105HZ, convert it to HZ-R, what...

[trollycamber]

I have a 105HZ and a 91HZ-R, I want to convert the 105 to HZ-R with parts from the 91HZ-R, how different are the carbs other than the regulator?

If it's the 91 speed, I think it's the same. I'm not sure about the standard HZ-R though.

The 91HZ-R 3D Speed uses the same Carb as the 1.05HZ-R, which is the 61G.

The original 91HZ-R uses the 61ER carburetor.

The difference between the 61ER and 61G is the Carb Body, Mixture Control valve, and the Rotor.

OK, great info, but what about the carb on my 105HZ, should I just swap out the regulator from my 91HZ-R, use the complete carb regulated system from the 91HZ-R, or just buy a new 105 HZ-R carburetor?

Which carbureta is the best to use on the os105, the 91HZ-R or the 105HZ with regulator added?

Based on Darrik's post, quoted below, I would guess neither of those two. If I was going to do it, I would order the 61G from the 91HZ-R 3D Speed & 105HZ-R.
