backfiring and not much power
Ok guys, got my brakes adjusted and was finally able to get out of the driveway with my new toy. It doesn't have a temp gauge but it seems to be getting hot very quickly. Maybe my imagination. it doesn't have any power and backfires a lot. The hotter it got the worse it got. Any advise.

Re: backfiring and not much power
Where is the spark lever set?

Re: backfiring and not much power
check to see if your timing is not too retarded and that you carb adjustments are right. Idle mix and the gas valve that is also the choke rod. Also, you probably know this but you should pull the spark advance lever about half way down (more or less) after start up.

Re: backfiring and not much power
Like said, the the left hand lever is the spark lever. It should full up for start and about 1/2 way down [ 9:00] once running. That is, if the ignition timing is set correctly. You may want to open the GAV [choke rod] a turn counter clockwise for starting and close to about 1/2 turn out as the engine warms for most running until you find out what works best. Try leaving the gas cap loose and see if that helps also. Try these and let us know what happens.

Re: backfiring and not much power
Ok as I am new to model A's the guy i bought it from told me to start with the spark lever all the way down. Hope that will not damage anything but i will start with spark lever up from now on. While on the drive i did try to move spark lever up but power decreased. about 8:00 was as good as it got. I have always dealt with diesel engines and do not know much about timing. is there Anyone you could recommend to look at this in the San Antonio area.

Re: backfiring and not much power
Sounds like you need to start with the basics first. Get/buy one of the copy owners manuals for your Model A (about $10) and use the search function at the top of this page. There is a wealth of infor that has been discused on here. It sounds like you should go through your timing and fuel before driving anymore.
Timing how to http://video.search.yahoo.com/search...nr=20&y=Search good all around book http://www.amazon.com/Model-A-Ford-m.../dp/0965824004 owners manual http://www.ebay.com/sch/i.html?_odkw...anual&_sacat=0

Re: backfiring and not much power
like the guys before said, spark rod: all the way up is full retard, all the way down is full advance.
for starting, bring rod all the way up for full retard, once running bring the rod down some to get a smooth idle. usually about half way down. when cruising bring about 3/4 down or so. good luck. I second the idea of getting the original model a owners manual. there is a lot of info in there, pretty much everything you need to know on how to drive it. (probably why it was included with purchase of the car)

Re: backfiring and not much power
Did you watch all the videos? There is more than one.
The check is the pin in the gear and then the light indicating the points/cam relationship in the proper time for cyl. #1.

Re: backfiring and not much power
After driving my Model A for more than 20 years I discover from this thread that I have been using the spark lever incorrectly all these years!! I start with it fully retarded (up) and then gradually advance it all the way down for highway driving. In one of the above threads someone says it should be about three quarters down for normal driving, so have I harmed my engine (eg loaded up the bearings) by driving fully advanced?
Also in post#9 Christian says it idles smoother about half way down but I am sure mine idles much smoother and slower when it is fully retarded. |

It will idle much more slowly in the retarded position. Smooth running depends on a lot of other factors, like fuel mixture, timing, points, and such.

Re: backfiring and not much power
This is what Henry told the new purchaser of the Model A's about driving and timing advance....

With today's worst gas at 87 octane full advance at 4.22CR may not produce any spark knock, but will certainly present too much cylinder load while still on the upstroke. Not readily detectable by ear, you now need a very good 'feel' for how the engine behaves. Not everyone has that fine touch. The learning curve is steeper today than back when. |

Recently, I've found the car runs better on the street at 8:30 to 9:00 rather than 7:30.

Re: backfiring and not much power
If all of the above suggestions don't seem to help your no power and backfiring problem, you may want to check your head gasket..... a compression test will help to show this
