I have a allis c that won"t start and i put new points in it and a condenser. when I try to start it i put the throtle back and it starts popping like it wants to start but then I put it back some more and it quits trying. I was going to try to put a new coil and maybe a rotor in my magneto but i thought i would ask here first in case anybody else has a suggestion. It is my first time on a allis gas I am more of a John deere diesel person myself so the help is greatly appriciated.
Thanks
 
I was also going to add i cleaned my carburetor and I don't know maybe it is something with that?
 
Mags can be fun to trouble shoot plus if you got the rotor in wrong then you have another problem. Drop me an e-mail and I'll send you a manual for the mag which might help you figure out your problems. Also did you check to make sure you have a good blue/white spark and true copper wire plug wires?? Also do you here the impulse trip when you turn the engine over??

First, will it start if you pull it ? Second, have you tried starting with the throttle almost closed and the choke on? Is there a strong blue-white spark that will jump a 1/4 to 3/8 inch gap? Wrong or right I try to concentrate on one thing; gas OR spark, and when that is correct then I know that the other is the problem.
 
Like you just said run one problem all the way before you jump to the other. goes for many other things besides an engine.
Just started a Allis B that had not run in years.
First check was spark. It had none. Pulled the magneto wires with the plugs removed and placed in each wire. I then clamped it in the vice. Pulled the cover off and checked point gap and cleaned the points. Every thing was dry and looked like new. I put the cover back on and snapped the magneto over holding number one plug to the case. I snapped it until I had spark on the nomber one plug. I then changed to the next plug and had a good strong spark. I snapped it over checking each plug one at a time three or four times. Made sure number one plug would be the next to fire, set the tractor so number one started to have compression and replaced the magneto.
Cranked the engine over and nothing. Sprayed in some started fluid and had a rumble.
I then removed the gas line at the carb and had good floe. took th eplug out of the bottom of the carb and just a dribble and then none. I removed the carb and started to clean it. I couldn't get the feed tube or the power jet out without heat. Running a small drill bit down the hole the feed tube goes I was able to get brown sticky crud. Same thing when I put the drill in where the power jet screws in. (that area must be clean and have a small puddle of gas for an easy start) When the cleaned carb was replaced I had good flow out the bottom of the carb.
Walla fire in the hole.
In not tracing a problem all the way can leave you one check from the cause of the problem.
In reading the posts of peoples ideas can cause a person to jump back and forth. Just resist and stay on one side. Most all posts are good advise in places to look but when you start on one side it will be quicker to on that side untill you are sure every thing has been checked before moving to the other side.
