What have you guys done? Modified the stock muffler to adapt to the larger 16hp elbow? Made your own?

Thanks, did you ever hear how it sounded?

I'm a bit concerned that reheadering the stock muffler it may be too restrictive for the 16hp, but maybe not?

Also have the same concern about the heavy duty air cleaner kit.

Guess try it, adjust the carb jetting to work and go from there.

Mike,

It sounded like a small Harley ... which is good.

Gerry Reno made his muffler for the 23 HP Vanguard so it attached the same as the 140's had.

I don't know if a single would sound the same through it as the double but it may be worth a look?

Wow, thats cool, forgot about that. I would have done a duel in, single out in that case, but I guess it works.

Mike, I just used a reducer and reused the stock muffler no problems to speak of yet on my 120 and it's been to several plow days and on the snowblower the last 2 winters. I also used the original flywheel and all of the heat shields off the original K301 just had to modify for the extra head bolt on the K341 when I installed them. I also cut the ears off the block which I see you already did.

I'm going to use the 16hp blower housing as its taller for more airflow to the head. I will have to rework it some to block off the holes and get the right mounting for the coil. Will have to rework the head baffling too. Also making the throttle and choke linkages to match the 140.

Plan is to shave the head some to bump compression and do some porting and relief work too.

Still not sure what I will do for a muffler. Have always wanted to build one from scratch for something.
