Hello, MA-troops!

My '76 DEMM Smily is running and rolling! I can zoom along at 25 mph on flat, but slow to a dead stop on long/steep hills. Engine still runs well (no bogging or backfire), but there's no power to get moving on the hill. I have to pedal a bit and then walk it up the rest of the way.

Details...

NOS OEM muffler just put on (only 15-20 miles on it)

14.12 SHA sparkling with no blockages

Stock no-angle/cutaway slide

Stock Smily 53 jet

New float needle

New Banjo filter

Very tiny air leak at carb to intake pipe (waiting on an O-ring to seal that up today)

No other air leaks (new base, head, exhaust gaskets)

Cylinder and piston are quite shiny

RIngs ok (small sign of blowback at first ring, but is mostly stopped by ring two

Fuel is good and flowing well

Smily asks for 20:1 ratio

Timing and point gap darn close to stock

Plug gap in spec

Brakes don't seem to drag, but I am replacing pads this week.

What am I missing?

Thanks for any advice and help!

Be safe and be kind.

Peace,

Pea-Jae
