29tons Posted January 16, 2018 Share Posted January 16, 2018 The motor seems to start very easy even at 10 degrees out .It dose not shimmy or shake at idle I moved the car a short distance and was waking around the back of the car and the 1 tail pipe did not sound quite right I held my hand over the pipe I could feel air pushing out but also felt some air sucking in could someone have the valves to tight? Does The dual exhaust have a crossover pipe? its in storage and I cannot check it out like I would like to. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 16, 2018 Share Posted January 16, 2018 A piece of paper or dollar bill makes a sensitive instrument to check this. If it gets sucked against the tailpipe it is a sign that you have a burned exhaust valve or maybe just sticking. You could try giving it a shot of upper cylinder lube like Marvel Mystery Oil down the carburetor while running, then shut it off. Or when you get it out in the spring put some in the oil, some in the gas, and go for a long drive. Link to comment Share on other sites More sharing options...

JACK M Posted January 19, 2018 Share Posted January 19, 2018 Pretty much every car I have ever owned would fail that dollar bill test. I am thinking valves as well. Link to comment Share on other sites More sharing options...
