My engine which i just rebuilt drove kinda funny and had been pinging horrendously for a long time, and i finally checked out the timing now that i have rebuilt the engine. I found that at idle and the vacum advance disconnected that the base timing was at 38 degrees BTDC!!! The sticker under the hood says that it should be set at 5 degrees BTDC. So I adjusted the timing to retard until i ran out of adjustment in the distributor. It is now set at 15 deg. BTDC.
The car runs great in the low rev range, but now the engine feels winded in the top end. My initial guess is that the centrifugal advance is shot which is why i don't get more necessary advance on the high end anymore and is why the engine feels good on the bottom end now. I haven't paid very close attention to the timing as the was revved when we had the timing light hooked up, but my guess is that it is not advancing as it should.
Is this a common problem with the corolla's? I see in junkyards that 4 out of 5 4A-F/E engines have them already removed. If i remove my distributor, what should I look for?
Thanks!
