Fuel pump is new too, its working well (it did the same with the old one). It musn't run lean, the emissions values were good when my exhaust manifold was in one piece (now it has a bad crack so we are unable to measure true values, need to fix that too). Other thing, if I change the two vacuum hoses connected to the advancer, then if the engine is cold, its detonating, when is hot, it doesn't (but jerking remains, thats how i use it now..). Also, if I change the two upper hoses connected to the second solenoid valve located at the left side of the motor (which connects directly the advancer's upper line with the switch), then it detonates at greater load, and doesn't detonates at lower load. Also, you cannot adjust the mixture at this type of carb, you can only adjust it for cold conditions.
Btw, what do u mean under bad carb? My mechanic told me, the only thing he can believe, that my carb generates too much vacuum (because of worn carb gaskets) causes the advance to immediately pull maximum timing for the distributor at wrong throttle standings (sry for composition, hope you understand what i mean). He advices to rebuild the carb but i doubt that it causes the problem (i don't have much talent in cars tho). Rebuilding it would only consume a lot of time, energy and money again with no result, i fear. Plus its almost impossible to get a rebuild kit...
So tomorrow im gonna compare the advancer's advancing range with the old one to see if it really pulls too much...and check every solenoid valve and vacuum hose related with the advance..no other idea.. the map..:
