Manco 706b

[H-Hefley]

I bought a real clean restored manco 706b as a Christmas present for my kids, I wasn’t able to test drive it prior to purchasing due to the location. Come to find out at 10-15 mph the kart has severe death wobble, everything is tight and nothing appears to be bent. The tires are slightly toe’d in - does anyone have any suggestions??

fix the toe to a neutral position by adjusting (shortening) the tie rods.
minor toe out is better than in.. neutral (under load) is recommended really.
Ideally adjust the tie rod length under load.. makes things easier.

Also make sure the coilovers are relatively firm and the steering linkages aren't worn out.
(IIRC pressed sheet knuckles they might be not as they should be by now)

you want round profile front tyres for a single A-Arm suspension.. 145/70x6 is what it had.
(can't tell what's installed form the pic)

death wobble is always a sign of some worn part..
tie rod knuckles, spindle bearings, wheel bearings a worn kingpin itself maybe..
Essentially every moving (rotating) part
between the plastic steering wheel and the rubber tyre should be double checked.
And since it has front suspension, the a-arm bushings and shocks,
shocks should be firm but most importantly identical.

My first kart had death wobble around 35 because of the original tie rods
