    Working on it. Start up is great! Cold or warm. Usually lights off on first spin. Tip in is just a bit weak. Part throttle is wonderful! Full throttle is meh… Still dialing it in. Getting better. Wash tween requires attention to throttle for IAC as it will often change Up or down...

    Test fit before finishing….. Top flange is about 1/8” proud of the underlying trunk floor. It’s not worth it to redo or pounding up the floor to meet it. I intend to use a foam gasket. That should get me a soundproof airtight seal.

    Printer failure…..close but no cigar. Not sure if it was the printer or the file. Checked both and made some tweaks to the file. Another 20 hours to go. Also got some lettering for the air cleaner lid….. you knew I was going to do something there….. J

    Explain??? If you mean the fresh air, it’s because it’s 120 degrees cooler air going into the engine.

    Adjusted the kick down…about 3/16” of slack removed. Much better. . As it was And as it is now…. Took it out for much needed gas…. At $4/gal Ain’t she sweet…. One of my favorite views. And then…. Fixed the damned wipers… again. Went out and early voted in my local commission run...

    To be fair, the trans was sent out to the trans shop which never mounted, drove or checked it installed. Had they gotten the car to do the rebuild, I’m sure they would have caught it, fixed it, and no one would have been the wiser.

    I don’t know… tech came in at 11:00, drove it cold (worse symptoms) and had the shop put it on the lift. Ivan said he dropped the pan checked a few things, fiddled with it and closed it up before Ivan got back from lunch. Something about one of the check valves was not working right. Don’t know...

    Next up is setting the kickdown. First gear is imperceptible, second comes on at 10mph and third at 20mph. Regardless of throttle input. And yet it still moves much better than before. It takes a lot of pedal to get it to kick down…. I’d say at least 80% of travel. I think that’s way too much...

    Continuing…. It was badly pitted. Luckily my friend John (aka 75LandYacht ) had sent me a freshly powder coated lid just as I learned I needed one. Thanks John! Paint goes on… satin black to match the lid. I found that rattle can paint goes on smoother in the sun when the humidity is up...

    The big reveal!!!! Dual snorkel fresh air! The second hose finally arrived! Both are NIB replacements that match the original perfectly…. Down to the same imperfections. Just like the factory only double. The fresh air, under normal load, comes in the same way as any other ‘78. But when the...

    Not controlling the timing. What is the recommended time needed for learning?

    Question for you Sniper experts: The way it came out of the box, all throttles open up together rather that progressively. It appears you can change it to progressive by changing the connection points on the provided link. Wouldn’t progressive be more fuel efficient? Also, wouldn’t...

    Better but not by much. Had Ivan do it on Monday and report.

    Same. Although better yesterday. Come to a stop in drive, release the brake and it barely crawls forward. Give it a little gas and it engages. Strange.

    Dropped idle F/A to 13.8 from 13.5. Slight cold hesitation at throttle tip in noted. It goes back to 13.5 if the IAC adjustment doesn’t take care of it. IAC a little high. Noted it got to 80% on cold start pull away this morning. Warm IAC is around 15-20%. I’ll adjust that down a bit to warm...
