Hi All
I have a Tecumseh motor on an outboard leg that needs a carby
I need to identify the motor first of course . It has a small tag with the following on it as the only ID i can find .
T-643-12 and another number which is 6074116.
This motor seems to have been put on what i think is an Asko leg and the only other ID i can find seems to be the name seamaster. I have been told that the motor is from a lawnmower lineage and was assembled on the outboard leg in Australia ??
Can anyone assist
