Timing problem

I agree with that. I did use the original one.

I was able to get the gas sediment off the sending unit with dawn. But it ate through the coating on the unit. It's $25 to replace the float, sock, rubber seal. I for $10 more I replaced the unit.

The sand or sediment sitting in the bowl of water would have clogged the carb.

The question I have is.
My radiator shop wants $150 to clean the tank
A new tank is $70

This tank has the deposits on it as shown.
I could get the deposits off of there with (oxyclean)sodium percarbonate.

Maybe the acetone will work. I'm wondering if it's even worth it.
The coating that was eaten off the sending unit also ate the float.

Would it have eaten the gas tanks in er coating.
And

Is gas acidic when it breaks down. I've never seen this problem before or I would have dropped the tank years ago and it's very easy to do and could be advised to others parking it for years at a time.

I think the gas all evaporated out totally. I put new gas in it.
It mixed with the residue.

There was no way around a quick fix with this. Even though all of it was new when I parked the car.

The seals were all dry rotted on the filler tube and sending unit.

It alsmost should have been another thread. I think this may have been a lot of the problem though.

I'll find out

I've rinsed tanks out with a garden hose before, until all the sediment is out...

Or blast it at a do-it-yourself car wash...
