Shindaiwa C-4 technology fourstroke back pack blower.

Now we're getting somewhere I expect my friend in Hawaii will send one for conversion...The 34cc I converted last year was the strongest of the smaller ones, this will be stronger than the Stihl 64.9....
Oil is in the fuel, so the engine can be mounted and run in any position....

" No replacement for displacement" as the old saying goes. At 80cc even a "mild" engine is going to have a good amount of power. Just need to see how light this can be made.

It weighs a good 4 lbs heavier than the BR600, and has a lot of vibration to it. The Shindaiwa rep brought one by our store and we compared them side by side (we sell both of these brands).
