I will thank you. I just bought this about two months ago and now i figure a total rebuild would not be a bad thing then i know what has been done to it. Thanks everone for yor help
update i checked the pcv vavle and hose, checked pushrods and rockers. compressionn test 1-110, 3-65, 5-70, 7- 80, 2-65, 4-60, 6-65, 8-65. Think i have came to the conclusion of pulling the motor and start going through it.
Installed new distributor running great now. Have a few spare parts now that I was replacing while chasing the problem. Thanks to everyone for the help.
1974 cj5 304 hard start replaced rotor cap plug wires still starts hard once it gets hot. Checked timing several times. But while setting the timing I cocked the cap very slightly and motor smoothed out. Then shut the motor off and held the cap over and it started right up? So now I am pulling...
