Being that CH has been lax in ignition deliveries, Tim, I modified mine with a pair of (GASP!!!) Da plug caps. Work just fine. I have two ignitions set up for the new 110's. It's a pity such a great engine is limited on deliveries because another company can't get its butt in gear. The ignitions have been on order for aobut 4-5 months now. . guess that says a lot about CH's priorities.
