Many of us aren't purists in that we use a starter connected up to the field battery. I have a Hobbico 120 starter.
My question is.....these are great for use with planes that utilize spinners. Can you get a smaller rubber cup for
use with those spinners that are small? Tried to fire up a K&B .65 that has a small weighted spinner. The rubber cup
in the starter is too big. And, does Tower or Hobby People carry these?

Dave...

Sounds like your starter cup is too big . Pull the rubber cup out of the metal housing and flip it over. Most of the rubber cups have a hole in the back to clear the bolt that holds the cup housing to the starter motor shaft. It may fit as is or you can wallow it out with a pocket knife. Then flip it back around as needed for the bigger spinner. Put it in backwards for the smaller spinner.

Kool!!! Will have to look at that. Didn't know you could use the reverse side.
I love this!!! Ya learn something all the time!!!

Dave...

Yep. And my rubber insert is so worn I really need to think about buying another one. (From starting four stroke engines without spinners. Those locking nuts are hard on the rubber. )

Yup just flip it around. That's what the hole is for. I have 2 starters. One set up for spinner's and one set up for smaller spinner nuts. I use Sullivan white inserts. Works fine for me.

Dave-

You may need to get a different insert. I have a Hobbico starter. It works fine with a large plastic spinner. Reversed, it works fine with just a prop nut. When I tried to use it on a "heavy hub" spinner nut, neither way will work. It is too big the normal way and won't grip it the other way. I bought a Sullivan replacement hub at my LHS that works great. I think it is for "medium" size spinners.

I can't imagine how heavy your flight box must be
I've got a starter, I leave it home unless I'll be flying a plane with a 4-stroke (can't reach carb to prime), or taking a boat to the lake. I always start my 2-strokes by hand.

not many people know it, but unless you are running a pump, you can prime with the exhaust instead. Just go full throttle, cover the exhaust outlet, and spin it over by hand a couple times. end result is the exact same as covering the carb.

(this might work with some pumps, not sure though, it should work with one-way's/regulators fine)

Chuck, I have my flight gear spread out over 4 different boxes. The second starter (set up for spinner's) sits in one of the boxes that usually stays in my car. There is a starter and a ton of spare props and some spare hardware in it. I have a small home built box that has the battery, nilighter (and a spare one) with the starter (Sullivan Hitorque) in it and nothing else. My flight box has tools, spare glow plugs, clevises and so on and spare props for the planes I am flying. I also have a Dubro fuel can and pump. All light and small. So weight is not a problem. Most of my spare stuff never comes out of the car. I adhear to the KISS principal.

I always prime my my engines by putting my finger over the exhaust. I find it much easier than trying to cover the carb with the prop right there. Don't have any pumped engines though.
