pretty constantly out the exhaust. Enough that It cought some paper towls on fire that were soaking up some oil. I just changed the oil as well, as it was thiner than I liked and reeked of gas.

Im going to start all over again on the valve lash, set it to zero lash, and crank, then start going in 1/8th at a time.

 

i'm leaning towards your wires are 180 out or in the wrong direction, (clockwise/counterclockwise) remember #1 tdc will have the rotor pointing towards the front of the car and crank the car with the rotor cap off to see which direction the rotor turns.

 

U guessed it


Just fliped it around and it fired right up.

HOLLY wow what a smoke show!! These headers are going nuts with smoke right now

 

I was wondering while reading this when someone was going to say 180 off.

That will make a fireball everytime.

 

Congrats on getting it. The headers will smoke alot till all of the paint burns off.
