Cleaning electric starter rubber cones
« on: May 21, 2023, 12:04:15 AM »
what is the best way to clean the rubber insert on an electric starter when it wont grip the spinner  or the spinner nut anymore?  I have a fairly new one that just slides around no matter what.

What works for me is an alcohol wipe down and then course sandpaper. The dark stain will remain even after the alcohol. I rub the 60 grit sandpaper in the longitudinal (in and out) direction for a good grip on the spinner. The same treatment works on the spinner if you’re not concerned with how it looks.

  Naphtha on both surfaces.

Will try these things. I tried cleaning with dawn soap did not work.  Also tried wiping down with rosonal which is similar to naptha.  I do have some naptha as well. Will try the coarse sandpaper as well.  When i use up the naptha i have i cannot buy it at a store as it is not sold at any store in denver. Dont want to mail order naptha?

Jeez, I'd think any paint store, Lowe's or Home Depot would have Naptha. It's that easy to get here in WA.

Two things I'd point out. 1) A needle nose or "Ultra" style spinner gives more traction with more surface area being gripped. 2) Sullivan/Pylon offers quite a variety of cone shapes and materials...most seldom seen at the LHS. Probably not helpful if you're not using a Sullivan starter, but one of the reasons I do.  H^^ Steve

If you can't get naptha, just use lighter fluid.

   I was delirious with drugs when I answered the first time, and I forgot to add to spend the extra money for the best rubber cone Sullivan makes. They have 4 or 5 I think, and the pink one seems to have the best overall shape, and is nice and soft so it grabs any surface better. I think they are 10 or 12 bucks but worth it and if you don't loose it, you will never need another one.

The other problem i am having is the starter does not fit my spinner nut. Even if it is perfectly clean i think i need a different type of rubber insert?

   Matt, did you rea my last replay?? What comes with most starters is your least favorable option. Look at the others that Sullivan has to offer, especially the pink one.

If the prop is held on only by a nut (no spinner), then a driver that grips the prop is needed. They’re hard to find and can show up at swap meets occasionally.

Should work now.  Problems were cone dirty and low starting battery.  Went back to using lawn mower battery which has longer run time. Other battery was low and starter would bog down when you push it into engine to get it to grip.

Sounds promising.  Alcohol to take off the oil and sandpaper to knock of the glaze and provide grip.  Any suggestions on how to ditch the "Moon Shadow" that's following me?
