I got help on my gas mixture when my exhaust manifold got red and, it was timing. Now I need help on setting the timing so I have the correct retard and advance. The timing was my problem on heating and I adjusted the rod but not sure of the correct setting. I will probable be back with a carburetor problem as the T runs great at an idle but when I go to half throttle it runs great for about 30- 45 seconds then stops like the key was shut off with no sputter or anything. After about a minute and a couple of cranks it runs great again except when I increase the throttle.
Thanks , Don
Timing largely depends on which commutator you are using but rule of thumb on most roller/brush timers is to have the spark rod at full retard and the timer rod should be set near 2 & 1/2" from center of timer rod at timer to center of bolt holding the timer spring clamp onto the engine.
Fuel issue could be float height set too low or debris in the needle & seat constricting flow.
The fuel issue could also be not enough fuel flow at higher engine speeds when more fuel is needed than when at idle.
Disconnect the fuel line at the carb. and let the fuel run into a container. How fast does the gas run out? It may be as simple as dirt in the vent hole in the gas cap, or the screen in the gas tank sediment bowl being plugged.
Sir,The mixture adjustment was made to be used and not set in one place!! Bud.
Don, set the spark lever all the way up, pull #1 spark plug and then put the wire back on it while the plug rests on the cylinder head. Turn the switch on to battery and crank the motor over slowly by hand watching the position of the piston. The plug should start to fire just a tad past top dead center with the spark lever set all the way up on the quadrant ( it may not spark the first time the piston comes up so crank it up again if the plug does not fire the first time the piston comes up). If the plug does not fire at the right time disconnect the rod to the commutator and move the commutator until the plug fires right after top dead center and then adjust the commutator rod so it fits into the commutator with the lever all the way up on the quadrant being careful not to move the commutator. Once you have that right you will be able to adjust the timing as you drive by advancing the spark as you pull down on the lever. Every car has a "sweet spot" on the quadrant where it is running at its best and you just have to drive and play with the timing to figure out where it is. Just keep advancing the spark slowly until it runs best at an idle and then when you are driving at about 25mph. You have to play with it but once you find the right position you can even mark the quadrant with a little nail polish or something else for future reference.
You can also determine the timing by the relative position of the crank when a coil buzzez. When the crank is streight up so is a piston. If the buzz is too early ie before the crank is streight up with full retard the rod will have to be extended until it buzzez just past over center. Be carefull!!!!
