Argo engine swap

[edrk213]

I haven?t worked on my Argo for awhile but I recently bought a used 620-20hp vtwin but it has a 1-1/8in shaft. Does anyone know where I might get a 1-1/8 bore clutch that will work and also any tips to installing this engine in an 80s Argo? Thanks!
I?m trying to remember how to upload pictures!

Try Richard's Relics. They have supplied me with several over the years.

Thanks Noel, I will try them. Not sure why this engine is 1-1/8, the ones I saw online were 1 inch, maybe cause it’s a clone?

Some do have 1-1/8.

I got my gx620 engine installed but now got a new problem. I had to space the engine further forward to clear oil filter and need a longer belt. Anyone know where to order belts from? I need 1-3/16?c 50-3/4? thanks!
