1  Engine Help / Briggs Flathead / Re: Opposed pistons on: April 24, 2016, 06:02:35 PM
Is it possible to go bigger than 31ci pistons in a oppy

It's possible to go bigger,but you are pushing the limits at this point.
All I ever ran was 42ci and it was Fast

Just wondering exactly how your checking your timing? is the degree wheel attached to crank and engine running ?

13  Engine Help / Briggs Flathead / Re: Oppy with dual carbs? on: March 14, 2016, 09:32:44 AM
Now that's what I'm talking about! Nice.
 I have a set of 34's for a VW that I was going to use...not as pretty as those.
 For all you flat head guys an FYI... The pistons used in oppy's and singles cylinders are exactly the same size as stock air cooled VW's
I'll try and post a pic.
Sorry pix won't load... 3 3/8" = 85.5mm
Pic was of both pistons.

The two stock piston sizes for an oppy and a model 28 and 31 respectively are 3.4375(3 7/16") and 3.5625(3 9/16), not 3 3/8"
