[Roadsters] What is in todays fuel that makes everything gum up?

[Keith0alan at aol.com]

The problem with E-85 and carbs is the effects of the alcohol on the  
aluminum. As long as the jets are available a regular carb can be jetted for  
E-85. Once jetted for E-85 it will be stupid rich if you put regular gas into  
it. I have considered setting up a pair of SUs for E-85 but that is another  
project I have not found time for. It should be simply a needle change or  
possible nozzle and needle. This could be a good choice for some of the 
stroker  configurations that have quite high compression as the octane rating of 
E-85 is  over 100. 
 
    All that said, for some odd reason it is illegal to  convert a gas car 
to E-85 for street use. Seems fairly silly to me.

Dave,

My understanding is that E85 and Gasoline are so  different in their 
requirements that the only way to  use  them  on the same engine is to go 
with FI. I don't think I've ever heard of a  carburetted engine being set 
for E85 even though there are some E75 carbs  listed on the net.

Peace,
Pat
