We now return you to your regularly scheduled programming

After a too long break for holidays and vacation Im ready to get back to work. One of the things I noticed the first time I inspected the engine were two pipes so rusty they had breached. It turns out these are called heat risers and are meant to use exhaust heat to pre-heat the fuel/air mixture. Since these tubes are compromised they are dumping exhaust gas into the top half of the engine compartment.

A few months ago, on one of the first chilly days I decided to try the heat, and got a cabin full of exhaust fumes. This may be due to the heat riser breach, or rusted heater boxes. Since I can *see* the heat riser problem I decided to tackle that first.

The heat risers are part of the intake manifold and cannot be replaced seperately.

To get to the intake Ill have to remove the air filter, the carburetor, and the generator. I removed the rear hood, becasue it was only a matter of time before I hit my head. And it does make it easier to see

Heres a shot of the engine before I started tinkering

Amazingly the air filter just pulls off, no bolts

Next up: Carb removal
