Good Morning All,
I am new to the site... My dad bought a Mc Pro 700 in 1976 and has always taken good care of it. Last year, he had a few trees he needed to cut down, but when he finished he forgot to drain the fuel tank. (gas with 10% ethanol) We now have a place we can purchase 100% gasoline... which we use in everything now. Anyway, he remembered the other day that he forgot to drain it, and when he opened the gas tank lid, there was jelly everywhere. He was not looking to invest the time and money into fixing the saw, so instead he passed this treasure down to me... I've always wanted the saw anyway because of all the childhood memories we had together using this saw growing up. The saw really is in great condition and has not been abused.. just normal use now and then. The recoil spring was very weak and it needed a new pull string as the old one had broken before and was too short for me. So after finding Randy's Repair on Ebay, I ordered a new Fuel line w/ filter and a recoil spring. After some trial and error, I got the recoil spring in and working great....
So now, to the point... I pulled the top half of the gas tank off, only to realize that there wasnt just "jelly" in the tank... the paint was also peeling off the whole inside of the tank. I started with some carb cleaner and rags working for a few hours and got most of it out. The CORK gasket is shot.. and there is a black gasket that is also shot that goes around the back area that houses the carb. Do I HAVE to replace with a CORK gasket? Where can I get one? I looked around and found a thread about using Seal-All verses other products etc. but there was a lot of back and forth about this and that product... And the second part of my question is, would you just try and get the rest of the paint out and leave it bare metal?
Thanks for any help you can give... I am attaching some pictures as well. I got most of the jelly out before I pulled the tank and took some pictures. The last picture isnt me finished cleaning it, i just ran out of time.
