a case 4 kate
New User
New to the forum and need advice. Thanks in advance. Case tractor acquired in 1977 used, NO SERIAL # was told it was a 1959 511b industrial. Have since learned 511b is ag. It could be a '58 or '59 510b with a 31 loader or maybe a '60 530? I don't know if this really matters. Tractor is 4cyl gas 4-gears low, 4 gears high, has a shuttle shift. In 4th gear high (8th gear) I cannot make the smallest hill going down the road and cannot get speed over about 10mph even going downhill. Cannot get rpms up. Used to go down the road good at around 20-22mph. Now, I see some smoke, acts like running rich, has even coughed / chugged and stopped. Starts right up again. Starts and runs good in ALL other circumstances. Have had carb and gov. checked by 2 independent, qualified mechs and told both are ok. Problem started around the time I had dist. replaced with electronic ig. Could this be cause? Also, have always run trans / hyd fluid in transmission - is this ok? Please help if you can.
