Need help Anyone experienced with Weber carbs & methanol…?
I have a few question about weber carbs tuning for my car.
Im using Honda civic 1400cc sohc , 14 : 1 compression ,it was for drag racing use.
It breathe with four barel weber 45mm carbs.
On weber manual guide, they said that the starting poin to tune this weber with gasoline was like this :
-Main Jet Size = Chooke X 4
-Air Jet Size = Main jets + 50
Now after a few optimizing tune from that starting point calc , I found that the best setup for my car was 38mm choke ,145 main jet , 175 air jet and F-11 emulsion (I ran 110 octane race-gas) .
Now I want to try with methanol , people says that we must run much richer with this methanol ,because methanol will burn at 5-6 : 1 air/fuel ratio .
But I don’t know how is the starting point to use for the Main, Air Jets size or the Emulsion tubes to uses with these methanol.
Please give me a suggestion about this
Thanks
