The consensus from the forum is that you must have the engine tins with the flaps installed and in the open position. It is also preferable to have the thermostat installed and working to get the engine up to temp. Does the thermostat work when the lower tins (air guides) are missing?
My thermostat works on the stove but doesn't seem to get hot enough to open when the engine is running.
How many of you have these lower tins installed?
Where can I get a set of these?
Thanks
Mike
