UPDATE**VICTORY IS MINE**
Judicious application of heat with a propane torch solved the problem.Wrapped the rod in canvas padding,locked it a vice and put to it.When the oil boiled out after a few short cycles of heat and twist on the bolt with vice grips it finally broke loose.No visible galling /contaminated threading of any kind.
New bolts and gaskets in the mail,it will be wearing the rod before it returns to duty as a heavily upgraded yard basher. If there is interest I will post some pics of the upgrades done when back together.
Thanks for all your time folks.

Hey Fellow Cool Kids
So,I am "refreshing" a Yerf 3203 .."for the kids"(12/13,both giants for their age).Its had opened up lungs for a bit,carb, header,filter etc.
Any who,being the awesome Dad I am,the HF Pred 212 (hemi) now has billet flywheel,.010 head gasket,22lb valve springs,CS grind Dynocam,gov/oil sensor delete and WOULD HAVE this nice ARC con rod....you know...for the kids,honey.
However..I managed to snap a d#@$ bolt off in the con rod.Blame the HF torque wrench,thats what I did.
I have the stock rod in for now,just so I could run the motor on the bench for 20 mins to bake the hi-temp paint i put on the header(got tired of watching the $50 rust away).The Kart is stripped of wiring,lights etc as I custom built some tie rods out of steel pipe /welded heim joints(jumping ditches is not good for all thread stock rods...standard QC method here) ,beefed up the spindles with some gussets,fully welded the spindle brackets on the a arms and getting a nice 100 can Rustoleum paint job.
I CANT GET THE D@#$ BOLT OUT.
Ive never fooled with aluminum anything,so forgive my ignorance. With such a small workpiece I dont want to drill/tap and the bolt seems brittle to the point I am worried to weld a nut on it,as I dont want the last little nubbin to break off in the rod.
Can you safely use heat(Im thinking mini propane torch,not MAP gas) on the aluminum to get it out maybe?
Vice grips,of which I have many breeds,just round off no matter how tight I get them.
Tips?Tricks?Ancient machinery gods that accept scrap metal sacrifices?
Also-thoughts on the stock rod,safe AT ALL to put into play around our yard,or no bueno?Any one run a stock rod hard at 6-7k RPM?
I dont think they have enough room to wind it out ,but children are as impressive as pickled adults when it comes to destructive testing.
