timing chain

i am still having problem getting it to turn. i am pretty sure its on top dead center. so i removed my carb and notice my intake had gas in it. is the becuase when it backfires? i dont know what els to do

read thru these threads and sub links, it always comes down to the basics, of compression, spark, fuel and timing
verify you've got spark at the plugs, that your TDC marks on the damper are correct, and the cams correctly indexed and your distributors indexed correctly fuel pressure and no vacume leaks and your ignition timing and valve adjustment are correct
 
i took apart my timing cover again and i figured out why it wont start. i had my timing marks wrong. so instead of dot to dot, it was lined up dot to triangle. do you think i did any damage to my new parts?
 
if a compression test shows no problems your chances are about 99% that you got away with zero damage
your potential mis-alignment or incorrect indexing of the cam, problem and the time and effort it took to deduce the cause could have been very easily avoided , by now the cost of cam indexing tools and the minimal extra effort it takes probably seems like a minor inconvenience compared to the aggravation, resulting from having used the wrong indexing marks on the timing set caused you, aggravation thats easily avoided because you can see exactly what the cams doing with a degree wheel and catch mistakes far earlier.

and yes before you ask!
I ALSO LEARNED THE HARD WAY,JUST LIKE 90% of the people in this hobby, by being hard headed and too cheap to buy the tools at first so your hardly alone there!
 
i am having broblem with my marks i think. when i line up the dots and rotate it so both marks are at 12 oclock, is the #1 cylinder supposed to be at top dead center? because i got a straw and put it in the #1 spark plug and it was not at top yet
 
i read those links over and over. i think i have to remove my crank sprocket again.
but last time i did that i had trouble installing it back on. is there a special tool or that?

lets drop to basics,
the crank socket has an index groove that matches a key in the crank snout, and you must use the matched set of timing gears (cam and crank) not for example use the new cam gear with the old crank gear for two main reasons, first the old gears have formed a wear pattern, that won,t exactly match the new chain and that tends to accelerate wear on the new chain slightly, and second , different manufacturers tend to mark and index the gears slightly differently, and while in theory both the pin in the cam gear and the woodrif key in the crank gear limit the chances of a mis-match theres occasionally a couple of degrees of difference in mis-matched sets
be aware that some crank gears have more than one index slot to index to the crank key and each slot is marked and you must use the correct matching marks indicating (ZERO) that match the crank slot marks

look closely SLOT A uses a different TDC mark (A) than slot (R), which has its own TDC mark(R)

most guys oil the crank snout and heat the crank gear slightly and tap it on with a large socket

but yes theres a tool

notice the (O) thats supposed to be indexed at 12 o,clock
and matched to a cam timing gear at 6 o,clock, which temporarily places the #6 cylinder at TDC, you then simply rotate the crank one complete turn, bring the cam timing gear to its 12 0,clock position,and the #1 cylinders at TDC and you can drop the intake on, and distributor in and adjust the valve lash clearance (solid lifters) or pre-load (hydraulic lifters, and set the ignition timing at about 8 degrees btdc as a starting location

you can use a dead blow hammer on the crank gear tool above or the damper tool on the crank gear tool above to install the gear

oh ok thanks. i should of thought of using the damper tool.

i just think i put the crank gear on the wrong key now that i read more
