Run a piece of weed wacker line up the hose to try to clear any obstructions. Mud daubers love to crawl up them and clogged them up. |

90 Degree looper 120/140's are 'weak' out of the tell-tale due to the automatic draining pump system out of the cowling. Works like an ejector pump.
Take out clean and check Your thermostats (vernaterm) and membranes that they are working properly. The pin in the vernaterm has a tendency to be stuck open.
Start the engine and check temp on both cylinder banks. At idle, even temp, barely to touch when putting hands on top of each cyl bank. |
