VCCA Home Forums TECHNICAL - 1945 AND NEWER 1949-1954 Bi-metal Thermostatic spring for Exhaust flap

The Bi-metal Thermostatic spring for Exhaust flap that regulates the carburetor heating...can new replacements be found for these? In this case a '49 passenger car. Or is this a junkyard/swap meet item? Mine broke where it fits in the slot. I may be able to make it work, but it will be about 3/8 inch shorter than original.
Thanks!

"The Filling station", Chevs of the 40s are two places that you can purchase them. Be sure and folow the installation instructions in the manual!

Thanks, I'll try them. I've failed to find it in their catalogs, and it seemed when I inquired years ago they responded in the negative, but I'll call them tomorrow and check it out. I just read the procedure last night in bed, and I see that it doesn't really heat the carb, but in truth warms the intake manifold. At least my flap isn't stuck, it flops around like a weathervane! :)

dopey...that should be an fs-141 exhaust manifold heat control spring...fits '37-65...

I'm looking at a picture of it now on the FS catalog site..Thanks! Don't know why I couldn't find it myself.

Hey Richard..... now just kidding; BUT - it was YOU who picked a name for you on this chat place, wasn't it?? Like Skippy says, "I'm so funny it just kills me." Incidentally is that the 'part' I emailed you about??? Bill.

Yeah Bill, I should have checked to see if Sleepy, Sneezy etc. were taken

Hey Buddy: You're smarter than most guys based on how you 'run' the CRR web site. Keep up the great work!!!

Incidentally, glad you found what you needed. Bill

Them heat riser valves are nothin' but trouble .... even when you can get them to work.
I always secure my riser valves in the open position

MT, what is a riser valve, anyway! Don't hardly even need a choke in Texas! just lots of 50-50 coolant! and $2.059 gasoline.

When it is 40 below the heat risers are a good thing!

Heat risers are not needed in the rust free desert of Arizona where we never get below 25 degrees [ even during the worst of winters ].

Even if I had to deal with 40 below temperatures I still would not trust that crappy bi-metallic spring on the heat riser & I would still secure it in the open position.

If you are dealin' with sub zero temps. you are better off pluggin' the thing into a block heater if it is gonna be that cold.

When it is 40 below I will be down South! I really haven't seen the effect of the heat risers.Most of the local four cylinder cars(except for the VCCA cars) don't have the heat boxes on the exhaust. I am sure they help to curtail carb iceing as well as help atomize the fuel in harsh atmosphere conditions, such as North of the Mason-Dixon line and at an altitude above 8,000 feet. Heck, I had not even had the heater on for 4 years in the '53 until we were in Pittsburg KS. last month. BTW it worked really well. We have icepacks to put on the fuel pumps to prevent vapor lock! What I need is a good factory 6 volt A/C for my cars, but since they didn't build a 53 chevy in Arlington those builders up North decided that an A/C was not needed.
