Walt GiffordParticipant
Nope.
Walt GiffordParticipantI would sell that engine and get you a Briggs LO206.

Walt GiffordParticipantYou want the arm to be slightly above the channel. You have to bend the arm. if the arm is too low it will restrict fuel flow. Set the arm first then do the pop off.
Pop off, low pop will not hurt you, pop that is too high will restrict fuel flow. If you find you’re sluggish coming off of tight turns and can’t seem to dial it out with the needles you would try a higher pop off.

Walt GiffordParticipantI’ve seen them plugged with carved aluminum blocks. RTV sounds like red neck engineering. You can run for fun without a power valve. If it’s not fast at least it’ll be loud.

Walt GiffordParticipantSteve, saw the ad. Do you race at nicholson?
Walt GiffordParticipantJust take it apart and see what broke.
Walt GiffordParticipantJames, you’ve got PM.
Walt GiffordParticipantThe top gasket can be had at most small engine repair places. I like the cork ones, the rubber ones seem to shrink and I’ve made ones out of gasket paper that leak pretty good. Check for cracks in the plastic cap right under the fuel nipple. I would leave the needle seat in there. All this time in karting I don’t think I ever pulled one out.

Walt GiffordParticipantYes, it’s for a Yamaha KT100 or any piston port engine.

I wouldn’t be too concerned about the ackerman effect of the steering arms as long as it’s the same on both sides. Most of the ackerman effect is caused by the pitman arm on the steering column anyway. Ackerman sets a different radius for each wheel but it’s main function is to help make a height difference on the front wheels which can mostly be dialed in with caster. I’ve never heard of anyone tuning with ackerman and I would bet all modern aftermarket spindles would be pretty darn close to what you had before.

Walt GiffordParticipantIs that real carbon fiber for $349? Must be just one thin layer. Says it’s 48 ounces. Probably be allot lighter if you sand that thick clear coat off of it.
Gif
Walt GiffordParticipantSeems like when you have a set of scales set up level in the pits everyone comes around and wants to use them though. How do you check if the front and rear axles are parallel on the stand?
Gif
Walt GiffordParticipantBreak even point is 3 Qts.
Walt GiffordParticipantYou have to check your pop off pressure and fulcrum arm height. There is a way to set up that carb so your engine will idle and still run good on the track. If your carb is set that way you’re going to need needle settings that are very different than conventional wisdom.
If you can’t get going coming off the grid is it too rich or too lean? If you choke the airbox does it pick up or get worse.
Gif
Walt GiffordParticipantWell, if there’s some slack and you tighten with the wheel hanging down then you could hit a bump on the track and knock the slack up the other way. If the wheels on the ground when you tighten things then you hit that same bump your set up is not going to move. Probably doesn’t matter too much in todays modern world, just a habit left over from the old days.
Gif
Walt GiffordParticipantIt’s nice to have everything sprung the right way when you tighten things down.
Walt GiffordParticipantMe Too. Is there a way to check PM without the link?
Walt GiffordParticipantI always do my set ups under load.
Walt GiffordParticipantIs that a steel nytro that’s been cut open to run as a dry clutch? I didn’t think the wet clutch friction disks could take the heat without coolant.

Walt GiffordParticipantHorstman DXL 3 disk 4 spring.

Walt GiffordParticipantTighten the outer bearings first with the axle in place. Use a yard stick across the bottom of the frame and measure from the bottom of the axle to the top of the yard stick (bottom of the frame) to get axle straight with the frame. Then tighten the third middle bearing. If it tightens up after tightening the third bearing drill the mounting holes in the bearing hanger bigger and try again. Are you sure the axle is not bent?

Walt GiffordParticipantThey make brake grease that helps it retract easy.
