I just installed a used / rebuilt motor into my truck and when I am trying to start the truck it ran for a little bit and then died. Now when I try to restart it, it backfirs thru the carb. I need to check the distributor and see if it is lined up correct. What position does the rotor need to be facing when at TDC? I can not find my book now that I have moved, it is burried in the garage.

 

At true TDC the rotor will point to #1 wire. Drivers side front cylinder.

 

dont forget that your cam turns twice for every 1 rotation of your crank so it could look like it's 180* off but it's not

 

Thanks for the info. I just thought it was weird cause it was running just running rough and now coughs up thru carb. I will doule check the location of the rotor, I believe it was pointing towards the passenger side the other day....I will get it lined up. Thanks again for the feedback.

 

if it is coughing through the carb while your trying to start the truck you most likely have the distributor 180* off. it does not hurt to try rotate it 180*. if it don't fire up you could always rotate it back.

 

Thanks, I flip it 180 an it fired right up. I should have done that a couple weeks ago. This motor sounds frickin awesome.
