Re: How does heat get to thermostatic choke?

The tube from carb is inserted a very slight distance in the tube which is fixed to manifold. That rusted out tube just heated the fresh air coming in from the bottom which was then passed into the tube going to carb. No actual exhaust gasses were admitted to choke housing.

If you cannot replace the rusted out tube with another piece of steel tubing easily then I believe doing as you propose -- running the carb tube completely thru the manifold -- would serve the same purpose but it could be problematic for future work or removal. Unless there is enough of the old tube left and it is a large enough diameter the complete length to pass the carb tube all the way thru then the elongated tube would have to be sealed in some way so there is not an exhaust leak at the manifold.
