Ironhead Ironhead engine problem?

[Ferrous Head]

I had a 195555 175 Parilla that had been sitting for probably 40 years.

The gas inside had turned to varnish and then shellac it was that old.

The process took me about a week. But left me with a tank that looked absolutley like new steel on the inside.

If you were more diligent with sloching the mixture inside it might be quicker.

Drop some really old rusty bolts into a gas jar and experiment with them if you like.

Thanks, doodah. Will definitely consider it. It’s been 70° days and 30° mornings where I’m at, but will be getting a bit colder as winter comes along, not too bad though. Great dead reference on the name by the way.

Thanks I’m gonna give it a try. After you’re done with the process, do you rinse out the tank and let it dry?

Never introduce water into a gas tank.

The factory service manual 99484-69 recommends, for gas tank storage, rinse the tank with a 50:50 mixture of oil and gasoline. Need only a small quantity. The gasoline evaporates leaving the oil to protect the tank.

Page number 3F-35. I believe that this is not in any of the newer versions.

I guess I’ll skip the molasses and hot water tip.

Ooops, I was not thinking about the "molasses trick" and that hot water is part of the process. It is a technique that was recommended by one of this forum's top guys. I won't go against his many years of experience.

I do my final rinse with Methanol. (Metheylated Spirits).

It's hydroscopic (absorbs water). A bit of heat (in the sun or hairdryer) and then a mixture of oil and gas.

If your using the tank straight away it won't matter. Filling up the tank with gas will wash of any coating you out in there before long. Including Kreem.

Thank you, appreciate the advice
