Flutter sound Question
 
I have had a flutter sound in my motor recently. I did replace the carb to no avail. It has that sound like when you get cheap gas. I did fill up with premium, but it still flutters. I adjusted timing, but still there. I have put octane booster and racing fuel in it and it still flutters. I get the feeling the old truck needs a valve job.

Any ideas?

Thanks.

Can you be more specific on the noise, the word "flutter" is pretty vague.

Details on the truck, and engine would be helpful as well.

If it's really old... it's probably telling you it's time for a rebuild. Could be a cam going flat.
