I'm having trouble starting OS 70 with Sullivan starter.It takes forever,turns slow and gets very hot.I've to use the car battery all the time,the one in the box in a fully charged state will not even turn the engine over.
I think my best bet is to get another starter,but I would like to get one that will turn the 90 with no hesitation.
I guess my question here is;
What is the mighty starter the king of all starters?
P.S.
Please replay only with your personal experience,no manufacture claims.

Hi
I use the Thunder Tiger Starter from HeliKraft with 18V Drill Battery.
I have had no problems with starting.

Ditto on the drill. Dont waste $ on another starter. NONE work as well as the trusty DeWalt.

Check out a new starter for 90s on Heliproz main
page. Looks like a great starter. Only 60 dollars.

I'm with CJW, I just bought a Sullivan DynaTron super hi-tork starter (12/24V) and have no problems starting a os91 with 24 V. It will turn it over VERY easy.

If you keep doing the same thing…...you’re going to get the same results!

I would hope16.8 volts starts a 50.
Al I think he’s talking about 90 size engines.



The less time I have the more I get done.

The DynaTron has plenty of power on 16.8.to start a 50/80 or 90. Even the dreaded flooded YS91. The speed is a bit abusive on 24. My set-up starts a G23 gasser, also.

The Dynatron works well starting a YS91 with 14.4V. Mine starts it first crack every time and I like how it looks.

Take Care,
Cheers, Patrick

If you are handy.... open it..yes the Sullivan is the all mighty if you are not handy ,,live it alone!! once the brushes leave the armature if you don't know how to put it back...well.... you will need another starter.. it looks like you've been running it for long periods. the contacts inside get hot due to resistance.. the most probable cause is you have a bad contact inside in the area of a conector or even the brushes.


This is why is slow and getting hot!

mine has over 18 volts... not only starts a gasser..the first time I used it. it ripped of the clutch of a raptor!!, snaped the screws!! now I tight them good!!

I had someone make the carbon frames for me. They aren't making them anymore or not for a long time from now because they are too busy at the moment.

Take Care,
Cheers, Patrick
