[Fot] Anti Runon Valve ADU9535

[Larry Young]

I've got the idle as low as it will go at about 1,000.  I think I might 
get it down to 800 with some carb work, but in the past it would still 
occur at 800.  I have removed the vacuum retard, which helps the idle.  
I've been letting the clutch out to kill it for the past 25 years and 
would like to fix the problem rather than continue to work around it. I 
was hoping a carbon free engine after the rebuild would cure it, but it 
didn't.  I don't fully understand the later TR6 setup, but I've heard it 
requires special carbs and was tied into the charcoal canister.  The 
ADU9535 seems like the simplest way to go for a retro fit, since it 
could be tied into the brake booster line.  Ed, if you've got one I'll 
be glad to take it off your hands.
