<VV> Turbo Carb

 The YH is adequate, if stock is what you're looking for. Doesn't cut out in the turns, idles well, generally good driveability. But it is THE performance limiting item on a turbo engine. I bored mine, worked a bit better, but the 2" SU made a HUGE difference!

Hey, isn't this a hobby?  The YH can be made to provide satisfying 

response/performance if you spend a little time understanding how it works, do 

some investigative work, and do cause-and effect troubleshooting.  You can be 

"ZEN" with it. Some of you motorcycle tinkerers will understand!   

The Blackhawk rods/jets, new gaskets, accel pump, ball-type float valve, nice 

clean carb, unrestricted fuel return line, fuel pressure regulator, the manual 

from Carter, Clarks tech tips, and the wide experiences of this forum are all 

"tools" you should be aware of.  It's what keeps me interested in my 'Vair.  Go 

fix'em and drive!

defeatest and misleading at the least.  Sure there are several better carbs.  

Get a yh right and it will allow your low compression turbo to idle with the 

best 95 twin carb for a half hr at a stretch without loading up.  Open the 

throttle and it will pass a surprising amouut of controled fuel air mixture for 

the size of its venturi.  Educated tinkering with its metering rods can give a 

smooth flow of power from idle to over 5000 rpm with no problem.  The fact that 

it limits ultimate engine output was planned by the engineers to save the engine 

from destruction by the owner.  The 150 carb is more conservative than the 

bigger 180 of course.  Even a high output turbo can't pull enough air through a 

180 carb to make a beast out of the engine.  Good performance is about all you 

can hope for, with emphisis on "good", not exceptional. 

> I am defensive about the Generals economical choice of a carb for the turbo.  

It does a good job for what he spent for it.  If you say it is a POS then you 

better come armed with some facts.  I mean other than you aren't mechanic enough 

to make it work as designed.    Smitty
