·Does anyone know how to set up
Does anyone know how to set up the timing on my 308gt4 with 'single' distributor.
My WSM specifies how to set up timing on the twin distributor model only, as follows: Set timing at idle (850 rpm) to 6deg BTDC. The microswitch under the accelerator earths out the first set of points as soon as the peddle is depressed, the second set of points govern the timing from then on. The second set of points are further advanced and the result according to the manual is that the timing advance will be 16deg BTDC at about 1100 rpm (only just above idle). It also states that the advance mechanism will increase this to 34deg BTDC at 5000rpm. Then of course repeat the whole process for cylinders 5-8 at the corresponding flywheel marks. The reason for two sets of points was something to do with low emmissions at tickover or something?
On investigating my car it appears to me that on the single distributor model the second set of points governs cylinders 5-8 and does not act as an instant 10deg advance. Therefore I am assuming that when I press down on the accelerator peddle I am not hitting any microswith and immediately advancing my timing to 16deg BTDC?
I recently adjusted valve seats and rebuilt the distributor. I set the timing at the 6deg mark on tickover as per the manual without really thinking it through. When I checked the advance at 5000rpm it was not reaching the 34 deg mark.
As there is only a limited amount of timing adjustment possible on any given spline, I need to get a half decent static time set up before I can strobe it in accurately. So how do I do it??
I read in a recent post of 'Harry' that he had is timing set at a dyno tuning shop to 34 deg at 5000 and it resulted in an advance of about 11deg at idle. Should I start with a static time to the 16 deg mark, or the 6deg, Or somewhere in between?
Anyhelp would be appreciated! It is worth noting that the car runs and drives well but feels under powered in it's present set up, which I am now convinced is wrong!
