Re: Help with Heat Riser spring direction

Cardinal Santana, if it's not too late to add this, as i just noticed your heat riser spring discussion this afternoon, i fiddled with the adjustment on my NOS manifold heat control valve thermostatic spring on my '47 Super, but it works as the gentlemen above describe. If all else fails, a longtime Packardite told me you can take your original to a decent, long-established parts house and find a choke thermostatic spring that's close. You're making me feel guilty because i bought the last one Max Merritt had in the '90s, tho' he's likely unearthed more since.

You didn't ask, but assuming your thin tin manifold heat control thermostatic spring cover is rusty toast after all those years in the tundra, i conned John Kepich into reproducing it in stainless steel, so contact him.

Finally, as i exhausted my play value with that project and didn't want to revisit it for a few centuries, i lubed the shaft with a mixture of kerosene and powdered graphite, but i bow as always to any superior intel from the worthies on this forum.

Prosit.
