Now that the engine is rebuilt stock and running great, it seems like it starts too quick. I also smell unburnt fuel, especially as it is warming up. I have my son's Strobe Light but I don't have anything to tell the RPM. Is there a way to set the timing properly without knowing the exact rpm? At my age, I need "Easy"..................... LOL

Don't need RPM at idle for a baseline. You will need to mark the timing marks on the pulley so you can see them, though. We'll also need to know what distributor as each version has it's own set of rules. Usually, by 3000rpm, most distributors should be all in by 28 or so - you can run the engine up to that by ear if you don't have a tachometer.

HF has a real nice digital DWELL/TACH/VOLT/AMP/TEMP meter for cheap on sale.  They work great (just bought one paid 30 for it). 

You can't beat having a good piece of multi purpose test equipment.

Well, I got it pretty close by ear, it is running great so I have to be close. Thanks for the input.......

Never mind, I thought you said STROH'S LIGHT. Hey, it's been a long day and I thought it was funny.

I timed it by ear and it runs great. The calibration on the crank pulley is way off.... It would barely turn over when I set it by the marks on the pulley.

What king of pulley do you have?

You can find top dead center but using the rockers. When the cam is on overlap on #3 it should be vary close to TDC on #1. You can use a stiff piece of wire down the sparkplug hole to feel when the piston is at TDC. Then file a small groove in your pulley. But, I have yet to find a pulley that far off of TDC. Even cheap ones are within 2-3 degrees I would really recommend finding TDC on your pulley timing it with a light. Chances are you are running far too advanced or retarded. I just timed a buddies car that "ran great" he set his timing by ear. 42* total advance, he probably would have burned the motor on the first long trip. Running badly retarded timing will also overheat your motor.

Thanks again Brad. I will find someone to do this for me. My blood is running low again. This MDS condition of mine is a bummer, but this little car takes care of most of the rough times. I appreciate and value your help.

No problem Bob, just hate to see someone cause themselves some expensive grief down the road. I'd come and do it for you but I think there's a few miles and an international border between us :-)

Take care, brad
By bob P 3255 Date 2015-08-06 12:36
I just knew that this international border thing would come into play here with all this border crossing and all...  LOL

Thanks, Bob
