4020D fuel injector

[Z. Robinson]

R-M Model CBC is leaking fuel thru the seam where it's mounted on the right rear of engine block. I understand there's an O-ring seal between them. Is this a primary fuel seal? Can I lift the injector pump to replace O-ring without disturbing timing or creating other problems?

Thanks.

No. Will have to come off.Probably the governor thrust button o-ring. Takes a special tool to reset the throttle linkage after the o-ring is replaced.
