I replace my starter spring every winter. When I do so the old one is shot. They just don't last long plus its a good piece of mind. Not hard to do if your able to remove and install the starter without a big hassle. I wouldn't think it has much to do with engine kicking back. I run 39 degrees without any retard or start assistance. It only kicks back once in a while.

thanks for the reply. has anyone played around with a digital advance curve? say a little less timing at torque peak and maybe another 6 degrees while on the stop and say 3 or 4 degrees at the top end over best torque peak timing? be interesting to try. would definitely show a little leaner on the stop with more timing although you would have to close the throttle a little more. definitely more efficient. i think a few degrees more on the top would help too.

Keep in mind every change in t-stop setting changes where this timing change would take place But please try and let me know how it works
