I recently purchased a secondhand 4hp 1979 Evinrude Motor (49B36D - I think its a European model). When I bought the motor it wasn't working - but soon started after a good carb clean.
Today I decided to replace the HT leads (even though it was working fine) as one of them had been patched halfway down. Now, I am only getting spark at one of the plugs. Initially, I thought it must be a problem with the new lead, but am still getting a problem when I swapped back to the old lead. I have swapped the coils - and both are working - giving a good spark on the other lead. I have tried swapping the same condensors - with the same effect. I have cleaned the points in case I got some dirt in there. The points are the only part of the setup I've not swapped over and I'm now beginning to struggle!! Please tell me I'm missing something simple. All help and advice very much appreciated! Why did I not just leave the working dodgy setup well alone!
