I just returned to the go-kart scene after a 25 year break.....now for my 7 year old son. I acquired a Manco Dingo go-kart with a siezed motor and in need of restoration (price was right- free!). Then I "accidentally" acquired a fiberglass formula body for a go-kart (don't know what I am going to do with that yet), and now have a Clark Go-Kart frame to build up as well. That's right two karts for one kid (wish I was that lucky when I was a kid).
I ran across a package deal on a 5 hp Honda motor, 4 hp Honda motor and a 3.5 Briggs and Stratton motor- all three came off of industrial equipment ( cement mixer, water pump and pressure washer) and start on the first pull-3rd for the briggs.
My problem is that none of them have the same size shaft as the original 5hp Briggs that was on the Dingo. The 5 hp Honda has a larger diameter keyed shaft, the 4 hp has a non-keyed shaft of about the same diameter and the 3.5 Briggs has a smaller diameter shaft.
I mounted the 5 hp honda on the Dingo, but ran into a couple problems:
1) the exhaust fires directly into the back of the seat...I guess I will have to make a new exhaust pipe or figure out how to modify the existing one.
2)The comet pulley from the original briggs does not fit the shaft, so I guess I will just get a keyed pulley that fits and run it to the jackshaft. I figured out that I will have to reposition the final drive cog to the other side of the jackshaft and slide the axle gear over in order for everything to line up correctly- the shaft on the Honda motor is shorter in length and will require the pulley to be mounted closer to the engine.
I Plan on mounting the 3.5 hp Briggs on the other kart and probably just selling off the 4 hp Honda to offset the cost of new tires for the Dingo (**** things aren't cheap!) and I have no idea how to make it work with a centrifugal clutch as the shaft is not keyed.
I just sandblasted the Clark Kart and rattle canned it cherry red- looks pretty darn good if I have to say so myself. The floorpan is rusted out and in need of replacement- I am thinking about using diamond plate aluminum. The Clark kart has white rims with slicks on the rear and Harbour Freight had a great deal on replacement white wheels and tires for the front that match (the originals were badly oxidized aluminum and dry rotted tires). I will try to get some pics up asap.
