carb size calculator

8rpm? that's a really slow engine you have there...
try 8000rpm

Sure with 8000 RPM it shows 24 mm carb!

But if he wants 8 RPM engine he needs 0,75 mm carb

when i put this values on the program:
rpm=8000,stroke=43,bore=47.6,gas speed=45
the engine displacement is =7651.9699872 and the carb size is=240.280922008972....
so,were is my mistake?did i made something wrong? what should be my right carb size?

You do something wrong, (maybe you wrote to much 0 or write the , on a wrong place) cause if I fill the fields with your datas it gives: 76,51 cc and 24,028 mm carb.

I'll have to write it again. I'll post it in around 8 hours

or scan my hard disk for it.
