850 Ultra XP lean bogs when secondaries open

there is many reason why one eng won't stumble and another one will.

Mine reared it ugly head when i when from a 3000 stall converter, that had next to nothing for resistance below 2200 rpm. Too, a 4200 stall converter that had the same load or resistance, on the eng, at 1500 rpm that the 3000 stall convert had at 2200 rpm.

Hope that made sence.....................

Even thought it stalled at a much higher stall it put a load on the eng at a much lower rpm and caused the bog that i struggled with for 2 years.
The carb didn't change, only the conditions.
The 850 demon, never even as much as a wispier of a bog until the new converter was installed. Which stalled Higher.:realcrazy:
