Ok i we finished puttin in the 302 in my fathers mustang, and once we start to crank it, it soundslike its going to crank and then bam,the carbruetor catche on fire.... I dont have an aircleaner or any paper element on it... it catches fire towards the inside-middle of the carb....

when the engine was out of the car... we took the number 1 cylinder
and put it at TDC and then put in the distributor..... 0

so idk if the timming messed up or what.... do you think its has to much fuel, or too less???

mattdel

timing is off. you are firing spark with the intake valve open.

Does it go boom to like its backfiring? Im guessin too much timing.

Was the piston at TDC compression or exhaust? Your timing may be out 180deg

mattdel

yup

thats wat is probably is... 180 degrees, off..

so how do i go about fixing this.....


should i take the dizzy out, then turn the crank another 180 degrees, then put t he distributor back in??

mattdel

just lift the distributor a bit, turn the rotor exactly 180 around, and stick it back in.
obviously, you should know that it turns even more when you mesh the gear with the cam. make the appropriate adjustments for that, and you'll be all set.
