Hi everyone! I need help with the timing for my 1973 Toyota Corolla State. It has the 3K engine with about 60.000km (I overhauled it about 8 years ago), the carburator is the stock item for this Corollas and everything is mostry OEM. About 2 months ago, I installed a Pertronix electronic module in the distributor, because points are hard to get in this times (and I'm getting tired of buying this part). According to the Pertronix site, I keep the resistance in the coil. Also, set the timing (with a timing light gun) to about 8° BTDC and put the octane selector in the zero setting (according to the Toyota manual), and set the iddle to about 800-850 rpm. However, under load and above 3.000rpm I can hear the engine pinging, the car has not power in the upper band and the economy is not the better. I try to solve this putting the initial ignition setting in 5° and keep playing with the octane selector, but the results are not the best (keeps pinging under load). When it had points, this problem didn't existed. I also have a 1959 VW Beetle with a 1600cc dual carb engine and mechanical electronic distributor. For setting the ignition, many VW web sites advises to set the ignition to 30-32° BTDC at 3000rpm, and ignore the iddle setting (it falls were it must). Thinking in this line, have any of you information about the maximun advance setting for the ignition (and rpm for this) in a 3K engine??? For your information, in my country (Costa Rica) we have 88 and 91 octane fuel...I generally use the 91 octane fuel for my car. Keep in mind my engine is mostly stock, only modifications are the electronic module in the dissy, and 4 into 1 exhaust header. The carb is in perfect condition, and also the distributor (everything is working as it should), the coil is almost new with the resistance working and there is no leaks or similar in the hoses. The car is used as a 40 years old car must be used, with care and respect (I know this is not a sport car or modern car), but this pinging sound, the lack of power in the upper rpm and the high consumption keeps me worried. Any help will be usefull...and thanks in advance for your time! Jose Garro Costa Rica
