hey i have a edelbrock 600 with an electric choke

the cars not on the road yet

but i started it up tonite and my friend noticed the carb shot a spark when i gave it some gas...............

what could be wrong??

 

Shot a spark as in backfired????

Thats is usually timing/ignition related.

Check it out & epost with more info such as initial timing & total timing ect....

 

ummmmm yeah..........it did back fire.....

now as for timing........ i dont have a timing light and i'm not 100% sure on how to adjust it

but thats the class i have in auto tech school today......so hopefully i can have an answer latet tonite

thanx for your help

 

ok i was talking to my professor in school and he said that the timing is too advanced

what is an ideal timing setting for a 305 with no CC?

 

Shoot for 8* BTDC to start with. Make sure you have the vacuum advance line disconnected while setting timing and keep the idle speed low (600 RPMs max) so that the centrifugal advance system is not kicking in any advance while setting timing or you'll never get a correct setting.

What kind of distributor is in the car now? If you ditched the computer controlled carburetor you must also ditch the computer controlled distributor. Once the ECM sees that various emissions devices have been removed (including the cc-carb) it will go into "limp home" mode and supply the cc-distributor with a very weak advance curve. You won't make any power, although it should still idle and drive acceptably.

If you use the computer controlled distiributor but don't plug it into the computer you will get NO advance whatsoever. It may idle OK but it'll be a total pig to drive.

 

hmmm i'm not too sure on what the car has because i just bought it two weeks ago............if i dont have to work tonite, i'll check it out and post tonite..........thanx a million guys!!!!!!!

 

ok, i checked out the timing----i couldn't figure it out because i didnt see any numbers........

it just had a white dot on the harmonic balancer and like a jagged piece of metal with a groove in it.........

i'm assuming that there is a special way to read this......

can anybody help me out?

if it helps, the white dot was to the left of the groove
