Sprint 10105 20379: an update and a plan

Yesterday I watched Sprint 20379 get winched up on to a flat-bed truck and then slowly disappear from sight around a corner.  No, I didn’t sell my old friend, it is just going south for a few weeks/months of residency in the garage of Tom Sahines for an engine rebuild and a few other much needed and overdue remediations.  Didn’t I just rebuild the engine you ask?  Well, the answer to that depends on your definition of “just”.  I did rebuild the engine in the last 5 years, but I also drove the car daily on my commute for at least 6 months – not an exceptional feat for a Giulietta until you consider my commute was 70 miles each way, and I also drove it on all my incidental trips in between, probably totaling 20000 – 25000 miles in just those 6 months, but it’s not really the miles that has me rebuilding it.

Sprint surprises: Cam timing

Update 1/23/12:  In the spirit of taking one for the team -you kind reader being ‘the team’, and the ‘taking one’ is me in the form of admitting to not fully considering this subject before I wrote about it, I am writing this update.  It will be open ended and hopefully draw further discussion…

The result I was hoping for has finally happened: those with more knowledge/experience than me (Tom, Rick -thanks) have chimed in in the comments section -(though Tom, I think ‘inexperienced’ is a better word than ‘sloppy’).  The question of the cam timing had been bothering me since I wrote the first draft of this post -I even made a table to try and figure out what I was missing, but now it seems to be approaching the obvious.  For those that are spectators, or as inexperienced as me, this is what I have been thinking and why I have been thinking it.

Background on the subject:

This is the valve timing chart from the factory printed Giulietta Technical Specifications book.  Note that this timing is always based on crank position.  There are many versions of this chart for the many models over the years.

Spring Sprint sparks

It has been a long winter -this very morning it was cold and even my modern car (a full on spaceship compared to the Sprint) was somewhat inhospitable for the first 10 minutes of my drive to work as dewy windows, fogged mirrors and cold leather slowly came around.  About 6-8 weeks ago, when we had our first ‘hey it’s spring!’ weekend I decided it was time to dust the Sprint off, charge the battery, and start using it again.  Everything was going fine -it cranked over nice and fast, the carb was atomizing fuel, it had spark but it wouldn’t start.  I ended up bump starting it on my long steep driveway.  This was the first bump in a somewhat long, thoroughly bumpy road that only recently smoothed.

Starting at the happy ending… Me and the Mrs. in our Sprint on the track at Sears Point.  Thanks for the picture Greg!

Jaan’s write up of fixing the Sprint

I was checking out if Jaan made an update to his fantastic website Eddins Moto and what should I find but a pretty in depth write-up of what he did to my Sprint the week before the California Melee.  Check it out here.  You have to scroll down some, but you’ll find it starting with the picture I posted below.  The attention he gave it must have worked because I’ve been driving it to work every day without any trouble -well, a headlight burned out recently, but that’s not really trouble.

TI Tidy 6 meets Sprint Surprises

Do you ever get the feeling that somehow the powers that be have conspired against us to take away free time and purify the cycle of sleeper/worker/consumer, gleaning the little joy that used to lubricate the cycle? Well, I’ve been busy like never before and thus I am writing a post at least two days after it was thought of.

101 1300 21: sumday

First off, to address some comments: I do have the original air filter assembly, the problem is, the Solex I am using is the later type that doesn’t clear the airbox.  I suppose the correct Solex could fix the lack of an air cleaner problem too.

So, Sumday (thanks Grandaddy for coming up with that one) is the day I add it all up.  It may be premature since I haven’t fixed the possibly low oil pressure or settled on a carb, but I think I am close.  Below is a tally of work done and how much it cost.  I am presenting this as educational material for those who, like me at the outset, think they can cut corners and save some cash.  I honestly thought this would cost “about $3000”.  Pictures have little to do with this post.

sprintsssssss1I had lunch with Laurence on Friday and he thought a side-by-side of our semi-significant others would be fun and informative.  His is a Sprint Veloce made 3/58, mines a Sprint made 10/59.  Both are long term Bay Area cars with similar patina, though his is nicer in most ways.
