Next Lesson for the Rookie - ME!
 

ALL: I've mapped out a plan of attack on Clyde's "spinning motometer" and hope to tackle that project this weekend, thanks to you experts. HOWEVER, in the last several days, each time I turn the gas off/on (Clyde is a '29 CCPU) under the dash, the on/off switch gets harder and harder to turn.......is this a "take-apart and repair" or buy a new one issue?? What causes this?? Any suggestions concerning proper procedures/sequence of events??

Re: Next Lesson for the Rookie - ME!
 

rust, can be fixed drain gas outside shop good ventilation, remove valve, take apart, and possibly lap the two parts if not grooved bad. toothpaste works, take your time. If not may have to buy new one, Berts,Brattons etc vendors have them.

many times they scar due to rust particles. i would buy a replacement shut off and also install the stand up pre filter screen in the valve
very important to hold back debris particles

Re: Next Lesson for the Rookie - ME!
 

I would remove the present one and clean it up and lube it. You know it fits properly and does not leak. Only put a new one on as a last resort. I try to keep my cars as original as possible whereas some others choose to take the easy way out.

My original was leaking so I put in a replacement. Had no problems with the replacement but overhauled the original and put it back in. Worked fine.

But, I put the replacement back in (and put the original in a labeled bag in my 'keeper' bos) because I liked the longer handle on the new one.

Mine is a driver that I try to keep stock.... With a few exceptions

As above, But buy a kit from Brattons.. It will come with new packing etc..

Re: Next Lesson for the Rookie - ME!
 

Mine is beginning to become tight to turn also. What type of lube should be used? I have read post that MMO helps to prevent the valves from sticking. Will it help loosen the fuel cut-off valve?

Re: Next Lesson for the Rookie - ME!
 

There is no way to lube it ... On the inside its brass to brass. It needs to be taken apart cleaned, re-mated together, & with new packing..

Re: Next Lesson for the Rookie - ME!
 

Thank you all for your courteous replies - I am learning as I go! That said, I'll try taking it apart this weekend - what should I be looking for concerning "packing?" I think I will also just purchase a new one from Mike's Affordable (my go-to guy), and have it as a spare should I ever need it.

I took my original valve apart, cleaned it, lapped the valve with toothpaste, and reassembled it with a bit of oil. I use good gas with 4 ounces of MMO with each tank full, and after 12 years or more, it still is drip free and turns easily.

Re: Next Lesson for the Rookie - ME!
 

The best thing in the world for a dirty tank is to clean it! Take the valve out and all the gas is out to. Then throw a gallon of gas in there to flush it. After you're satisfied that the tank is clean, rebuild the valve.

I had the same thing when restoring my coupe. It was really tight, so ordered a new one from Snyders. What an amazing difference. The internal filter screen is a must.
