Aircraft carb heat is warm air from a shroud surrounding the exhaust pipe and a manual selector valve.
Sound familiar?

Hey Davis911,
I did the exact same thing as you a couple of years ago and it has worked great for me. I don't even take it off in the summer anymore. I can drive my weber in single digits and have no hesitation or stumbling.

Chrysler K 2.2l air filter with preheat for weber progressive

I have been working on this manifold heat box
This is a modification to prevent carb icing on type 4 engines equipped with weber progressive carbs, initially the box conducts heated air from the No. 1 cylinder snorkel, and when the engine gets hot, the box conducts heat from the crankcase, the system turns on and off automatically via the stock 73 temperature switch that grounds its terminal below 12 celsius, and manually with a toggle switch, all this keeps smooth riding at any temperature.
The cork isolations prevents heat dissipation. |

| I read this idea on a Cessna planes forum, the cessnas have an intake preheat switch on dashboard that opens and closes preheat flap, just to prevent carb icing, but preventing also from runing rich , on VW this process is controlled automatically, but then..what if. Im just about to doing it using the T2 1973 vacuum advance cut off solenoid valve in line to the preheat vacuum signal, then the solenoid connected to a possitive and a negative switch to the dashboard, it can also have a neon light to notice that preheat is on. some opinions? by the way T4 1700 with weber progessive and chrysler k air filter (see photo gallery) |
