Finished and tested the block-off plug in the intake, works fine.
Put back the factory "Main fuel filter", taken from the '78.
'78 is on Dellorto's, only two ports were in use, no return line.
For the '79 on SPICA I think I should be using three of the ports, one with a double fitting for the return line?
Drained the 79 Spider of it's old gas, bought five gallons each of 91 Oct. pump gas (highest normally available) and five of 100 Oct. race gas.
Once I've changed the fuel filter under the tank I will put in the ten gallons and see where the gauge reads.
Car should be happy with this octane even if it is not really necessary, just seems a good idea prior to an "Italian Tuneup".
Want to keep the octane fairly high so will try to keep a mix of race fuel and the 91 Oct. Coyote Whiz they sell at the regular pumps, trying to stay around 94 Oct.
May look into 100LL aircraft fuel if it's significantly cheaper than the $6.95 Gal. race fuel.
No worry about lead, the CAT was killed and removed before I got the car.
Have heard that aircraft fuel is "Dry", so maybe a bit of Marvel Mystery Oil to benefit the SPICA pump?
Ran 100 LL in a hot-rod FIAT 850 Spider many years ago, that little buzz-bomb was addicted to 100 Oct., it quickly needed a rebuild every time I tried to get away with "Normal" gas.
Did get a short test drive in the '79 Spider a few nights ago.
Speedo is terribly inaccurate and I'm not sure the tach is much better.
Still trying to fix the water temp gauge.
Have to drill out the plunger on the Shankle Sure Start cable end as the new wire gauge is just a tad heavier.
With that done and the device installed the car should FINALLY be able to be driven, at least around town.
Days here are almost too hot for driving this time of year but I'm REALLY looking forward to some night drives!
