i ran a billet dogbone with a stock (good) rod for three seasons on an un-governed engine with no failures whatsoever, wouldnt have bothered me at all to throw a cam in it along with a billet flywheel, but rules didnt permit it, even the 28's will shake at certain rpm's with the brass weights, on most i have seen it is low in the rpm band around 2500 rpm, but ya seldom ever see that rpm in a race engine so its never an issue, be fore warned tho if the counter weights do decide to vacate the block rest assure they will take everything with them including that high dollar cam, and dont be scared of the good briggs stock rod, George ran them a long time before arc came out with the billet rod!
i also had a 31'' with the 1.25'' crank in it, so they do exist, just not sure how common they are!

ya the 31 rod in this engine looks likes brand new and going to reuse.Getting the engine line bored for new .20 over pistion .I can't wait till next year new engine and sand blasted complete frame, powder coated and candy apple paint on my mini craftsman.Complete mower weighted 174 pounds and it will probly drop to 160.Going to be a rocket.We have no points races up here and we have a couple racers with modifed engines so i'm hoping for so tight racing.. :D

With a stock rod, my personal preference would be to use stock crank and weights with the arc dogbone. Keep in mind the harder you turn the motor the more is at risk.

I'm going to use the billet dogbone this coming year and next year get the crank balanced out of a 28 cube because there way easier to get my hands on for cheap.I only seen one of these 31 non avs cubes in the last 3 years so i had to have it and the price was right at 75 bucks..It;s going to cost me 300 plus probably to ship and get balanced.

i don't think any briggs singles are presure lube.the oil filter only cleans sump oil,and they still have a oil slinger.cheak your messages.
