Also, the use of Locktite 221 is specified for this part in the 912 Illustrated Parts Catalog.

The engine starts fine right away and has about 2 hours of taxi time on the engine. I get 5050 rpm at wide open throttle and the airport is at ~5000'. The weather here is in the 90+range shortly after 9:00 am. The problem I am having, which has kept me on the ground, is the mag drop. It is about 650 rpm on each ignition and they both run rough. They are close together but that much of a rpm drop seems very unusual. The exhaust pipe is sooted which suggests it is running rich. The plugs also are very black and cleaning them has no effect. All the other temperatures look normal. I tried a five minute run at full throttle and that had no effect either. Any ideas where to look next will be greatly appreciated.

The good thing is they are almost equal. What rpm are you doing the mag drop at? What is the plug gap? It should be between .023 and .027. Better to be the wider gap for the summer months. Are you running an electric pump with the mechanical all the time? Have you synced these carbs? Did you put a fuel re-circulation line in during the build. The new pumps really need one. Where did you mount the carb vent tubes? These carbs almost sound like they are flooding, but we could use a little more info. It is possible you have a wire connected wrong. -------- Roger Lee Tucson, Az. Light Sport Repairman - Maintenance Rated Rotax Repair Center - Heavy Maint.
