Going to full factory restoration on the General, except for the ignition because I'll never go back to a prestolite setup...
Welded the pipes in, got the manifolds mounted, new gaskets, etc etc...
Installed the teamgrandwagoner heat rise with the gasketed surface to the manifold, the flare's side to the exhaust pipe, the riser weight toward the cabin and the weight to drop when hot...
However, when the engine heats up, it never opens. I even let the engine heat to above normal operating temperature, which it NEVER does at idle and even spit a little coolant because of the temp. Still needed a screw driver to prop it open, in which it snaps closed immediately after letting go.
I'm sure it opens when throttle is opened a little because I believe I can hear it, but the engine heats up well above normal and will probably overheat in traffic with current setup.
I believe the spring is just wound too tight on this unit... But doesn't the increase in heat cause the spring to expand increasing tension... Wouldn't that close the valve tighter?
The total weight to open the valve is well over five pounds... Feels closer to ten pounds pressure with the screw driver prying it open until it snaps back closed.
I've called tgw and they were supposed to get back to me, but no response.
Is anyone familiar with this unit?
Can I simply let the spring free from it's catch for one or a few rotations or until enough pressure to simply hold the unit closed with low pressure?
Is the mechanical setup of this unit even correct?
Did I do something incorrect?!?!
