ethanol will damage some rubber's and some plastic's but these are easily replaceable. every thing else is unchanged except the carb. you need to richen up the carb as you will run about 1.6 times more alcohol than gas.some of the things you will need to replace are
1: rubber fuel lines. there are alcohol resistant lines available. check with your local speed shop.
2: fuel filters with plastic housings and elements. there are good aftermarket units with sintered metal filters. just remember to keep them clean or else you will lose fuel flow more rapidly than usual.
3: the needle and seat in the carb. viton is not designed for alcohol. replace it with a steel needle and seat. they are available for most carbs. again check the local speed shop.
4: you can run a little more timing than with gas as alcohol burns colder than gas. as a side benefit it will be easier to pass emissions as the sensors do not read the exhaust gasses as again alcohol burns colder than gas.(tip here for you gas guys if you have to pass emissions and aare having trouble, run your tank down to 1/4 full and dump in about 5 gallons of alcohol then full the tank and drive to the emission station for testing. you should pass with flying colors.)
if you dont want to go through the hassle of rejeting your caarb, you can get one already done from barry grant and others. you might find starting the car on a cold morning harder than with gas, and you will need to run a fuel additive to prevent gas line freeze. also remember that alcohol is hydroscopic. that means is absorbes water. gas does not. just be aware of these items and you shhould have no problems. |
