Fuel Fire and timing...if it has compression and those 3 things it has to run. You didn't by chance advance the cam with one of those 3 keyway crank sprocket things did you? If so that could be it. I tried that once and it wouldn't fire a lick.

[johnracer]

Back to basics: does it have spark at the plug while cranking? If not, does it have spark at the coil while cranking? Are you getting fuel to the carb?You said it cranks over fine. Does it crank too easy? Probably should do a compression test if it seems way too easy to turn. Anything over 70psi should start. As Tod said, cam timing could be off or valves adjusted too tight.

you got scamed by the dude that put it together.

[bigray]

i would lean towards the valves to tight..

[oldandtired]

I am bothered because you say it doesn't even spit or backfire.
1. You will know if you have fuel or not, easy to view.
2. You can check compression by compression check or even turning engine over with finger over spark plug hole.
3. You can check spark by turning engine over with SP wire to ground.
4. (as johnracer and bigray said) valves may open all the time.

I vote for #4

Im with these guys !! readjust the vavles and make sure you have spark

Solid cam, might have tried to adjust it as if a hydralic.

I would vote for valves to tight or cam timing off. One tooth will do it. If your more than that, you probably bent all the valves.

Just wanted to let you know what happened to me,Your probably alot smarter than me but it cant hurt to check-After building my motor & installing it,I also completely wired it with aftermarket wiring harness ect-I also installed a MSD Dist & a 6AL-It would not fire when I was trying to start it but I could take the dist & turn it & It would knock you to your knees!I tryed another MSD Dist & Box but same problem-After scratching sores on my head I called MSD & Fixed the problem in 2 min.I had wired the power wire from the box to a non essential bus-When Icranked the motor it killed the spark-I switched it to another terminal & it cranked so fast I couldnt get off the starter-Just something that sounds like you could also have-

I have had one that the valves were just a little to tight and it would not crank for crap. One thing that was not mentioned, if your valves are way to tight then you are not going to get a good reading on compresion until you reset them. I would reset my valves first and then check compresion. Let us know what you find (If your luck is like mine you won't want to tell anyone what you find due to it being something you did) Good luck.

POP THE VALVE COVERS AND YANK THE PLUGS.
Get number one up to TDC and make sure the valves are BOTH closed.
Check timing mark for TDC.
If all ok at this point do a compression check which will guide you which way to go from there.

Tell us what ya find ! So we can all chuckle WITH you.

Story;
I wanted to make a few easy passes at the local drag strip this Spring with my Open Road Race car. They wanted the batteries moved from inside the passenger compartment to the trunk.(NHRA rules). Did a quick and dirty to get 'em moved, towed to the strip, and it would NOT fire !??? Spun over somewhat but no bang. Took her home, switched the batteries back into the cab and ZIP - BANG she pops right off no prob.
I had performed one of those DUMBA SCHITT moves. Note moveS, plural.
#1 DSM - I had used some arc welding cable that I had around the shop to get into the trunk. Lesson ; Arc welding cable has a HUGE resistance factor !! MAJOR amp drop through the cable to the starter/ignition. Spun way slow with nothing left for ignition.:roll: :roll:
#2 - DSM - I had hooked the battery cables up in the wrong positions for using 2 batteries. I came off the pos on one batt and the neg off the other when it SHOULD have been + & - off the SAME battery. :roll: :roll: :roll: :roll: :oops: :oops: :oops: :oops:

"NO EXCUSE, SIR !"

Did you find the problem? It says moved ,to where? Just curious as to the fix-

[cubed]

Did you find the problem? It says moved ,to where? Just curious as to the fix-hi, the whole right side was way down on compression so i took head back to shop. am waiting on answer now. thank you.
