Custom Manco Go Kart Build
Got some new parts in Thur. and Fri.,
I wanted some nylon washers to tighten up the play in the spindles. Apparently, the picture on the box doesn't necessarily mean that is what is in the box. That will never work. First guess, wrong.
Red LED Light kit with some freebies. Joe Florida koozie and stickers!
Throttle cable I had was to short to reach the mikuni carb at 60". Had to get a 72".
Was going to build a custom fuel tank over the axle next to the engine. But, I have found another use for that space. Then I ran across this tank that I think fits nicely up front.
I let the primer dry for 24hrs and then applied the wrinkle coat. Hot day and the paint started to wrinkle before I even got all the parts coated. I had the oven preheated to 200 degrees and baked them for one hour immediatly after. I left all of the masking on but coated everything with the wrinkle.
There where three bubbles on the side cover, two where on the masking and the other was from a casting mark on the casing. Scraped the bubble off and it was still coated with the wrinkle underneath.
Head looks really nice.
and block came out really nice too.
Valve cover coat was a little thin on the exhaust side, I think I can add a coat but I'm not going to worry about it.

I see what you are saying, makes it kinda hard to space the brake band out that far. I would see about having someone machine a solid single spacer that you could bolt to the sprocket and rim and then another set of holes tapped for the brake band. No idea what that would cost. I found a site that had a cross reference chart with serial numbers, model name.

If you had the vin sticker.

looks like it originally had three 5/16-18x4 and three 5/16-18x3 with three 3/8 nuts stacked as spacers between the drum and sprocket and the sprocket and wheel spacer.

Here's what I ended up doing.

It seems to work fine. There is a very slight wobble on the sprocket but it's not due to the spacers. The sprocket is slightly warped. No problems from it so far.
The engine is very strong. It spins the tire easily and then just stops accelerating at ~19 mph. It's perfect.

Looks good, nice burnout. I don't think that mine will be much different, still waiting on the order. Only 19 mph, engine is still governed. Must be for a small child. I am building for my self and shooting for a top speed of 57 mph. Don't want what little brakes there are to fail. Not sure what type of terrain you will be riding on, but switching to a 48t sprocket will give you a little more speed and help keep the chain out of the dirt. Had to change mine on my daughters kart. The sprocket and chain kept hitting rocks in the road and kinking the chain. Try to keep a good chain or you will burn through clutch sprockets. I have bought six already in one year.
Got a couple of packages. One from Hefner Racing and one from AGK. Haven't done much on the kart this week. Going to try and order engine parts from AGK this week, connecting rod, flat top piston, and billet flywheel. Still trying to find an upholsterer.
Breather filter finally came, ordered one month ago. Still waiting on indexing washers.
One inch bosses from Hefner Racing to space the brake drum.

19 is still a little fast for my 6yo. You are right about the sprocket being too close to the dirt. I can't allow it in the yard though it cuts ruts every where it goes. If I reach back and grab the governor arm, it jumps up to 30. With a 45 tooth and no gov you should be able to do 57. Not sure I would want too.
Have the same problem with my girl's Thunderkart. I am using the Hilliard extreme duty clutch. Not sure about others, but on Hilliard clutches, you can change out the engagement springs. I think stock is 2800 rpm. I bought three different sets to try out. I think they is 1500, 1800 and 2100 rpm springs. I haven't tried them out yet, but I think that the reason for the ruts is that the clutch fully engages at too high an rmp. I thought that if it fully engaged at a low rpm, it would cut down on the ruts. Also upgrading to a mikuni carb will give you a lot more throttle control and alow you to idle at a lower rpm. Just my thoughts, haven't had a chance to try out my theories yet.
