cool beans.

In fact, mine is wearing a different top end now. I gotta finish it up sometime, but I got several to get off the bench first.

I swapped carbs, raised the uppers, and adjusted the timming. What a difference. JWyounger shure liked it.

I'm hopein the next buildoff goes a lil better fer me. Bout got this stuff fingered out. Always learnin sumthin new though.

Amazing the transfer numbers these things like.

FWIW, my stock jug had 15 degrees blowdown. :msp_scared:

When u quit learning, your in trouble....

The earliest 046 jugs had extremely low blowdown. Like I said, mine was 15 stock. IIRC, it was at 102/117/75 to begin with.

As the muffler outlets got smaller(i.e. MS460) the blow down increased. Ive seen the MS460 jugs with as much as 25 degrees blowdown stock.

There are several different 046/460 casting as well. Ive seen 5 different ones myself.
