Good afternoon,
I have several questions.
I have EST and am confused about manual specs for timing.
As per manual - Initial timing should be around 1° and then:
With timing light still connected, start the engine and run at IDLE.
Verify that timing did advance to :
• If initial timing is 1° BTDC: 12° BTDC, plus or minus 2°. At 2400-2800 rpm maximum
(total) advance is obtained and should be 23° BTDC (plus or minus 2°).
• If initial timing is 1° ATDC: 14° BTDC, plus or minus 2°. At 2400-2800 rpm maximum
(total) advance is obtained and should be 25° BTDC (plus or minus 2°).
• If initial timing is 2° ATDC: 15° BTDC, plus or minus 2°. At 2400-2800 rpm maximum
(total) advance is obtained and should be 26° BTDC (plus or minus 2°).
1. How do I get a reading of more than 12° as timing tab and mark on damper are only showing up to 12°
2. Manual states 1° and then advances values but on I have plastic cap on my engine and timing BTC shows 8° (pics: https://ibb.co/yV1SPTP)
Thanks in advance!
