Ok I pulled the engine from a 1978 Mustang. It was a good runner. Replaced most gaskets but left the heads and bearings alone. My pinto engine had a new carb so I swaped that over to the mustang motor.
Now the motor is in, but very very hard starting. Turns over fine with no spark, but with spark is struggles.... rrRRRrr... rrRRRrr... rrRRRrr... rrRRRrr... fires up!
I set the timing to the sticker under the pinto hood @ 12 BTDC but the mustang hood sticker says 10 BTDC . All with no vacuum lines attached, then reattached when done.
Just to confirm , where does that dist vacuum line go, ported vacuum on the carb right ?
Any help would be great. Thanks !
