when I am setting the timing.....the car idles smooth as silk around 25-30 degrees BTDC.....right now, according to the timing indicator that may have slipped, 6 degrees BTDC, causes the car to shake and rock, in other words a poor/rough idle quality.
(In nuetral with no load on the engine, the motor revs nicely and has great pick-up off of idle, no missing up at higher rpms, just a rougher than desired idle...this is why I thought I was good to go>>until I tried to go for a test drive and seen how bad it was when I tried to accelerate under a load>missing/backfireing)
A better description of the miss/backfire--it isn't just one or two that are spaced apart really far.....and it isn't a consistent rapid miss/backfire either. It is in between these two extremes you asked about. Because of the sound and it's changes....I'd have to say that it is a combination of miss/backfiring through both the exhaust(mostly), and a few out the carb (upon the initial attempt to accelerate). I'm not used to carbed vehicles....this repair is a favor for our father-in-law. I also notice that at the present timing(6 degrees BTDC) alot of black un burnt fuel seems to dominate the passenger side exhaust outlet(car has a true dual exhaust). I do not know what is normal for a carbed engine, in regards to the amount or coloration of the exhaust....I can say that leaded fuel stinks horribly...glad to see they don't use it anymore...accept in these older cars--YUK>>LOL!! |
