I have this air cooled engine which needs service- won't start. Of course I did not follow the old rule: If it ain't broke don't fix it! Operates a cordwood saw, cut up about 1/2 cord then blew all the dust, dirt, grease, and sawdust out of it, changed the oil, cleaned the oil type air cleaner and sprayed the carb. exterior and linkages with gumout. Well now it won't start. Seems to be getting gas. Can't get a plug out- too narrow for my plug socket to fit into. I am looking to get my hands on any manuals for this engine. A search of antique engine website as well as Wisconsin one came up with model AP4 but said engine info N/A. Any help finding manuals wood be awesome! Love this site!
