Default 87 LT230E quadrunner erratic run issue

I've been piecing this bike together since summer. A few days after I bought it(rough shape) it showed signs of life. Basically used a choke plunger from another suzuki and tinkered. Over the past few months I got numerous parts for it, and its too the point it seems worse. Only recent changes have been choke cable, throttle cable, intake tube, header pipe, and used coil but tested with good spark on universal spark tester. The old one was arcing to everything in arcing distance through plug wire.

Now it starts with choke, runs a few seconds, then idles down and stalls. trying to throttle it results in stalling. Seriously no more than 10 seconds after initial start, then it gets worse every other time. Its like the rebuild kit for the carb made no difference, if any worse. I've replaced head, head gasket, rebuilt carb, D7EA plug .024-.030". Ngk plugs are hotter plug lower the number correct? Calls for D8EA.

After head, and gasket, bike got better compression and seem to idle smoother. One thing I realized when doing the head gasket was slack in the timing chain. Didn't check timing marks though. Keep the original cam timing. But once I rebuilt the carb, it seems not to idle as long as it used to, that might be due to the choke cable or plunger though(cable and plunger from 92 lt250 4x4).

If anybody has any advice or troubleshooting advice, it would be appreciated dearly. thanx

I am to the point of having a bon fire with the quadrunner as the bonfire center.
