Need some help. Just bought this truck. Figuring out all the bugs right now. Long 1st post. Sorry.

350

4 or 5 days ago i was misfiring through the passenger side exhaust. Pulled the plugs. Heavily carbon deposited and some oil too.

Kinda makes no sense.... fast fwd to today... truck was misfiring like crazy from both exhaust pipes. Skipping on the HWY, no power. Pulled into Pep Boys... pulled the plugs... all dry fouled. I mean i guess they were dry fouled. The truck was running like shhht. Threw them away at the store. Should have kept them for pics. Anyways... smelled fuel as i was pulling in too. Truck was flooding. Yes i have a new carburetor and more so, yes i adjusted it 4 or 5 days ago. But it hadn't been running rich for 5 days. I just smelled fuel as the truck was struggling to keep running on fouled plugs.

swapped out the plugs... was thinking also maybe the timing was off. Even though it seems to be running smooth when it's got new plugs... well... no mark on the harmonic balancer.... couldn't time it.... yes i could have by ear... but i need this thing exactly right.

So... could the timing be off? It's got a brand new timing chain and the shop I had it in a few weeks ago pulled the motor, compression was good... replaced the rod bearings, timing g chain, sealed the motor all up.

so there's no reason for me to believe the timing is that bad. Though it might be.

I also think I'm hearing some plug knock... detonating maybe... it's actually was whining like a supercharger after I brought it home tonight. It's running hmmm.... pretty good most of the time... but then goes south quik.

I will answer any more questions you might have getting into this. Need some major help.
