I have just purchased a '73 Auto 12 with the k301s, it came with a silencer which had no baffles.
The engine starts and runs well, from idle to max rpm.
Air cleaner is there, and I've not touched the carb.
So I bought a new silencer ( canister type, exits by the chaff screen )
Having installed it, I ran the engine at around half speed, but the silencer glows bright orange, so I shut the engine down.
Now I know they get hot, but surly not that hot, without even a load. Can anyone
