i broke my pullstart to last friday and it was the spring to
i fixed it with another spring from another brand but i don't know if it will hold up
i also noticed that sometimes (this was a couple weeks ago) the pullstart would't return after i pulled it, first i tought the spring but that was not the case (then)
so i took the rear off the savy and started to investigate
when the pulstart was blocked and i would hit it with the back off a screwdriver it would return
strange
when it took it off the engine and into my hand i could pull it a 1000 times without stopping
BUT suddenly it stopped
then i saw that the "thing" where the cord rols onto came out and "jumped" over one off the 2 copper screws that are there to keep it on his place
so there was play on it but how could i solve it????
after thinking on this problem for about an hour suddenly it hit me
why not shim the "rolling" thing a little backwards??????
(a little more deeper into the housing off the pullstart)
so i searched and searched until i found those shims i used to shim my diffs (kyosho ones) and they fitted perfectly over the notch that is 13 mm
i used 3 off them and since then it worked fine
until last friday when the spring snapped that is
