Sometimes you hate them...

Sounds like a carb problem. But if you suspect the timing chain has jumped, you can check it without removing the timing cover.

1st. Ignition timing will be way off. Ignition timing runs off the cam.

2nd. If ignition timing is off, pull the valve cover for #1 cylinder. Put the dampner on TDC. If the cylinder is on the compression stroke rotate 360* so your on TDC exhaust stroke or pull the other valve cover off for the #6 cylinder (1 8436 572) Now, while observing the rockers, move the crank about 20* for and aft of TDC. You should see both rockers for that cylinder move. If the chain has jumped even 1 tooth, only 1 rocker will move.

But it sounds like a flooded carb.
