<VV> re: heavy carbon buildup

[djtcz at comcast.net]

Around 1970 I bought a 66 corsa turbo (mileage not recalled) that I bought with a puffing head gasket, that I had repaired by a Chevy dealer.  A little later that motor came out to be HotRodded by me for use in another car.

During the autopsy I found heavy, port filling carbon deposits on the backsides (port side) of many of the (intake?) valves.  I believe I briefly speculated that perhaps the abuse that had taken out the cylinder head gasket had also toasted the valve seals before putting the heads in the spares department, as the project's 140 heads were being prepped for use with the turbo innards.

Any heads I use now I investigate (measure!) the valve stem and guide condition closely.

I might still have those heads someplace.

Greetings all,

     I am preparing to rebuild my (140) carbs with the help of a friend who has some experience.  I found that there was heavy 
carbon buildup in my engine (which had a very low mileage rebuild and was not 
burning oil) so I'm wondering if you guys could point me toward the known 
trouble spots etc.  I'm just looking for a little advice as to what to look for 
and fix that might be particular to Corvairs.  

     I had been planning to get my carbs professionally rebuilt, but I spent a 
lot more $$ then I expected on other parts of the car (heads) and now have to 
watch my budget.  

Thanks!

Ray Rodriguez
