You say you are getting spark at TDC but are you on a compression stroke?
Pull # 1 plug tun over and test for spark, you should hear the compression escape as the plug fires. If you don't you are out on your distributor timing. Do it a few times to make sure. Vince

Yah, kind of sounds like the dist is 180 out. Did you do a compression test? 3 things needed to start, fuel, compression and ignition. If it's ok, set #1 to TDC and make sure your dist is static timed properly.

no i have not done a compession test do have a tester but yes i am on tdc check by pulling #1 and check i have two marks on my balancer in i set the valve to the wrong mark would that make a differnce because when i re set the to day i finger after when i had some to put a coat hanger in the hole that i had set them to the wrong make ii put the timming light on it and it was fireing on the right time

Your last post is a bit confusing, from what i think you are saying you are on TDC when it fires. But are you on a compression stroke or an exhaust stroke? Vince

I'd say dist. is out and/or you have the plug wires crossed.Set #1 at TDC the check the dist to make sure the rotor is pointing at #1 on the cap.

as far as i know i am on compression stoke had the vavle cover off and watch the valve and both valve are closed the dist is pointing at the number one

A compression test will tell you if you have the valve lash to tight. Pull all the plugs and do it, remember to open the throttle to wide open. I would expect them to be in the 150 range. Post your findings.

Hey all just thought i would give an update on my pos it is now running i had a mechnic over yesturday and the problem with it was the valve were set wrongand the knock sensor was not pluged in the other thing is he set the timming at tdc is that what i want my timming at from what i can remeber the like a diffent timming if so what do i want it set at the reason i am asking is because it is a little hard to start and when i put it in to gear it want to die
