well,before i shelled out $$ for the new one,i had the secondary one double checked,it held vacuuum,so i now have the front one off to check it. also looked in a friend's motor manual, choke setting is set righr, at 1 rich. i was told by a local mechanic to set it at the index mark,or 1 or 2 lean,to open it up more. this sounds like a good idea to me, if i was to set it richer,my problem would be worse. o No:
Jeff, The only way to learn is to take a chance. If it doesn't work, you can put it back to the way it was. It's hard to tell over the internet whether the choke is too lean or too rich. Go lean a notch, see if the engine likes it. If it doesn't, go one notch richer. Let us know :TU:
Some things to consider here: 1. As springs age, they lose their tension. This includes the springs on the choke. In this case, they typically create a leaner condition. You might try bending the link on the choke blade itself. The newer chokes were riveted to the housing. Slightly bending the link counterclockwise with enrich the choke without messing with the housing itself. The link is on the passenger side directly connected to the tang on the choke blade. The idea is to bend the link a little more to enrich the setting, and to bend it more straight to lean the choke. Note: this works for slight adjustments, and only if you know exactly what you are doing. As with anything metallic, the constant bending will break a part very difficult to replace. Make the adjustments carefully, and be aware that SMALL adjustments are all that are needed. Ray
will try that. fortunately,napa has the spring & the plastic housing new for $10,so i may pop for a new one,to have on hand.
A wise decision. When and if you install the new one, be careful to properly install the tang on the spring in the actuator on the choke. It will need to go into the opening. It is very easy to miss the opening, which is a slot, and have a choke that either will not open or will not close. If you use the new one, I suggest setting it to the original setting, as the spring will weaken with age. Also expect the choke pull-off to fail soon as the additional tension provided by the new spring will likely cause it to fail. That will cause an after start-up flooding condition. This will also be the perfect time to check the linkage for binding, and to check the fast idle settings. Also make sure to check the vacuum advance diaphragm as well. A defective vacuum advance will cause poor driveability, a vacuum leak, and a slow fast idle. Ray
went 1 notch richer, the bog went away. i let it run for a couple minutes, then backed it out, gave it some gas, no bog, seemed better.now,when it warms up, do i need to put it back where it was?
No, leave it. Warm the car to operating temperature, remove the air cleaner lid, and verify that the choke is opened all the way. That's it.
no, i meant put it back when the weather warms up in the spring. watched choke ,it opened ok so, i think i have it fixed :TU:
Actually, no. Leave it. The reason is simple. As the weather warms, the spring will warm as well. In other words, the tension on the spring is dependent on temperature. As the temperature rises during the warmer weather, the spring will lose some tension when cold. This will reduce the closing tension on the choke. The spring will then be easier to warm as the engine warms, and the result will be an open choke with a warm engine, regardless of the cold position. It is very likely that the one notch richer will assist the warmer weather operation as well. One thing to be aware of is that the engine will tend to run at an elevated idle if the choke does not open completely. One notch should make no difference. One other thing to remember is that, if your choke uses hot air for heating, the lack of a heated air cleaner will affect the opening of the choke. In that case, it might be advisable to use an electrically heated unit from a later carb. If that becomes an issue, we can cover that at a later date. Let me know... Ray
am using 87 octane now, sometimes 89 octane which is best? have been tempted to use some of that 10%ethanol, but am worried about what it will do to my fuel system? choke problem is better now,opens fully
If you are using 87 octane now, and it does not ping, then there is no advantage to using 89. Using higher octane than an engine requires is nothing but a waste of money. Are you sure that there isn't any ethanol in the fuel you are using? In N.Y., all the gasoline has 10% ethanol. I have been using it for years with no problems.
it is available at only one place here where i live, is only 2 cents higher than regular.($1.71, regular is$1.69) i rarely let my tank go below 3/4 tank, so 5 gallons or so shouldn't hurt
