Go-kart noob here

[Prone2Problems]

Ok so back when I was a wee lad (8 years old) an old neighbor asked my dad if he could have a snowblower that had been sitting in our garage unused.my dad said sure.neighbor in turn used the motor for a jimmy-rigged go-kart that he welded together from scrap metal he found in his garage.i used it about 3 times then lost interest because it was too hard for me to start so it sat in our garage.

Fast forward 22 years later...lmao
I dug it out,brought it to my house since I finally have a garage of my own.first things I did was regular maintenance​...spark plug,oil,fuel filter and line.couldnt believe it but this vintage B&S engine actually started.

Now the old frame I WILL NOT use because of it's shoddiness.But I did recently pick up a Manco 606 frame in very good shape.it needs the complete rear axle (minus brake caliper), front hub,all 4 wheels and the seat.not bad for $70.since I am totally new to this gokart thing,I will need help figuring out parts for the axle and front spindles.so what do you guys think?

Hmmm that's a great frame! Also, the good news is that all of the parts (with the exception of the motor mount/jackshaft) are fairly generic. So 1" axle, standard mechanical disc brakes, 41/420p axle/jackshaft sprockets, bearings (1" ID rear, 1 3/8" od fronts), 6" disc all can be of the generic kind. You DONT need a hex axle singe its missing everything else, so a cheaper/more common way woudl be go with the 1" keyed axle and build everything on the rear from there with no issues with compatibility.

The predator 212cc engine would be a good replacement engine for that kart, but the way the original mount was built, may hamper your ability to just plop it on what you have there, so again, that jackshaft/plate thing would be a great thing to have. If not, you could weld up a little motor mount plate or purchase one from BMI karts

something like that would work if you couldn't source the actual manco part.

Throttle cable you could get form go power sports, they have long manco ones, and possibly the seat (two different bench style seats were made by manco, the not so wide ones, and the wide ones. yours may be either one, but just look on the gopowersports site under seats and you will see two different bench seats, they bolt on to the existing seat sliders.... whiiich you dont have. So that would need to be a genuine replacement as well.

Before i get ahead of myself, the predator 212cc from harbor freight (~100$) is really the general/all around good replacement for whatever was on that originally and will simply bolt on. I have put larger engines on karts of that size, and it does take some fab skills to mount a bigger engine, up to and including chopping out a portion of the rear of the frame to make room. If thats not your cup of tea, the predator will suffice,

Now to the 30 series torque converter (if you are using the predator 212cc) cheapest is ebay for about 70-120$, and you can ditch the back plate in place of the existing jackshaft assembly. If you do use the back plate that comes with the 30 series, you may have serious issues with the axle sprocket not having enough clearance as the motor mount without the jackshaft plate is pretty LOW.

so gearing (30 series comes with the 10t 40/41/420p and a 12t #35, you use the 10t, or you ditch the 10t for a 9t or 8t type c sprocket for the jackshaft for lower speed and more torque. Axle sprocket on manco was the 54t typically, but more common now are the 60t. You get a little bit less ground clearance though. so jackshaft/axle sprocket could be 8t/54t or 9t/54t or 8t/60t, or 9t/60t, or 10t/60t ANY one of these combinations will give you a great gear ratio.
8t/60t will give you a top speed of about 28-30mph, and 9t/54t or 10t/60t will give you about 35 mph. I would actually prefer the slower one because it accelerates faster and can climb things better.
rear tires/rims should be 8" rims with 18" v tread or knobby tires
front tires.rims should be 6" rims with bearings (1 3/8"OD, 5/8"ID) sealed. front tires can be either 145/70-6 or (i like these better the 15x6-6 turf savers).

shocks are also generic size, so you are bound to find them by searching for azuza go kart shocks, they will be all black.

Front rims will likely need to be spaced away from the spindle with a 5/8"ID spacer (16ga 3/4" pipe works).

Hope that gets you started. Not sure about seat belts, but since you have a roll cage, it might be a good idea to get some.

It looks like it should be a fun journey. These clowns should be able to help you right along.

We both posted at exactly the same time.
Mine should've been first.

O wow.this is great.thank you so much for the info.

For now I am planning to reuse the 8hp B&S I have.Figured I got it to run and if I gear it right it should do the job.Just hope it won't take any special fabbing to mount it (I don't know welding).
