? 'bout backfiring on an inline 6

[seanner]

I'm working on an ''84 amc eagle with an inline 6 cylinder, at trans.

the prob is that it's backfiring through the 2 bbl carb. HELP ME!!!!

okay, I put a carb kit in and it solved most of the back firing. It only back fires when I put the engine under a load (in gear.)

Possibilities: timing chain, old wires, catilatic converter.

Any of you die hard amc buff's know what is causing it?

the car has 90k miles on it.

Thanks for your time!!!! Seanner

Have had this problem before on a 258 I6. Adjust the time and it fixed it in my case. I dont think the cat would cause that nor old wires. Try loosening the distributor and twisting it a little to adjust the timing.

another thing you have to think of is the miles on the engine. it could be the timing chain is getting weak. if adjusting the timing dont work try and check the slack in the chain. if you dont know how to do that let me know ill tell you. good luck.

The previous 2 posts are good suggestions, however, 2 other sources of carb backfires are a excessively lean air fuel mixture (likely fixed with the carb kit) and at least one leaking intake valve. If nothing else fixes it, do a cylinder leak down test to help diagnose the problem.
