Viking Steel Bungee Install question


I installed the viking spring system tonight, but had some trouble adjusting it and would like some feedback.  How stiff should the nose wheel be after adjusting tension with the side nuts?   

The reason I ask is that i've got mine bottomed out and it still doesn't seem stiff enough to keep the nose gear from hitting the stops on landing.  I can push the nose by hand and see an inch or two of travel.  It seems like the momentum of the engine on landing would easily cause the nose gear tube to hit either the welded stop ring, or the aluminum spring cap on top.  

As you can see from the pictures, it's cranked way down there.  If i had the nuts back where others seem to have them, the nose would sit a full inch lower because of the light spring pressure.  

Admittedly, I'm comparing it to the rubber bungee cord that used to be on there.  That was so stiff, i could stand on the engine and the strut would barely move.

Jan at Viking has been very helpful. The corvair is one of the heavier options and puts the cg at the very front of the limits with me and full fuel. I adjusted the spring to look more like the images I've seen and tested it today. There was not excessive bounce either when taxiing or landing.

Actually the Corvair engine it quite heavy, please check that weight on the nosewheel by putting a balance under the wheel. The spring could be switched for a
heavier grade. I'm looking into this already.

how much weight is there on your nosewheel ???? If your nosewheel is very heavy it may compress the spring before it even start absorbing shocks. I will check mine soon and let you know.
