hi to all,
mi 1914 touring is not running smooth.
i changed the spark plugs, new coils and adjustet the timing. what else it could be. the timer is a new day timer with brush (this is the only thing that i did not change yet)

Clean or replace your sparkplugs....Basics first...
Are all the connections on the coil box tight along with other electrical connections ? What about gas flow and condition of gas.
I have New Day Timers on my cars. I did replace the brush with a new one and it runs fine. Also is the surface in the timer smooth? I resurfaced one of mine and the performance is fine and my 21 runs smooth.
I did have an intermittent miss in my 24 Coupe that drove me crazy till I checked all the coil box wiring and found a slightly loose nut on No.3. I tightened it up and all is well. I spent hours checking and removing this and that when all I had to do was to tighten that nut!
spark plugs are new
wiring checked and they are ok
Maybe the carb adjustment? Did you try shorting out the plugs to determine if it's in one cylinder? If it's not a clear miss and it's running uneven or seems sluggish try the Carb adjustment moving it rich to lean and so on.
If that's not it it could be the timer brush spring is weak and not making steady contact. I bought the brush that Snyders sells and it works fine.
i changed the mixture but it not runs realy better.
Check your timer and wipe it out. Make sure it's smooth inside.
Check to be sure that your intake manifold gaskets are not leaking.
Have you checked the Magneto contact on top of the transmission cover?
I don't have early T's but my 1919 Runabout was running a little rough for a while until it finally died. It started OK and ran OK on battery. It always ran OK on mag but this time it started running rough and wouldn't hardly run. After I got home I found there was a small amount of lint under the contact. If you check the mag contact make sure the spring is making a good contact and is centered on top of the lead button on the mag ring.
Hope this helps.
John K. inadvertently brings up a very good point. Whether the car runs rough on magneto but ok on battery, or visa versa, or, if it runs rough on BOTH magneto AND battery, this can be a help in chasing down the problem. In other words, whether it's carburetor/fuel problems or ignition problems,....FWIW,....harold
Check the timer that you haven't changed yet. Maybe dirty, maybe brush is worn, maybe floppy in there. Give it a good going over. Kinda like Hal said!
i go to check the timer and then we will see
