    Bonanza MX

    Subaru Robin 6 hp SP-170 interchange carbs

    I'm refurbishing an ASW3170 go-kart for a friend who recently acquired it for his child. The kart has been stored outdoors for years with no gas cap and the fuel petcok 'on'. Yep, rust city inside the carb - among the worst I've seen. The motor is a 6 hp Subaru Robin SP-170. The carb is in...

    TC out of kilter

    I'm helping a friend repair a go-kart he picked up for his child. It's pretty beat, with all the usual faults. This one might deserve special mention. The TC cover is broken with a piece missing by the engine pulley. As I slowly turned the motor over to see if it was free, I saw that the...

    We've all seen the posts. Perhaps a new member introduction or someone's cry for help. Inevitably one of the quick responses that appear in the thread reads along the lines of "where do you live"? Often the justification for this is something like "well, it's so we can tell him or her where to...

    Sprockets!!!!!

    Nice kart! I would simply buy a sprocket that fits your keyway and axle, and bolt or weld a 520 sprocket to it. Here's one I once made:

    Please help identify model number of Yerf Dog

    That looks like a 2-person version of the one I have, which is a 3200 or something (I forget). I know, not much help, so here is Debbie Wasserman-Schultz's office land line: 609-386-7171 Maybe she knows. :oops:

    Need help with steering

    Not sure what you mean by the front wheels not turning at the same angles. They shouldn't, as the inside wheel describes a smaller diameter circle. Do you mean the wheels turn more to one side or the other? My Yerf-Dog did that and I needed to trim the steering arms to get the same turning...

    What are you guys, asleep? Found a rear fender - it's a front fender from some Hardley Dangerous: I was thinking of slightly stretching the frame a bit wider at the rear, where the upper end of the coilovers attach. Doing so will give more chain clearance down below. It might also let me...

    Stop flipping pictures (please)

    Here is a sample photo. I took it in portrait on my phone. I moved it to my laptop and file manager shows the thumbnail or slide show view of the photo as portrait. But uploaded here it gets flipped to landscape: The chain should be at the top.

    Stop flipping pictures (please)

    It seems that the Forum software automatically flips portrait photos to landscape. This is quite annoying when posting pictures that are - correctly - portrait. Would the Admins please look into disabling this feature. Thanks!

    School me on this carb

    I picked up this carb a few years ago for cheap. It's new. What is it, is it any good, etc., etc. I need to retrofit a carb to a 5 hp Briggs flathead kart engine that will be used on a fat-tired minibike. This little baby might do the trick - it is already set up for a cable throttle - tell me...

    I have also been wondering how to simply add adjustability to the axle mounts on the new swing arm. One idea is mocked up here - I will try my best to explain. To pull this off I will need a pair of bearing mount brackets. I could make them, but they are only like $6 each and for that small...

    Seems I can't walk by this thing in the garage without spending a few minutes on the old 'what-if?'. I grabbed some stock that was laying around as I have been wondering how the new swing arm could lay out. I inserted a long bolt through the stock swing arm mounts with a long piece of stock to...

    That's an interesting approach. Yes, the Briggs carb points straight back and I was thinking I'd angle it out towards the rear. I do have a pantload of space underneath, though. Lookee: I can put that space to good use for something. Maybe a battery and a tool box. Is there a way to...

    Sigh, today was just one of those in-for-a-penny, in-for-a-pound situations. At each step of the way I just could not resist seeing what would come along next. To pick up where we left off, the Comet driven sheave interfered with the stock left side jackshaft/swing arm mount. I could have...

    Dagnabbit, I did way too much work on this today. Things started simply enough; I cleaned the rear wheel/tire/stub axle/sprocket/brake assembly as I had sprayed it down with white lithium to prevent things from rusting years ago when I tore the Chariot apart. With everything bright and shiny...

    mounting sprocket to sprocket

    I've piggybacked sprockets. It worked fine. Here is one - the smaller was turned down to fit inside the bigger with a slight interference fit, then pressed together and welded: I realize that OP's existing donor sprocket is of a much larger diameter, but the point is that you can build them...

    So while we are kinda sorta on the topic of brakes, does anyone have experience with this drum brake: It worked really well on the Chariot, and while the total weight was quite high, the speed was only a few mph so this one worked fine.

    I found out that this is a Bonanza MX. Here's what I have in mind for a rear wheel and tire: I like the stance. I will fab a new swing arm so the stock parts can be stored for future use. With the longer wheelbase, I can fab a seat that will put my butt right where it would be on a chopper...
