The bottom is in the bag for the next 24h 🙂 

Suggest posting .jpg files or .png vs .jfif.   The pics above opened with an app that can view .jpg files (2 below).  Notice the Cozy and RV-6(?) projects in the background.  Seller has too many projects!   🙂

Then, these Aerocad/Cozy parts relisted today by an EAA Chapter.    They would probably save a lot of work for a regular Cozy builder.   Pictures here.

I bought a project which included a Lycoming O-235 when I knew very little about homebuilts.    When I discovered the facts,  bought a rebuilt O320, and finished the project.

What nobody mentioned was SAFETY.   If you take a buddy or wife on a summer trip, maybe you stop at a nice little field to refuel; they have CHEAPER avgas.    OK, it is midday.  HOT. 

You urgently need to get up to cooler air.   You get to the runup area.    Then you realize that (1) there is no wind  (2) the runway in use when you landed has a slight slope UPHILL; well,you COULD taxi to the other end but it is HOT so maybe it is OK.   But the asphalt is BLACK so it absorbs the sunlight and there are heat waves rising from the pavement.   You and your buddy or wife weigh a total of almost 400 pounds.   Will your 100 HP get you up to the air?    In the winter or from a different airport where the fuel is more expensive or if you had picked a runway that is sloping downhill or if you are flying solo, the 100 HP could be OK.

I remember when we lost two guys that went into a "nice little airport" in the summer and filled it with fuel.    Killed them both.

Don't even think about that O-233.

I think you would a hard-pressed to see a difference from 60 pounds but the difference in HP, acceleration and climb would be quite noticeable between 116 hp and 150-160 hp.  Even the effect of putting a 200 lb person in the back seat is a little hard to discern.  The takeoff might be noticeably longer with the 200 pounder.  You might  be landing a touch faster with the 2nd person but not more than 5 kts.  But going from 150-160 hp to 116 hp would be fairly apparent.  If endurance and range was your goal, maybe the O-233 would be OK.  It's not such a difference in cruise but the extra HP really makes a difference in acceleration and climb on a hot day or a full fuel load (or a 200 pounder in the back seat).  🙂
