Not so.
I run a 12.5lb. lightened flywheel w/a counterweighted crank in my Ghia and the clutch/throttle operation is very smooth…not jerky at all. A big advantage of this setup is a noticeably improved throttle response.
There’s very little, if any, noticieable difference in overall driveability/smoothness when compared with the bone-stock 1600 in my Beetle. |
The stock heavy flywheel can be an advantage specially on smaller motors in hill climbing. the added momentum of the flywheel can help one up a hill.

I built a similar engine to this last year.
DPR 69mm CW crank, Flywheel, pressure plate - balanced.
balanced DPR rebuilt rods
DPR AC2 reground Camshaft with -3 indexed cam gear
Mahle cast pistons - balanced to .4 grams
CSP SS muffler
Autolinea DP heads - 50cc chambers
.06 Deck height - 7.7:1 compression
CB aluminum pushrods cut to fit
CB solid rocker shafts with stock rocker arms shimmed to .03 .
i built this as a practice build before my 1835 bus engine that i am working on now.
remember you will have to cut pushrods to fit your rocker arm geometry because the AC2 cam is reground so it has a smaller Base Circle.
i'm running a SOLEX BROSOL H30/31 right now and I'm pretty happy with the way it sounds and runs !

Oh sweet dude. Great photos. Many thanks.

I need to look into a sand seal perhaps. I don’t actually know what one is.
Lightened flywheel becuase thats what I got when I bought the mess of stuff.
Maybe I can find someone to buy the HPMX kit, it’s new in the box? |
I see you are in Minneapolis. If it’s the Minneapolis in the mountains I’m close to you in Burnsville. Good luck on your build whatever you decide to do 😀 |

I wonder if this could have anything to do with the carb linkage? I use Berg’s setup for dual carbs and it’s very smooth and progressive.

When quoting a post that’s loaded with pics, it’s a little easier for readers if you don’t include them all again with your comment

Thank you for the sand seal suggestion, I think thats. Good plan.
Are there any good classic (read low budget) ways to set up the breather, or is it just like anything else that needs to let out CC gases?
Thank yall. |

Keep it simple. You don't need crazy amounts of hose and breather boxes, unless you have bad rings, and hold sustained high RPM on longgggggg sweeping turns.
