My wife and I took our Twin Javelins out to a local benefit Poker Run over the weekend, they ran beautifully.
While doing a post run clean-up today, I noticed that one engine had produced about twice as much unburned fuel during the 2 hr variable speed run. The larger volume was also more turbid and different color as shown in the pic.
I quickly checked the HS needle just now on the port motor, and it seems reasonable at 1/4 turn out.
-First run of the season, so had done a little carb dialing to individual engines (other one shut down during tweaking) in-water, on the way out to the start for both High & Low speeds.
-Both engines had fresh gas/oil mix. (Shell Nautilus oil)
-The boat made 25mph WOT (non GPS) and felt good and sounded better!.
- We don't have a lot of run-time on this rig, as I just re-launched it last season after extensive preservation efforts.
- Haven't got my compression gauge with me, but both plugs look decent.
- I have little digital tach's on both engines, but their info. is all over the place and not useful at this time.
Before I delve any further into the situation, I thought I would share my findings, and see if any you guys had any ideas?
