timing issue
See if you guys can help me. My head gasket blew so while I was changing it I decided to go ahead and replace my head with a port polish and shaved head that I just finish rebuilding. Valve seats resurfaced on valves and head. New springs and retainers. While I had everything off I went ahead and tied my harness off out of the way and rerouted some for a mild wire tuck. No cutting. Ended up grounding my power wire off when I hooked it to the starter after rerouting. Didn't know it till I went to crank my car and a clicking noise kept coming from my shifter. Which by the way is auto. Found the pro lemon when I unhooked the ties from my wires and saw it spark again. And you could here the pump prime as well. Fix that and went to start it and it would only spin the motor wouldn't fire. Checked my plugs for spark made sure I had fuel.even sprayed Carb cleaner in it still nothing. Went threw my timing several more times just to make sure. Now like a retard I forgot that when you shave the head you have to degree your timing. So I read up on it and found that I needed to retard the system so I move the cams over 2but degrees at first the 4 then 6 then I tried only moving the exhaust by 2 and intake by 4 still nothing. Tried replacing my main relay thinking I blew it when the harness shorted. Same thing. All fuses are good wires are hooked in the right spot. What am I missing. Could I have messed up the crash k position sensor in the dizzy even though I never blew a fuse. Ir is what I read wrong and I need to advance it. The factory settings on timing I can get a fire but barely just enough to make it want to crank. Hold the gas quarter throttle and it just about starts but back fires threw the intake and want run. So I know its timing just don't know what's causing it to be off
I did that. Thought you were meaning something else. I ha e spent 6 hours playing wit the timing trying to find out if its right. I have retarded the system up to 6 degrees on the cams tried 2 on the exhaust and 4 on the intake. Still will not start. I have had it at factory timing and that's the only spot that it will even try to start but still back fires through the Intake. I know the factory timing was on perfect. I have done that a million times on hondas. Im going to try a new distributor tomorrow and see if that's it. Im lost on it. There's something im over looking or didn't do right other than the belt I guess. Im going to advance the timing as well and check that but your suppose to retard if it was shaved.
Do you have adjustable cam gears?
Backfiring through the intake can only be caused if an intake valve is open during the combustion, [even if only a little] for whatever reason, [valve timing way off, bent valve, improper lash].
Did you do a valve lash adjustment once the new head and timing belt was installed?
If you have adjustable cam gears, did you zero them to install the timing belt set the initial valve timing?
If you have done/checked valve lash and done/checked valve timing and both are "good" do a compression test and if no good a leak down test to see where the air is going. 94

Also do a pressure-test with shop air with each cylinder at TDC compression. Any hissing from the intake at that cylinder indicates a valve that is not sealing.
If a valve is not sealing, it may not have to do with timing, but with things like a bent valve...
