I recently stripped down my Rover Rider Heavy Duty. The engine that was on it was a Honda G400 and too big for the machine. You can see where it had been held on by three bolts on a wide angle. What has surprised me is the original holes are also on a slightly eccentric angle. Those holes were for B&S 4135-170402 (7HP) and 4148-19042 and 195432 (8HP) and Honda 4190-G300 QZDF (7HP). Yet when I look at the parts diagram for the Heavy Duty it clearly shows the mounting holes perfectly straight on the plate. So I am a bit confused. Has my plate been replaced at some time? It was obviously extended by an operator at some point in time, with an extra piece welded on to cater for the massive Honda G400.
Is that normal for the engine to be running on a slight angle to the transmission belt? I'd guess it is around an 8 degree angle, off square. It is hard to tell from the photos from the time if the engine was straight or on a slight angle.
Of course the new Chonda engine has entirely different mounting holes and the drive shaft is about 2 inches too low. I see that I can get a riser for my new GX160/200 Honda clone, which raises it a full 2". I may have to buy one or get one made.
P.S. Hopefully Chonda have the same mounting holes as Honda GX160/200?
