Need input again....

[fienloco]

It starts as it did a long time ago when I first got her. Now my issue is timing. My cam and crank marks are all in line. Now today when I went to dial her in to ten degrees before TDC all I can get out of her is fifteen degrees before TDC.... I am at the end of the adjustment slot, I turn her back a tooth to much retarded I turn up a gear too much advance no room to adjust.... I am stumped seems to run ok stumbles right when I step on the accelerator them fires off. Gettn a bit hot due to a bad thermostat and the clutch fan is crap. Not enough to think its timing really. Got a Fluidyne puller fan that I aint too sure on how it installs since it didnt come with directions also cant figure out where the A/C wire runs to. Im beat! A week of a head job and still need more info than a Haynes manual has to offer as they are not direct with the 87' shes an odd ball out of the class. They describe more on the 92' and earlier to 88' then 86' and back and so on. What do you think of the fifteen before TDC??
