Roadster getting harder to start I'm at my wits' end. My 31 Deluxe Roadster takes several tries to get it to start (but it always eventually does start). I've pretty much done all the suggestions I found here but to no avail. I have enrichened the mixture, put a secondary ground cable to the transmission, the main battery cable is tight and properly sized, I have replaced the coil and condenser, rebuilt the carburetor, checked the battery (it's fine), checked the spark (it's fine), cleaned and gapped the new spark plugs, cleaned the points, tightened and adjusted all other wires, but to no avail. The spark from the coil is good and blue, it is getting gas, and in fact runs fine and starts fine after the initial start.
Anyone have any other ideas? As always, thanks in advance! |
Re: Roadster getting harder to start How long has it been getting worse?
Is it getting colder there? Does the GAV work? I assume yes since you rebuilt the carb. Does the starter turn quickly? |
Re: Roadster getting harder to start Curtis - it has been getting worse for the past couple of months. I've had it now about 14 months and it's never started right up, but now is worse. No, it's not getting cold here. I'm on the outskirts of the desert in SoCal. Yes the GAV valve works and yes the starter runs quickly.
Thanks |
Re: Roadster getting harder to start old fuel, laden with ethanol, doesn't like to ignite. Just a thought.....
|
Re: Roadster getting harder to start Do you shut the gas off overnight?
I open the GAV 1/2 turn and choke it for about 2 revolutions so the gas gets back in the carb. |
Re: Roadster getting harder to start Yes, the gas is off when I park it. I've tried turning it as far as 1.5 turns to make it rather rich to get it going, and there is no effect on the starting capability. The fuel is new-ish.

Re: Roadster getting harder to start I am no expert for sure, but could a leak at the intake make it harder to pull the gas mixture up?
|
Re: Roadster getting harder to start Have you checked the compression and taken a vacuum reading??

Re: Roadster getting harder to start I'm with Bob on that one.
|
Re: Roadster getting harder to start No I have not checked compression/vacuum. Will put that on the list.
|
Re: Roadster getting harder to start I noticed you said "Cleaned the Points" Try a New Set of good USA made ones..
|
Re: Roadster getting harder to start Thanks FM - will do. (Adding to list)
|
Re: Roadster getting harder to start I had a similar problem and found the rotor and or the cap brass apparently had gotten corroded... I say apparently because it wouldn't start, but all I did was clean the rotor end and the top of the rotor where it blackens to the cap and the cap brass and it's been fine. Just a thought. a lot of stuff gets corroded sitting, check the coil wire at both ends.

Re: Roadster getting harder to start Intake air leak would do it. Suspects are: manifold gasket, Most likely, . Joint between carb and intake manifold, warped surfaces. The manifold itself, unlikely. When right, Model A’s want to start. Stay with it.

Re: Roadster getting harder to start Thanks - I'll dig into the distributor and clean it up and look into how to check the gaskets. Unfortunately, the distributor is stuck - big time - so changing the points is problematic. I'll see what I can do though! Thanks again.

Re: Roadster getting harder to start I guess I would follow a few clues.
First, what would not work when the engine is cold that would when it is warm? But since your in SoCal that might not help. Second, what would stick when not used overnight but loosen up after started? Maybe a throttle linkage or valve. But since you rebuilt the carburetor that might not help. Let someone else start the car while you watch the throttle and carburetor. |

You don't need to remove the distributor to change the points. Bob |
Re: Roadster getting harder to start Unfortunately Bob - Small screws and I don't mix well!
|
Re: Roadster getting harder to start Mine went the same. Eventually found loose bolts on the carb to manifold.
|
Re: Roadster getting harder to start Intake gasket leak. Unhook the fuel line at the carb. Turn fuel on for 30 sec. If the flow turns to a trickle then you have something plugging the shut off valve.
