Nice and informative thread
But have questions regarding 4 stroke 78 cc engine
i have made a video .. it is 15 minutes i think but hell it is in twi parts 7 minutes each i think but the size is very large ,, always get error during youtube upload,, will make some more videos,,
Moving the Fuel screw clockwise wud decrease the fuel supply...Moving it anti clockwise wud increase it.. as mentioned above.Tuning a bike wid bad or irregular current supply is a big problem so better nt screw it up... try tuning it after the current problem is ensured to be Ok.
Not much difference on milage... Incresing the Rpm too much wud result in a lillte uselessly hot engine, and wud basically spoil ur engine oil before time. otherwise Rpm is a relatively harmless thing to adjust...Increase the rpm to the desirable limit where u bike doesnt stalls (turns Off) whle idling...
the small screw is for fuel adjustment. Bigger is for RPM
^^ wrong bro
actually that screw controls air not fuel and by usin air it controls fuel.. in a way u r rite but its again a bit tricky issue
According to the article posted above all 4 strokes control fuel, not air!
2stroke machines have an Air screw and 4 stroke machines have a Fuel screw. I hope you note this VERY well. Air screw is located on the carb away from the engine.Im sure Yamaha royal that i had, used to have an air screw... as its fuel was adjusted thru its drums and needle valve setting... thts probably the reason once mishandled royal always gets over and drips fuel out even when standing turned off....
Bump! For a helpful thread!

bro honda pridor ka bas aek he screw ha carb pa golden colour ka with a needle attached to it and a small spring and i cant find any other screw any ideas?????????
post the pictures of your carb from all sides .. hope there will be something..
Bro steal it from your friend's mechanic :o someone i knew did it once :thumbdown:
I also have a Honda CD 100. Its fuel adjustment screw is placed behind the utility box. All you need to do to reveal it for adjustment is: open utility box cover with key, find and remove a rubber washer in the area of utility box which is in-line with carburetor, you will see the fuel adjusemtn screw through the hole in utility box.
