SO...ARE THE TWO SPRINGS REDUNDANT?
i asumed they "held up the weight" to prevent the ios's getting squashed, basicly keeping the rubbers central.?
Hmmm, feedback when I asked this question was inconclusive.
My conclusion was that it may be advantageous to the iso rubbers on a stock electric start engine unit.
Mine is not elec start and with the belt drive and light clutch the engine unit is probably 10lbs light than stock, and much more so compared to a stock electric start unit.
So I went without the springs and it feels great!
The springs don't look good to my eye though, they basically put the engine under constant tension they are trying to pull the engine up by the head after all. That looks to me to put stresses on the barrel base and crank cases.
All IMHO of course.
