13 hp pred update

Sorry to pick but that stance look a bit high in the front; that could be dangerous...

In no way do I say this to kill your mood... but that torque converter won't hold up to your horsepower.

Please consider as series 40.

you said you did the research and ordered the right torque converter - but that motor requires a comet 40 or better, not a TAV2/comet 30. i tried using a comet 30 with a 13hp motor and burned up belts like crazy till i lowered the gear ratio to like 10:1 (that's like having a 100 tooth sprocket on your axle), which gave me a top speed of a little over 20 mph. i finally upgraded to a comet 40 and life was good again. they're expensive, which is why i've switched to using snowmobile motors that already have heavy duty torque converters.

also, what is supporting the rear shocks at the top? just some heavy sheet metal? you need some serious reinforcement there, and some kind of angle-bracing to oppose the force that the shocks will put out. triangles are god in go-kart and buggy building.

what specific vehicle did those rear shocks come from (model and year, were they fronts or rears?), and how long are they?

The shocks, if I rem correctly a 2005 1/4 ton chevy.
I know somethings are hard to see in the pics, but the mounts are solid. I appreciate all the feedback. I am new at this, and I take everyones feedback seriously. I know I still have a lot of work to do, and I will eventually get everything right. I am not hard headed, and learn something new eveyday.

Thanks for the feedback.
Yeah it does have a lot of clearance, but It is really wide, hard to see in the pics, when I get the new rear axle in the mail, I will take some better pics. Rear is gonna be 45" with 4 bearings.
I thought originally I purchased a 40 series TAV, advertisement was a little misleading. Now I have one coming in the mail. I can use this one on my sons 1 seat cart. I appreciate the comments, and with you guys help, I am sure I will get it right.

Your right, I have a 40 series in the mail. Thought that is what I had, Live&learn. No loss, we can still use this one on another cart. They cost$$$. I can say one thing for sure, when you spending money you learn fast

When I purchased the TAV, it was advertised for the larger engines, I checked, and it is not being advertised no more. It was not the 1st time someone got over, or recieved something mis-leading. Now days people will do anything to make a buck, even sell someone a worn out engine, thats why I bought a new engine, and atleast got a free 2 year warranty, Full 2 year warranty no questions asked.
All is well.
I have angle Iron 2"x4" bottom to top, with thick walled pipe for shock cups, top, and bottom of the shock mounts. If you look along side of the cart, you can see the plate Iron. It is very strong, still thinking about cutting some fat from it. I did away with the old seat mount, it was like an anchor.
Now I have 40 series on the way.
Anyway what is your speed with snowmobile engine?
I appreciate you guys feedback, I am sure to get this right.

I double checked, and in the front, from outside to outside of the tires it is aprox 49", and 7" of clearance. Oh, plus I had just put in new bushings in the front, and it is still tight. I am sure when they break in it will settle down a bit.
Plus the shocks are adjusted high. I really would like some new front shocks but they are on the back burner, just spent a lot on rear axle component, and 40 series TAV.
Rear axle is due in tomorrow.
I finished the seats yesterday, Today going to jack it up, and take out the old axle, it only had 2 short keyways, and not aligned properly. I had no choice but to get another.
Thanks for the feedback, I sure do want to get it right.
I was reading that the steering mech off an Excel work great for Karts, I still have to check into it more. I may breakdown, and get a lathe from Harbor freight. I had a time just putting the shock hinges together.

I do not know if you seen the pic, of the hinges I made, but there are 3 hinges, made from thick walled pipe, they separate the cart. I used lawn mower deck bearings. 2 bearings with a spacer in each hinge with a 3/4 bolt thru each. They are welded and reinforced to bear the load, along with the angle iron, and shock mounting cups, made from heavy wall pipe cut in half. Plus I used 7018AC welding rods.

I will get some better detailed photos. I sure appreciate the feedback cause I want it right, being the 1st kart I need all the feedback I can get. I do not have any local place to buy parts, so I have to purchase everything over the net, it is not easy when having to look at pictures, but I am pretty sure I have all the correct axle parts coming in.

Will do, thanks for the tip.

with a sled engine you can easily get 55 mph with lots of torque. not sure you'd want to go THAT fast with your little kart - but it would be exciting! i've seen lots of 340cc sleds out there in the $300 price range, complete with everything. that's a heck of a lot cheaper than a new 13hp motor and comet 40 clutch! and sooooo much more power...

You just didn't.

Let him have that one, he was quoting...

 

[Kart_Doggone_Wild]

Did several test runs on the Kart. For sure gonna have to get the 22" tires on the back, the 19" just do not have enough meat they just keep on throwing roost tails of dirt, sand, grass clean up in the air. We will be taking some live video, and get it posted soon. Just have a few finishing touches to do, have to get the bug-out rack on it.

I was just wondering about what type of speed one could get. I am not wanting much high speed, just a burst here, and there. It has been awhile since I posted, and a lot of work on the kart since then. In my area there are not that many snowmobile engines around, and I been checking most of the ads, not much of anything available. I am into the kart about $600. thats with the new engine, axle, sprocket bearings, etc. I did the test run, it is powerful!! it will climb a hill no prob. I am very satisfied with the 420cc engine. The rear tires was slinging grass,dirt in the air, with 2 people onboard, and that was barely touching the gas. I have some finishing touches, and will be getting a video in the future.

I appreciate your honest advice. Now finally, I got the 40 series TC. WOW, just barely touch the foot pedal, and it burns the tires off, no belt slippage whatsoever. Plus I went with the 60T sprocket on the axle, 420 chain. I have about 18-19 inch rear tires, I am thinking of getting the 22 inch, little wider, help with traction. The wheel base is 45" Plus some, I did not want it to wide so I can drive it on my trailer. Those 1/4 ton load bearing shocks work great, plus the springs on the seat help the old back.

Thanks for your help
