One final step - a dot of glue on the end of the axle:
Boop, second insert goes home and in perfect position. I don't even need to check it.
Go-Kart is done.
Time to get serious about a real job.

Hoping you don't get one that will make you work on the first Sat. of the month. LOL!!!

Good idea, Red. Also, one that doesn't have me commuting directly into the sun both coming and going.

Job search: dead
Go-Kart track test: pretty good
Power and handling were excellent, but I plan to punch the flag further forward.
John Clow's TFlex with a Contender motor was much faster, and better handling.

My solution to John Clow's Contender motor Go-Kart out-powering mine:
Stock PS 4002B arm ("Puppy Dog") comes out and in goes a Havlicek #28 AWG arm.
The H comm is about 10 thou bigger than the stock arm so brush platforms needed to be hogged out just a hair.
Otherwise, perfect fit and an easy installation.
She drew 2.7 amps at 3 volts, dropped steadily as the brush faces conformed to the bigger comm, and stabilized at 2.0 amps.
Runs perfectly smooth and cool. Sounds powerful enough to beat a Contender
Now the wheelbase needs to be punched out. Look out, John, I'm comin' for ya !

The simplest solution to extending the wheelbase is swapping the existing Chicagoland tongue for a Slick 7.
Not that one is any better than the other - but the S7 is long and that's what I need.
Should be an easy operation, but it all depends on what falls off when I apply enough heat to do it
The S7 is 10 thou thicker (taller) so the forward plumber wires cross connector will have to be changed.
Now, where did I put that doggone spare bottle of butane ?

The front plumber cross connector could be replaced or you could grind a .010 groove for the old connector to fit in. Since the S7 tongue is not as wide, you could also use longer plumber hinge tubes for added strength. I come from the days when K&S piano wire was a nickel per foot, regardless of diameter.
When chemists die, they barium.

Concur on both - good ideas, Bill But:
-I chose to replace the .032 cross connector with a new .037 piece.
-The thought of making new (doubled) plumber hinge tubes occurred to me, and I chose not to. Heck, it's a Go-Kart, not a G7
She's in the tumbler.......

Wheel insert method worked fantastic, as planned.
No failure during track test, one insert popped right off upon axle disassembly, and a dot of new glue on the axle end for reassembly.
I'll be using this method on my vintage cars for sure.

H arm in the stock PS 4002B setup is geared 7/35 with .675" OD wheels.
Center of rear axle to center of flag shaft is now 4 3/4" - same as a TFlex.
Track test #2 should be interesting

Track test # 2 results:
-Lengthening the WB greatly improved the handling Much, much better. It was out-handling the TFlex Go-Karts easily.
-H arm gave the PS 4002B motor the extra beans it needed to keep up with the "Go-Kart motor wars"
In multiple impromptu drag races down the straightaway against a G12 (box-stock) motor Kart, it was dead even every time.
Handling-wise, it walked off and left them behind. Mission accomplished.
