OK I have a question for anyone who can answer this. I had to pull the timing belt off to fix and oil leak and I also put a weber carb on my 1989 2200, well now once I put it back together it wont start and it cranks over way faster then it did. I know the timing is off but damn it I got it set at TDC and got the cam gear set up with one on the arrow like it should be, But it still wont start. I am getting fire and I also am getting gas but something still isnt right, Anyone have any idea other than timing not being perfect??? that seems to be the only thing I can think of, thanks in advance

ok this is whats happing your timming is sliping a lil bit there is a special method of putturing ur belt back on put it on the a for the cam and top dead center but when ur aligning the a for the cam set it a tooth or 2 back then but the belt on and turn the cam to tighten up the belt then put the tensioner on and everything your trieing to tighten up the side of the belt that the tensioner isnt on kinda hard to explain but ill keepo n postin to help you out

also if you got a new belt there is 2 belt sizes and there liek a 1/16 or so of a difference in with so if the new one is a bit bigger its sliping at the bottom of the crank so check that out too

Your timing is off.
Do a compression test and that will confirm it has no compression on the cylinders.

well I talked to Maztang earlier and he told me to change up the cam gear when its top dead basically I am guessing my cam isnt where it should be with the crank. So I am gonna work on it tomm. I know the motor is still good and I get good compression I drove it about a month ago befoe I started taking it apart.. Thanks for the help and I will keep everyone informed on whats going on with it...

if its turing over to quicly your not getting compression...did you take the cam gear of the cam?...if so next time a punck is a ferfect marker...works on anything connecting rods..cam caps everything...set the bottom then figure out the top...it sounds like you got it 180 off or sumin silly though..some cars are stupid.. like a dodge avenger...1 tooth off and the bitch wont start i tore one down 3 times before i figgured out what was up one time..( ive never been inside a 2200 motor)

have you tried doing what i said earlier? if so, and it still did not work than do this...

like i said earlier, put the #1 at tdc (make sure that the timing marks on the crank gear line up with the timing mark on the eng. block), put the #1 on the cam gear pointing up, install the timing belt, stab the dist. so that it is pointing at the #1 plug. try to crank it, if it does not crank, remove the belt, pull the dis. out a little, and spin the cam to # 2 and try again. go all the way to #4, if it still does not crank than do it again starting with the #1 again. go 1 thru 4 again and it should crank in there.

also, you can check to see if your belt is slipping by putting the #1 at tdc (match up the timing marks on the crank pulley to the block), #1 on the cam gear pointing straight up, and belt installed. spin the crank 2 full 360 degree rotations, lining the timing mark on the crank pulley back up, if the cam gears arrows aren't lined back up than you have slack in the belt somewhere or it is slipping.

i don't know why mazda made the cam gear so that you can put it on any way that it wants, poor design but what can you do?

let me know if this helps, if not we will try something else.

also, did you make sure to hook up the distributor advance from the carb? this won't keep it from cranking but it will keep it from running right after it is cranked.

let me know bro, later.

Something else Make sure that the cam is on its power stroke when you do all this. I did that once and done somewhat what yours is doing
