Ok if this carb was built for Alcohol then it will never run right with E-85.


It is not possible once it is made for Alcohol to change it back to E-85, everything will be to big now in side the carb.


It will have the wrong needle and seats in it to start with as they are to big .150 or bigger and the needle are made of titanium. This means you can only idle with low fuel pressure, this is why fuel would be coming out of the vent tubes.

Never put rubber hose on the vent tubes or join them togather as it will make problem in side the fuel bowls limiting the amount of fuel the motor gets in the upper rpm.

It would be possible to use this carb with E-98 which is almost pure ethanol, but you will need to get a mechanische Pumpe to make it run right.

Hope this helps Tony

Tony,

this carb was bought as Alky carb and rebuild by Mark Sullens for E85.....................

Fact is, it was a decision between a Pro Systems rebuild but after speaking with at least a dozen of his E85 customers from that SPeedtalk forum which were not so happy and also speaking to Mark's customers which all have been quite happy with his setup and service Jeff and me decided to give him a try. SO yes, I did my home work upfront.

Just because Pro Systems carried big words in that arguments which helped nobody did not make him better in any way. I am in contact with Mark as we speak and his knowledge is simply superb. Fact is, all of Marks setups are faster then Pro Systems, so just having a big name is just half the game

right now we are verifying logs and tracking numbers, not that I did received the wrong carb back and somebody else has the carb destined for Ralf.
