hi guys,

heres the torque values for a mc motor as set forth by Mike Savin in his booklet "Speed Secrets and Tuning Tips"

torque values
Coil/lamination Screws ------------55-60 inch pounds
Condenser screws ----------------30-35 inch pounds
Con rod - mc49 mc 91 -------------105-110 inch pounds *
Con rod - mc101 ---------------90-95 inch pounds *
*torquing to 110 possibly could result in a cracked caps.i myself do 85-90 inch pounds
Crankcase End Cover Screws --------60-65 inch pounds

  coil gap .018" and points .018" to start with before timing is set. Make sure your timing light is firing when the timing mark on your flywheel hits the front side of the magnet going from left to right. This will give you a good spark and ensure your timing is not advanced to far.

To test your condensor you can take a multimeter set on ohm's to charge your condensor (capacitor) by placing the negative lead on the mounting screw and the positive lead of the multimeter on your condensor lead while it is not hooked up. You should be seeing your meter take incremental readings until it over loads.  Quickly switch back to voltage DC and watch your voltage drop back to zero.  This will give you an indication if your condensor is still good.

WOW,
I HAD A blast.
The Orville Kart Club held their second vintage race this last weekend.

As usual Orville produced a stellar event.
And why shouldn't they the track has been around since forever and their YEARS of experience shines through.
there was at least forty drivers up from 30 last year  (their very first vintage event).
The Event well run not a single track issue.

The interesting part was most of the vintage drivers there aren't seen Anywhere but the East Coast.
there were even some at their very first vintage event ,drivers that have the equipment from years ago who are EXCITED to get to run again.

That's not to say they aren't fast or experienced , they are all of that , just new faces to vintage local to the area.
While nobody was out to win at all costs they weren't shy about driving to the limits of their machines potential.
Possibly the best grid was the rear engines , with several serious drivers duking it out for the checker.
The yamaha grid was probably equally exciting but i prefer the older karts myself.

Orville applied the Upper East Coast idea of one fee for multiple grid entries.
This encouraged multiple kart entries by lowering entry costs.

This year many of the drivers (New and old) brought more than one kart to compete.
This single pay multiple entry fee produces more kart entries and makes for a far more interesting event spectator wise.
Plus it is appealing to vintage kart owners that have multiple karts but a small pocketbook.

There was a kart Show with some absolutely beautiful entries.
Hopefully Rolf H. or Karl G.will jump in and provide the names and karts of the winners in the kart show.
i was too busy with carb issues to see who won but i definitely would've hated having to judge.
i would've never been able to pick a winner the best karts were that well done.

The catered food on saturday was stellar with a menu of Grilled Chicken , Ziti , Potato salad, noodle/veggi picnic salad , green salad , chips and prezels.
Way more food than you could want too.


On the "race grids"
Last year Orville basically had the yamaha class and rear engine class.
For a first year event that was really good with about 30 drivers attending.
as the word got out this year More drivers scheduled going to Orville and the event was well attended.
Orville added ten more drivers this year a 30% increase.

There was a decent field in historics , sidewinder straight axle , sidewinder y-axle , yamaha competitive and exhibition , even a couple of c-open duals.
There were so many rear karts that the field was split for the heat race grid.

When it was all over there were even trophies for the winners.
the trophies are something i don't see as needed but i'm in the minority.
Hopefully Alex will step in with the race results and Maybe on of his excellent race narratives.
i can report on the event but he's great with describing the actual track action!!

All in All it was a well run action packed fun event.

respectfully

Blue frame in pic.

found this early go kart 400 with a mcculloch conversion, has jackshaft setup both rear wheel drive, right wheel jackshaft sprocket is a one way bearing to allow easy turning, this was built in the late 50s, found in ontario ca. this kart is in great original shape.

Steve and Shawn ran in the Vintage Open Kart Class. This is video filmed from Turn 6, probably one of the best turns to watch from. Shawn is in the blue #6 and Steve is in the #8, running the old 1960s style rear engine karts that do not handle like the rest of the field of sidewinders. Boone Rule and Aaron Kruger were staying right there with their more modern Yamaha karts. https://youtu.be/ZG6whtjANOk

Tom Day ended up winning this race in the 100cc Mac & Single Rear Engine class at the Rock Island Grand Prix. Good group of racers having fun driving the old karts on the street. https://youtu.be/U1yyihWmGhk
