Basic info. 83 fj60 no smog, weber 32/36DFEV (PO put on)
i have set the lean best idle according to man. specs.
Okay, Today i took my "brick" as my son calls it for a high speed test got up to 75. yeah me. problem was that when i started to climb the hill i just went down at 75, and the carb loaded as gravity and reality brought the "brick" back down to 60 the truck almost stalled between 2200 and 2800 rpm in 4th. once the rpms got back to around 2100 it was fine and climbed the hill albeit alittle slower.
why the rpm cut out under load. it accelerates fine in first and second and the stumble now reappears in third in the same rpm range, if you slow down or shift engine is smooth again.
any help is greatly appreciated.
Thanks
Dan
