Sticky valves: what is the procedure?

That's great. The way you talked about it made it sound like you just put in a new set of spark plugs. Much more work that that!
 
Hi my name is Tom I have a 1930 model a 5 window coupe I think the valve's might be stuck. I just got this car and it is my first model a I have learned a lot reading this forum and solved a bunch of problem's with the car but it still does not run right. So far I have replaced the upper and lower plate's in the distributer with modern point's and condensor because it would not start at all after doing that and cleaning the ignition switch and other misc connections I got it to start. It ran ok for a little while I drove it around for 5-10 minutes it ran ok I shut it off and came back the next day and tried to start and drive it again it did not run as well as the day before it does not rev up at all it never really did but got worse. I noticed it had an exhaust leak so I checked for leak's in the intake gasket since it is all one piece I found a fairly large leak so I replaced the gasket hoping that is what was wrong but no change it idle's a little better but not much there is no change when I adjust the mixture screw in the cab I would think that I should notice some difference in the way it run's turning the mixture screw from one extream to the other. So my question is do you think it could be the valve's are stuck or something else like the carburator needing rebuilt or worked on. If it is the valves what is the best way to unstick them? Sorry for such a long post I hope to get this thing running soon. Thank you Tom please help Thanks
 
Do a compression check to see if you have a stuck valve. A can of Sea Foam in the gas and another can in the oil is good to free up stuck valves. A slow to close valve can be checked using a vacuum guage. Check the fuel flow to the carb, and I suspect you might need to clean the carb.

I prefer original distributor plates and points. Also check your points gap and timing.
 
Thank you I will do that I need to find an adapter for my compression tester it came with three different sizes but none are big enough for the model A plugs. I will check the timing again but I have checked a couple time's already . When I set the timing the directions said to grab the distributer cam and twist it and if you got a spark it was set properly. But after reading some other post's on here I discovered it turn's counter clockwise and when I checked for spark by twisting the cam I turned it clockwise I don't know if that would be enough to throw it off because the difference could not be hardly any I would not think. I will order a gasket kit for the carb and take it apart and clean it. I was hoping it was not the carb because that is what my father said it was and he just love's it so much when he is right :) Thank you for your reply and I will try the sea foam if the compression check say's I need to. What should the PSI be on the compression so I know if the motor is in good shape or not. Thank's again Tom
 
My compression is only 50 on every cylinder, but the engine has good power for a totally stock engine. Right now you are mainly looking for any pressure to make sure you don't have stuck valves. Dependine on your head and cam, you'll probably have from 50 to 90 lbs. showing on the guage.
 
Ok thank you knowing that will help me know if I have a other issues as well. I think I am going into town today if so I will try and get the adapter for my compression tester.
I like living outside of town but it make's it hard when you need a quick part and it is 30 minutes to get to the edge of town. The worst part is no pizza delivery when you are working in the shop :( Thank you for your help Tom
