I was told by a friend mechanic who only gives me advice, to adjust the idler screws on the carb. However I am not sure how many times to turn the screw. I am not getting gas into the cylinder and he said this might be the problem. Also could it be a connection between the carb and the cylinder? hoping to get this running soon with help from my fellow forum runners! (as i call them)
once again it is a 1968 4 horsepower ted williams, 2 cycle aircooled motor.

Any information for would very helpful, Thank you!
 
That carb is probably not the emissions carb that most of have so I will try and post from the book,

CARBURETOR ADJUSTMENTS
IDLE SPEED ADJUSTMENT​
This screw is located on top of the carburetor and
contacts the throttle. To pre-set the idle speed, back
out the screw, then turn in until the screw just touches
the throttle lever. Finally, turn the screw in one (1)
turn. Once the engine is running and brought up to
operating temperature (3-5 minutes), the final idle R.P.M.
can be adjusted with the aid of a tachometer.​
FLOAT TYPE-FIXED MAIN, IDLE ADJUST​
Turn the mixture adjusting screw in (clockwise) finger
tight, then one (1) turn out (counterclockwise). This
setting is approximate and will be enough to allow
the engine to start so that final carburetor adjustments
can be made. Start the engine and allow it to warmup
for approximately 5 minutes.​

Do not adjust the
carburetor with the engine cold.
NOTE: If the engine falters or stops after the choke
lever is moved to the "OFF" position, open the mixture
adjusting screw 1/4 turn counterclockwise and restart
the engine.
With the engine running, place the speed control in
the "slow" position. Turn the mixture adjusting screw
clockwise until the engine starts to falter, remember
this location. Next turn the screw counterclockwise
until the engine start to sputter or drops in R.P.M.,
remember this location. Now turn the screw clockwise
until it is halfway between these two locations. This​

will be the optimum carburetor setting.
 
you wouldn't want me, I would just drink up all your beer and then start blabbering about my general disgust with politics.....
 
lol well i happened to get it to run today. I was amazed that after 20 years of sitting up, this thing ran. not very well at first but im working with it.
 
well after a little digging, i found that this motor indeed is a water cooled, glad i started it in water, however it would seem that the impeller needs replacing, the water has small rubber shavings and pieces in it, im guessing thats the bad impeller?? maybe the seals?
any ideas where i can get a new impeller? i know they are pretty common, i just dont know where to get one for this year and model.
