Sonaramic Briggs motor

[crossram383]

Did a lot of experimenting with milled heads,custom ground cams, and hand made tuned length intakes (dual carbs) on go-kart motors back in the late 80's.

Got back one of my motors recently.
It was my version of a Briggs Sonaramic
Probably tuned for around 3500 rpm's.

I mostly did high RPM stuff (8000+rpm)
good for 60 mph+
motors would only last about 1 hour (or until the cops showed up) runnin balls out in the train-station parking lots on sunday (no cars)
Usually the intense heat would burn the valve guides out.

Did about 4 Techumse motors and NOT ONE ever made it on to the go-kart
All GRENADED getting dialed in on the bench.
So no more Techumse's!!!
The only motors to withstand the abuse were Briggs and Stratton 5 horse motors .

Experimented a little bit with running motors on methonal and even moon-shine (Cool Blue flame out the baloney-cut straight pipe exhuast)

Yeah.....I definately had WAAAY to much time on my hands !!!!

Tecumseh is broke and gone-any wonder?

*Shrug* I always had the best luck with Tecumseh. I'm told I was in a minority. Their stuff in the '60s through mid '80s was pretty solid, in my experience, but they ate their own brain by stopping R&D after about 1988 and taking more and more money (and quality) out of the product. Dumbasses did themselves in.

Now we're seeing generic garbage engines from China coming in. Oh, yayyyy. :roll:
