Drove like dream last night, fired once this morning, now turns over but won't start. Acts like there is no spark but there is. I've used starter fluid ,I tried A little gas but will not fire. Help!
First I would pull all the plugs and confirm that they are not wet. If they are then dry them off with some brake clean or the like. Even dipping them in rubbbing Alky works! reinstall them and then jam the choke open with a big screwdriver and see if the motor kicks at all. If you have enough spark energy to trigger a timing light ( check this) and if the motor did not even kick a little with SF, then I would suspect a failed timing chain. pull out all the plugs and remove the Dizzy cap and by looking at the balancer bring #1 to the mark and then see if the rotor is pointing to number 1 wire terminal. Also spin the crank back & forth a good 4 inches and see how closely the Dizzy shaft follows that crank movement. I will bet you have a ton of slack! in my lifetime I have had two timing chains in two different brand motors give up the ghost. Both times I was very lucky that they did that in my driveway when I shut the motor down, neither motor would restarts and neither motor bent any valves! I hope you will be just as lucky since a stock Cam in that motor does not have much lift.
If it has fuel at the carb and spark at the plugs it must run unless the timing chain is broken, then it would be backfiring.
That's what I thought. I can put gas in the carb and I've checked and it does have spark but. nothing of any kind of fire
Sounds like your down to checking the timing chain Dizzy rotor relationship like I replied to you. With this check in ten minutes you will know the story.
I am happy and sad at the same time for you, but at least with the way it failed no harm came to the motor.
