Sure he needs one! He just don’t know or realize it yet.
Adjustable pedals?

Didn't realize that your engine has a 5/8" crankshaft. That is probably going to be a problem. The links you posted say it works with both, but then list the driver as 3/4" & the driven as 5 /8" like all of them are. I have heard of adapters,
but have also heard that they don't work because you need one key way to.keep it on the engine shaft and another key to accept the driver. You need to research 5/8 to 3/4 adapter. Or bite the bullet and buy a 212cc predator engine.
I know that isn't what you had in mind, but you could still limit throttle travel enough to keep the kart slowed way down. So you don't think I am blowing smoke, I have included pictures of almost 15 years ago. Feb. 2009. Bigger grandson is not quite 5. Kart is powered by a 196cc 6.5 hp. clone engine. Same thing as a 6.5 hp. Predator. If you buy it now and tone it back for starters,
you'll be ready for a year and a half from now when it's " not fast enough ".

Don’t underetimate 3hp. Geared right it will propel the machine just fine.
lt wont amaze you with acceleration, but it will be fine for a beginner. It’ll get you through the first season. Since ya already have the stuff.
nevermind Denny, the drives vettes, Lambos, Those itialian Fn things. Rumor has it his DD is a Bugati Verion.

True dat!
Oh I believe you, no doubt there. Yeah in hind sight a 212 would have been better considering the torque converter adaptation. Just sucks that there isn't a 5/8 driver in a kit. Yeah I don't an adapter would work well either. I already looked into that. Lol
I hear ya. I may just go ahead with the centrifugal clutch I have for now and look at upgrading motor and clutch next year. It's not ideal, but I'm running out of time due to the season changes, if I want her to start getting used to the new platform.

Look at this and see if it will work for ya. I think there is an extra around here somehere.

How to fix your shaft
If your shaft has been damaged, hacked or just isn’t as long as it should be, get your mind out of the gutter and follow along. the shaft on my lttle Briggs motor was all of the above, so l wittled out this little fix. lt looks like this on the Briggs. tomorrow l’ll make some spacers and...

Like h#ll papa don't need a mini bike. Here is a picture from Jan. 2023. Same kart is next to last on the left. My older son and his daughters. Look right in the middle. PAPA, me on my mini bike. Went out and bought it brand new. Know why? So I could keep tabs on grandkids. I have 5, and that is probably all. You already have 4, and with 6 children you might plenty more in the future. That
79 cc engine and centrifugal clutch will go real good in the bike frame you should buy for PAPA'S brand new mini bike. I am LMAO as I write this, but am also quite serious.

Hahaha I'm not saying your wrong, just didn't plan on doing a mini bike as well. Yeah with 6 kids, you'd think we'd have more grandkids, but not sure that's gonna happen. We will see.
I don't know what I'm going to do. Good thing is, I have enough small things to retrofit between now and then. Currently working on a seat, and then working on the moveable pedals. Good times! I appreciate all your feedback and suggestions.
That was interesting fix. I may have to look into that. Luckily, I have a buddy who is more than capable on a metal lathe to perhaps offer assistance. The side chatter was hilarious btw!

Master Hack is also a purdy smart guy. His broken shaft extender looks like it might just fix your problem. Keep the new 3/4" section as close to the engine as possible because you can only move the driven out so far.

Just another option. Bottom line is the bigger engine is gonna happen at some point.
The shaft thingy and a few spacers can be made in an hour or two. If it gets ya running before winter sets in….
That thing is still on that little 3hp.

If it's not fast enough, you're not paying attention to trends. There's tons of modded electric Powerwheels/Barbie Jeeps on Youtube with upgraded motors (and upgraded batteries too for longer run times). There's a kid that drives a modded-out Lightning McQueen car that is at least 10X faster than stock.
On the gas kart, I wouldn't attempt adjustable pedals per se, but just mount a separate pair of pedals close to where she can reach them now with her legs bent. For example, drill two longitudinal holes in the frame for the gas and brake pedal to where the driver can reach them now and connect them to the main (adult) pedals with threaded link rods. So, two gas pedals same distance apart, linked, and the same for the brake pedal.
I say place them at a fixed distance because average height adults think most karts are too small because they think they should be able to stretch their legs out straight, no bends, but you're supposed to assume the crouch/squat position to ride these things.
The photo in post #8 is basically what I mean:

Thanks for your input. I like that idea and it was very close to what I was thinking originally. My lack of experience and knowledge is a hindrance and led me here to ask advice.
Ok after watching some YouTube videos I found several that put on a 212 or 224 torque converter on a79cc engine. They bought a 5/8 to 3/4 sleeve with key from Amazon.
After a quick search, I found both parts and orders them. So, the plan is now is to install the sleeve and torque converter on the 79cc engine, after I do the governor delete. Then, if I have to update to a 5hp or more next year or two, I will do so, and save the 79cc, along with the centrifugal clutch for a mini bike project for me (Papa) it I find one cheap. Lol
Thank you to everyone who commented and provided help for my situation. There will be more posts to follow, I am most sure of that. Thank you again! Y'all are just awesome!

Pancho was exactly who I had in mind when I wrote about building a bike for you! I remember his story about how the other reindeer would not let him join in the reindeer games.
Oh wait, that’s the wrong story. Here’s the right one. He would cry because the kids were mean to him and would not share their wonderful toys with him. So he showed em how it’s done! Old school style!
And Terry, I have never owned a foreign car in my life. All GM, 3 Chryslers and 3 Fords. Over 1,000 in all. Mostly big blocks!

I love this photo. Totally what DIYGKs is about. Everyone looks like they’re having a great time.
Ok, quick update!
I went to put the 79cc engine on the cart for a mock up. I noticed oil on the bench the engine was sitting on. Upon inspection, I found a crack in the case. I returned the engine and upgraded to a predator 212.
Now, in the meantime the torque converter showed up. I read the instructions and followed it precisely. On the driven side, I put on the washer and the spacer as described. However, I noticed that the inside surface of the driver side and the driven side (I think that's what they are called) we're not parallel. Having the inside surfaces not parallel didn't make sense. So I shimmed the driver side as close as I could to the driven side.
Was I correct in doing this? Or should I have left it how the directions indicated, since the bell expands as the revolutions increase?

You got to do what you got to do sometimes. Glad things worked out for you! Just use a Genuine Comet belt!
