hi, I just got i think an '83 FA50. it appears to be all ready to start. but i gassed it up.. and tried to start it today and it would not go. i did try a plug that was technically not the right one (i ordered the right one).. but when pulled out it was completely dry. so does anyone know starting procedure.. there are a lot of tubes going in and out of the carb. i think the battery might have been dead.. i am charging it. tips would be greatly appreciated .. i could not find a manual online.
