    Dirty Head Stud Threads

    @karl ,@Flyinhillbilly , I'm putting together the Raptor with the parts you guys sent, but I've run into an issue. I'm installing the head studs, but I need to know what the thread pattern is on the threads. On the corner of the exhaust port, the stud gets stuck about 11 threads down. Visually...

    Intake Hose.....Tube.....Thingy.....HELP?

    So I almost have everything in place to assemble the Raptor, except an intake piece. I have a 28mm PWK flatslide carburetor, which is what Flyinhillbilly used to run on this same engine. He was also kind enough to include the intake manifold. Now I have a problem, I don't have the hose thingy to...

    Warbird Projects of mine

    Yes, that's right. I've been working on World War 2 aircraft! Big step up from go karts! I've started spending every weekend volunteering at the Vintage Flying Museum in Fort Worth, since I'm planning to become and aircraft A&P mechanic (Airframe and Powerplant). This is very valuable experience...

    Tillotson HL19D Resources

    All right guys, I finally got the HL19D carburetor mounted in the Hothead and got it to start up!! One problem though- It dumps fuel out the intake. :/ So I need to open this thing up and stop the huge leaks, so that brings me to the reason I'm making this thread. Anyone know which rebuild kit...

    Hybrid Kart Brainstorming

    So after seeing a bunch of cool hybrid and twin turbo type cars at the Petersen Automotive Museum here in L.A I've latched onto the idea of turning the Green Monster into a hybrid go kart, so this'll be my thread to crowdsource and get input on my ideas and designs. @Functional Artist I know...

    Visited the Rose Bowl!!

    Well I'm back after a break from the forum (school and whatnot, yada yada) and I'm on vacation in sunny Los Angeles California! Well I found out we're staying 20 minutes away from the Rose Bowl, so I convinced my grandpa to take me down there! For those who don't know, Art Ingels, the creator...

    ARC Rod Bearing Replacement

    So I've got pretty much all the parts I need to start building the Raptor that Flyinhillbilly sent me, but I've got one critical question before I start: How do I replace the rod bearings? I've got fresh ones, but I don't know how to get the old ones out without prying on them and I'm not about...

    Weird Hardware??

    This is a simple question: How do I mount the number plate onto these tabs? I have no idea how to mount to these!

    Race Kart ID

    So I'm trying to ID the "Green Monster", so I figured the best way to do that is to start a thread dedicated to it. In short: Anyone know what race kart this is?? I'm 80% sure it's an Emmick, since it says Emmick on the seat and I see some similarities with other Emmicks, but I'm not certain...

    Gaming Chitchat

    So basically I'm just curious how many people in the DYGK community are also gamers. This thread can also be used for miscellaneous gaming talk. This past year I had a pretty nice PC gifted to me from a friend, and he introduced me to "proper" gaming. Up until then I'd basically just done dinky...

    Race Kart Refurb | New Project!

    All right I did it again! This time my friends gave me their Predator 212 race kart FOR FREE as a late Christmas gift!! :banana: If you think you recognize it, you're right! I raced my friends with this kart awhile back! I completely DUSTED them with the Hothead when they brought this kart over...

    Tillotson Briggs Throttle Hookup

    So I finally got all the pieces (I think) to put my Tillotson HL-19D carburetor on the Hothead, but I can't figure out the throttle linkage. I've seen this same style throttle kit elsewhere than EC Carburetors, but I can't figure it out. There were no instructions included. So this one is...

    BBR's Jeep Bike!

    Yay for Briggs!!

    Great news! I contacted EC Carburetors, and they’re making more Briggs to Mikuni billet manifolds!! :bannana: They said they’re redesigning it without the angle per request, hopefully that won’t cause fitment issues. But this means there’ll be a commercially available Briggs mikuni kit!!! And it...

    WTB: Genuine 22mm Mikuni + Other Parts

    I'm in the market for a genuine Mikuni 22mm carburetor, I'm planning to make my own intake runner, but I want one of the real ones. Note that I'd be willing to buy a Chinese one in the meantime, but I'd pay a pretty low price. Other things I'm interested in: Briggs stock length ARC billet con...

    First Welder!

    Yup, I finally got my first welder! For $200, I got a Century FC-90, as a late birthday present! My dad also got me this big Husky bin to keep everything in. Of course, I have a full complement of safety gear, and we even cleaned the automotive fluid stains off the garage floor before I ran a...

    Go Kart Street Racing!!

    So out of a total surprise today, my church friends came over today with their race kart(it's actually the bishop and his son LOL). They technically broke the local shelter in place order, but oh well. They mostly brought it over so I could help them fix a major gas leak. What had happened was...

    Bird Engineering Starbirds

    So I keep finding more and more Bird Engineering Starbirds on the internet, so instead of updating a post in my Build Off thread, I'll use this thread instead. Don't worry if it's rather empty now, it's a work in progress. Here's a list of all known Starbirds(it's become a microhobby to me to...
