Hi again. So in light of my last topic, I have decided to repair the fuel tank rather than cut it up. Anyways, I have nover had an engine with a tank like this before and I just want to know if there is anything else I need to do to it before sealing it up. I will attach a picture of teh insides here. I would just like to know if I need a pick up tube or anything installed before putting teh back cap on permanently. I am assuming I would just need to put a fuel tube into the tank that would go to the fuel nipple up front. Any help or advice is greatly appreciated. I will not do no repairs until I know more. Thank you.

Thank you Mark. You have been a great help lately with this. If I may also ask, is it better to solder the rear tin plate on, or would JB Weld be ok.

Would it be acceptable to believe that the drive washer is pressed onto the engine as is a Cox one? I have got it apart all except for that and it will go for an antifreeze bath.... Looking forward to this. Thanks.

lol, i'd guess it would depend how well you can solder....i'd go with JB!

i'd try to heat the head really warm and remove before crock pot, as high temps will bleach dye off of anodized aluminum, you might just scrub it up with WD-40 and stiff brush, i don't think its froze?

if your going to display it, you can touch up head with a red Sharpie, this is the engine that got me into anodizing!

Ok. Just a little update. A few minutes ago I took it outside to the vise and carefully tightened it up with a block of wood behind. The thrust washer popped off nicely. So I then seperated the red head from the cylinder and put it aside. So now as i type this, the engine is sitting in the crock pot in pieces all wired together. Looking like it will be a late night.... I will just pop the red head in some old fuel I have set aside to clean as I heard that the crock pot can discolor the anodizing. Stay tuned.....

Again, thanks to Mark confirming my ideas, here is my finished fuel tank for my McCoy Baby Mac engine. I did as Mark reccommended and put the fuel line to the bottom with a 45 degree angle cut on it. I then put a piece of tin I cut in place with JB Weld and allowed to dry. Just a few minutes ago, I used a fine file to smooth it out, followed by a light sanding with 400 on a flat surface to finish it. I then did teh same to teh crankcase and made a gasket and assembled it. The only funny one is in the second picture. Right where the fuel line exits the tank, there is an extra tiny notch there (at the 3 o'clock position). It has all appearance of being factory. Can anyone confirm this, and if not, I will just add a dab of something to seal it. Thanks again.
