Just had the valves adjusted by my mechanic. After doing so, the car did not idle well when coming to a stop. Would drop to about 500 rpm. Went back to the mechanic, he adjusted the carbs. Next day, same thing happened, car drops to about 500-600 rpms at a stop. So I checked the timing. Timing was now at 10 instead of 15 TDC. After I adjusted the timing, I adjusted the carbs. Found oil in the rear carb. Here's my questions.
1. Why do valves need to be adjusted and how many miles between adjustments?
2. Why did the timing change from 15 to 10? (Related to the valve adjustment, if not, then why did it change)
3. I found oil in the rear carburetor, why is it there (photo attached showing how much)
Brought the car back to the mechanic, told him about the timing, that I found oil in the rear carb and I re-adjusted the carbs. He said cars running too lean now. As he was trying to adjust the carbs, he told me he feels there's something wrong with the rear carb. He put his fingers in the tail pipes and said you have oil in the right pipe, which comes from the rear carb.
4. He told me to remove the slow adjustment screw on the rear carb and see if the rubber seal is worn. He's trying to figure out why the rear carb is having a problem. Both carbs were completely gone though by him and a rebuild kit was installed some years ago.
5. He thinks the camshaft is worn and needs to be replaced.
What I find interesting is the car was running tip-top except for the tapping noise. Idle was great, as was performace. Now I have these issues after the valve adjustment. (Well not sure about the oil in the carb and tailpipe as related or not to the valve adjustment)
