I'm having a major difficulty with the new ignition you sol me for the 45 IRS. According to your instructions "Vlach to ICU conversion Electronic ignition (for 2S LiPo). The ignition has the boot cap for14mm Brisk spark plugs with the Vlach type shielded boot. This ignition can be used to update old Vlach equipped engines to the new ICU ignitions." The problem I have is that the boot on the ignition I received doesn't does not fit either the Brisk plug or the Champion R6J6 original plug. The boot silicone sleeve is too large to hold these plugs.

I'm including photos to illustrate what's happening. On photo 1 you can see both the old RCexel ignition and the new MSR ignitions. Note the booth on the MSR ignition doesn't reassemble the booth shown on the Instruction Manual. This boot doesn't even have the ground wire shown on the manual photo.

On photos 2 and 3 you can see both plugs don't fit the MSR booth, and on photo 4 you can see the obvious difference in internal diameter between both booths. Am I missing something here? Please let me know what's wrong with this picture.
