    Do Heavy Valve Springs Cause Cam Wear?

    In the end, it is more force being transmitted through the valvetrain, so like Denny said, you'll probably see some increased wear. Although keep in mind we're talking about hardened and precision machined engine parts, so they'll still last awhile if you take care of them.

    Nah I was asking if the frame has any problems with twisting under high Gs/hard cornering.

    Purple hornet

    :O that's an unusual looking kart, did you make it yourself? Do you have any problems with torsional stiffness?

    Quick bits

    Hahaaaa I wake up at 4:30 AM for religious seminary each morning, go to school till 3, ride the bus home, do chores, maybe a nap, Taekwondo black belt training for an hour or two until 9ish, then back to bed and restart. Saturdays I'm at the museum all day doing everything from washing the T-33...

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

    Haha I am NOT suffering through wire formed clamps, those things SUCK in my experience. I'm going with screw worm clamps.

    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...

    Welder purchase advice?

    I honestly don't get why people don't like them. I have had zero issues with mine, it far overperforms what I expected for the price.

    Welder purchase advice?

    Look at the Century FC-90. It's a sub brand of Lincoln Electric, and it's a very nicely built little welder. It's what I use, and even with 90 amps I have legitimately blown holes in my metal while practicing! Needless to say it's got some nice power. It's about $200 MSRP, more than the Harbor...

    ARC Rod Bearing Replacement

    They work just fine for engine stuff! Click style wrenches are just more convenient is all, but as a whole beam style is more flexible, and I know the Craftsman one I mentioned clears a Briggs 5 HP crankcase. Can't speak for Predators though as I haven't torn one all the way down yet.

    ARC Rod Bearing Replacement

    Try Craftsman 44690. 3/8" drive. It's what I use, and goes up to 75 ft/lbs. Great wrench!

    ARC Rod Bearing Replacement

    Get yerself a nice Craftsman deflection-type torque wrench. With the specified 1/4" 12 point socket it clears the case with a little bit of room, but not much. Enough to work with though.

    Tillotson 225

    I concur! I like going to racing companies since they focus on quality and performance, and they are usually very good with customer service. EC Carburetors and ARC are good examples, they're so good their reputation kinda precedes them so they don't have to market much. Plus who doesn't like a...

    Never had problems with GPS or OMB, might just be lucky, IDK.

    Tillotson 225

    They're nice, albeit pricey and a little too mainstream for my tastes. I've been to their HQ in Keller, very cool place. They even had a preserved twin engine McCulloch race kart! Here's hoping they don't try to stick a Predator on it..... :roflol:

    how hard is it to flip an engine?

    I sincerely want to buy a whole crate of RC airplane sized jet engines to stick onto things >_>

    Warbird Projects of mine

    I will fly in ANYTHING if I think I can. Not even kidding. I'm not okay..... Also I put the picture through a colorizing application, turned out pretty nice! Cross-referencing with other photos from the same era of Kay the colors are indeed accurate!

    Warbird Projects of mine

    Well folks a very VERY special picture of Special Kay turned up today! This is Special Kay in 1978, making her first flight since her massive 1977 landing wreck. She was landed with the gear up, tore off both engines and the engine nacelles, plus causing a bunch of other damage. You can actually...
