Heat Riser Repair

[clazar]

Has anyone used the heat riser repair kit ?? Although mine is rusted in the open position, i would like to have a working part. Do the repair kits work & how hard are they to do ??

You need to remove the manifold, remove all the old heat riser parts and bushings. Install new bushings. Size bushings for proper shaft fit. If any stop pins are broken or missing you will need to fabricate and install them. Press the shaft on the the damper weight. Position spring and stop spring on damper. Assemble shaft and flap into manifold. Position damper and flap. Weld flap to shaft and install remaining spring. Put manifold back on. Just takes time to do it right. Not hard to do. The kits work fine.

mine is rusted in the open position

Personally, I'd leave it that way.

When not working choke will not work correctly

A lot of folks block off the heat riser going to the choke, if yours isn’t then go for it if you choose.
I’m going to destroy my autocorrect...

Choke works perfect on my Superbird. I have never touched the carb, not even a mixture screw, in the 32 years I've owned it. My Heat Riser is pegged full open.
