Hi, I have time I want to do this with my motor. I'll do it in a j15, I know I know it is not indicated for this engine but I would leave it as it is the original that brings my wagon and I have not seen much on this engine I think that would be original. I offer a few carbs r6, but not if they are or should some of r1? this week would do this and I'll post some pictures so you can see how it turned the job.
