OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Is 7.20 a good reading on old Victa Mayfair coil?

As luck would have it, I found an old EI module in the dark recesses of the shed. Not sure when or where I picked it up, but I tested it and it is still good. One thing they never tell us in the instructions STEN provide is what to do with the earth wire on the existing coil. Do you just leave it in place, i.e. earthed? That is what I would presume, but just thought I should ask first.

Also, what is a suitable modern replacement coil for Victa 5-183? I assume this translates as MA05183A. Told this is discontinued, but am betting there will be an aftermarket replacement that will fit?
