Hello everyone, well I bit the bullet and purchased an M-274 a4 AWS. it was owned by a vietnam vet for over 20 years. Anyway its in decent shape, it has electric start and and an alternator upgrade . It needs seats repaired, some cables, ect.... It has no spark. can anyone give me some guidance on what to look for . It has been sitting for 2 years. I replaced fuel filter, oil, , oil filter ,battery and cleaned the gas tank, any help would be greatly appreciated.
