Re: spark test Q

Get an open air gap tester and set it to 7/16". Stay away from the neon ones.

inline is the only kind the auto parts store carry as far as I can see

Re: spark test Q

Stevens instrument Company sells the ones reccomended by Evinrude. I believe its the S-94 or something. I would bet that you could buy one on this website and help support the forums.

Staple a couple of pieces of wire on a piece of plywood.-------Set up a gap of 7/16" between the ends.-----Stick one end on the block with an aligator clap and the other end into a plug wire.

Re: spark test Q

Take some jumper wires and ground them out one at a time. Use the tester on one wire at a time.

Re: spark test Q

I grew up in FT. Myers but im not understanding what you mean by ground them out. shud I have all plugs pulled out?

Re: spark test Q

Pull out plugs. Disconnect the plug wires from them. Then ground out three plug wires and check the spark on the remaining one. Do the same to the remaining other three. OR !! Leave the plugs in and pull the wires off so motor doesn't start. Then check the spark on each wire one at a time.
