My family has had this old beast for almost 20 years, and we put in some work as kids wrecking it plenty. Sat at my parents house for probably 6 years unused and my parents gave it to my husband and I because we have a farm. Well weve troubleshooted getting this thing running for quite some time now. New gas, new spark plugs, new battery, new fuel filter, cleaned the carburetor, but she still wont start. I have a tube leading from what I think is the carburetor (our buddy helped clean it and I was not around for the job)that goes nowhere, but has fuel that will pump through when key is on. It turns over, but wont catch. My manual doesnt have a picture or description of this tube anywhere that I can find. Please help, Im out of ideas!
