Problem fixed: skip at top end speed

I noticed a weak orange spark when you should have a bright blue spark. So I knew it could be the stator or trigger or switch box. You are better off to replace all 3 at one time which I did. Problem solved. I have used Crowley several times and I knew they were great people to deal with.

Everything was great except the shipping. The order came by a combination of carriers, culminating with USPS. There is at least a day's delay in getting from the initial carrier, through the PO and to me and tracking the package is difficult. I would like a slightly higher shipping charge for a faster, single carrier (including USPS Priority) method.
