William Robison -> RE: Saito 82AA help needed (11/17/2004 9:08:05 PM)

Zork:
You say relatively new, if that means 30-60 minutes total time it's a little soon to expect a good idle.
Newness notwithstanding, the early FA-82 had a back plate known to flex, allowing the inlet tube to come slightly unseated in the head, giving an air leak. Also, the early ones had only the o-ring to seal the pipe, without any support. Both these things can lead to an intake air leak, sounds to me like that's your problem.
Pull the two screws holding the carb, slide the pipe out, find a small washer to support the o-ring. When you reinstall the carb and intake leave the screws loose, slide a strip of paper against the screws from the bottom, then tighten them. This strip of paper will press the carb and intake a little tighter into the engine.
If you can't find a suitable washer, the carb gasket set from Saito/Horizon includes one.
Picture attached of the intake pipe.
Hope this helps.
Bill.
