can someone please give me the TOTAL mechanical advance for an automatic 308 HQ engine, happy to go with stock figures as the engine is only mildly worked, and i can slightly retard it if needed
i have bought an adjustable reading timing light, and want to check the timing on full advance
i am used to timing on full advance, coz thats how it's done on my BSA rocket lll and my triumph bonneville.
thanx in advance, johnny

modified holdens like 30 to 34 degrees of TOTAL timing. So put it in neutral, timing light connected, disconnect the vac advance and slowly increase revs until you see the timing stop advancing. this is the point where the dizzy has advanced the most its Edited by user Friday, 13 February 2009 3:31:11 AM(UTC)

Wouldnt that give you even more Advance(in Total)??

thanx VH
the dissy has been modified, so wasnt sure where to start
the figures i got were 32 degrees full mechanical advance and about 16 initial at a fast idle. these were shown by using my adjustable timing light with a new harmonic balancer

If at first you don't succeed, just call it Version 1.0 |

thanx D.T.
yep, i always check timing with the vacuum disconnected and carby plugged
guess i was lucky with the dizzy, it came on a petrol motor that was supposedly worked, and had been rebushed and obviously re-graphed
