does anyone know if the OS .46 VX DF carb will fit the MVVS .40 GRRT rear intake engine? Are they close in any way.

here is link to carb

my problem is i have the GRRT and it is set up for WOT full time, no throttle at all. I am looking for a carb that will work with this without loosing any power. Meanning smaller bore and all. So far from the pics the bolt pattern looks the same but not sure, does anyone know for sure.

If anyone has any other ideas on how to set up for a throttle please let me know.

Thanks
