Misfires and engine dies. Need help please
Posted: 13 Jan 2012 20:55
have a 1970 2dr 510 L-16 , 5 speed dog leg tranny, Weber 2 barrel dcoe 45 9, Cannon manifold, 2 1/2 straight pipe, Matchbox Electric Igniton, 200sx electric coil(Wired right), Stock fuel pump(Had a new one but broke),New dizzy cap and rotor, New fuel line and vent line, New clear house filters(Gets fuel fine), Just did a oil change haha , New starter. I set the ignition timing to 11 btdc yesterday with a timing light installed new ngk r sparkpugs with a 0.41 gap for the dizzy specs, It runs smooth but rough at the same time and still get the misfire and die problems.
Well i been having this probably about a month now it is my daily driver and i am stumped now
This is what happens While im driving on the street everything is fine i hop on the freeway to drive home everyday 20 miles and i get misfires and engine dies and it hiccups and backfires like 5 times a day i try to step on the clutch and press in the gas when it misfires so it wont turn off but it turns off the next quarter mile Ill have to pull over and start it up again and itll sputter but the clear filter on top of my engine would be empty, For the last two weeks it was running Fine but itll just overheat pass the mark on the temp on the freeway and when i get of itll drop down to normal so i decided to retard the timing and got messed up. I havent touched the carb so i was thinking its really dirty jets or flooding alot. Im really iof help, I cant figure it out? Anybody know ill appreciate the help. I really dont want to get rid of her but im getting tired of the problem
