G'day Christo your Rover is looking good mate...Ive not done an orange briggs yet so id go with what Joe and Deejay say is a good match,dont forget to load some pics of your rover when done..Have been abit busy of late but have had mine going and seems it's revving too hard as when I engage the self propelled it spins the wheels and takes off! and I have to RUN after it! HaHa...Am looking at Buying a tach so I can Check Revs and make life a little easier working on small engines......Cheers Chris
