Hi Wood Gassers,
My newest sacrificial 4kW generator arrived today. It is one of these:
It looks like a well made little machine, especially for the money. I put it together and then started stripping off the parts I am changing. It lost the heat shields, muffler, air box, and gas tank. I am installing a small general purpose fuel tank instead of the five gallon model that came with it. I only want enough petrol onboard to start the engine, purge the carburetor, and warm up the O2 sensor. Hopefully I can put a 1/4 cup in the tank and have it all feed to the carburetor.
The first issue I ran into was the tank mounts. This engine does not have the standard GX200 tank support arms over the on/off switch. It has two little low profile threaded bosses so they don’t hit the large tank. I will just have to burn a bracket. It’s annoying but not the worst thing in the world. The other side of the tank seems standard. I looked at my other generators and changing the block for generator use seems to be a common thing.
The custom threaded exhaust manifold I have been working on installed perfectly. The exhaust was GX200 standard and the exit pipe ran perfectly parallel to the generator housing. I don’t see any problem installing the exhaust heat exchanger.
Once I get all the changes made I am going to baseline the running temperatures on gasoline and then switch over to wood.
Onward and upward.
