Briggs Flathead / Re: exhaust size?

after doing a search on exhaust i almost found my question but no answer.  i have collected several peices of stainless steel tubing.  i understand that 1" id is the ideal manifold size, however i only have two choices;  7/8" id x 1" od or 1 1/8" id x 1 1/4" od.  the 7/8" id looks too small to me but what do i know.  stock (for now) 13.5 hp flat head briggs.  exhaust system will have 1 90* and 2 45* bends.  approx 36" long.

should i use the 7/8 id or the 1 1/8 id tubing for the exhaust manifold?

Driveline / Re: two pulley vs. single pulley clutch

i plan on using a twist clutch.  there is 30 inches between the engine pulley and the transaxle pulley.  im wondering where i should put the clutch.  it would be easiest to put it in the middle.  if it should be close to the transaxle pulley, it will have to be very close, almost touching.   does that matter?  does anybody have any suggestions?

I did a search and found the link.  It wasn't what i thought it was but it was dead so i reported it.
Thanks guys.

I'm about to build a clutch for a neighborhood rider.  Thought i had it all figured out with a single pulley clutch but then i saw a double pulley clutch.  I'm wondering if that would be a better system.  With my limited lawn mower knowledge  it seems like a double pulley clutch would be more important for racing.  Any comments for or against either will be appreciated.
