Old gas

[smf]

I posted awhile back about my 67 not starting up properly. I've been reading some posts on the forum I use for my bike and I saw something that made me think.
Old gas. I can't remember when the last time I put good fuel in the car. I'm thinking about a year and a half ago. (Not a good idea). I was reading about how old gas will make an engine run horribly. I'm thinking this could be some of the problem with my 67. Is this a possibility? Do I drain what is in the car and try new? Just add some new? Any additives I should try?
I've said my apologize to the Porsche Gods for neglecting the poor old thing. I started riding motorcycles again and I haven't stopped. I've learn so much over the past year about taking care of my bike. One night while I was in the garage working on my bike I looked over at the Porsche, thought, "Wow, that’s way too nice to just sit. What am I saving it for”? So, now if I not riding my bike, I'll be having just as much fun driving the Red Ripper. I just need for it to come back to life.
Sorry to ramble.

Dump the old fuel (sorry gas for you usa guys), check for rusted bits in the tank. Put some fresh fuel back in and drive the pants off it. It's the only way to find out what problems you have. Plus it's fun.

I don't know what they have done to the gas, but it takes very little time for it to go bad. A long time ago, when I started fooling with cars, it lasted a long time. With a 912, it becomes a big problem as the filter, which screws into the tank, is very fine and will clog easily, and you wouldn't believe how much mess will accumulate on the bottom of your tank. If you are out driving when this happens, you might have a long walk ahead of you. There are several solutions. The easiest is to drain the tank, remove the filter from the hose connection, put an in line filter in the engine bay, and fill with new gas. A better solution would be remove the tank, which isn't real difficult, and clean it out. Get a gallon of the strongest carb cleaner you can find, pour it into the tank, shake it around, and then let it sit. Do the shake and sit thing several times and pour it out. Then fill it about 1/4 full with water and a strong detergent. Get some clean coarse gravel, put it in the tank and shake it around like hell. Do this several times, rinse and dry thoroughly, and put it back into the car. The easy way is to buy a new galvanized tank from Performance Products for $299.95. I just got one for my 912 and it looks great.
