My Ford 850 has a 6v system. I was having trouble getting it to start cold or hot and with it running rough when hot. I put a new ignition switch on it less than year ago.
I noticed that the spark at the points was occurring only intermittently so I replaced the points and condenser with a Pertronix ignition system and "flamethrower coil". The electronic ignition seems to have improved the cold start and the smoothness of running when hot. Starting when hot is still an issue. It usually needs to cool an hour or two before it wants to start easily
The addition of electronic ignition also seems to make the tractor more sensitive to the choke. I used to crank it a few seconds with full choke, then without choke then with the choke again. Now it seems like it wants to start just as I release choke. While going through that start process, the tractor never seems to give a warning that it's ready to start (like coughing or sputtering) right up to the second it actually starts suddenly.
Two questions:
1) What should I check next to help it start more easily
2) Is there a specific procedure or sequence I should try on the start. i.e 1/4 throttle, a few revs without choke, then choke for a few revs etc.
I thought saw a starting procedure on this forum specifically for this tractor but I can't seem to locate it again. Maybe I saw it as a general procedure not specific to this Ford? Thanks
