ok i just picked up a 78 C10, the previous owner just replaced the head gasket, didnt mark the rotor or body so the timing is way off, he also lost the keys, well today i had a lock smith come and make me a set, he cranks it over and it back fires blowing off my air cleaner setup i made, through the carb.

i messed with it all tonight after i got home from work, its out im the lot next to my house, im using floodlights for light and im sweetin like a pig, but anyways

not i got it down to crank over and almost start but then backfire out the carb again.

now i dont want to take off the headers and find TDC like tht unless i have to, is there another way to find TDC without alot of removing parts and such like gaskets.

thanks for any help.

 

Disable the ignition and fuel. Pull #1 spark plug. Have buddy put finger over spark plug hole while you slowly tap the motor over with the starter. When buddy's finger pops off the hole from compresion stop cranking. Turn motor over by hand to line the balancer mark up with the 0 on the timing pointer. Pull distributor up some so rotor movers. Point rotor just before #1 terminal on cap so that when the distributor (dizzy) is dropped back in the rotor lines up with #1 terminal. If the distributor wont go back in you need to pull the dizzy all the way out and with a long screw driver align the oil pump drive with the slot on the bottom of the dizzy gear. After its dropped in snug the dizzy down but not to tight to allow it to move. The timing should be close enought now to allow the engine to fire after you reconnect the ingition and fuel. With the engine running set timing with the light.

 

thanks for the info, i know about that stuff because thats why me and a friend did on my camaro when i had the same problem, but its 11:35 pm and im tring to get it running by my self tonight so i can drive her tomarrow to get insurance on it and then go pick up my 454 4sp truck that i got for free.

 

ok instead of having your buddy put his finger over the hole stuff a tussue in the hole to plug it up and wait for it to pop out..you will hear it....

 

dam great idea, thanks, ill try that right now.

 

 

ok well i did what you said, and got the timing as close as i can, but still wont run and stipp pops out the carb, im gonna have to put off pickin up that 454 tomarrow which sucks, but looks like tomarrow all day me and my girl will be working on it to get her running.

 

did you get it running? What was the problem?
