I'm looking at investing in a new starter, and I'd like to buy something that will hopefully last "forever". As such, it needs to be robust and powerful since I may at some point consider working with larger petrol engines although not any time soon.
I'm comparing two models, the Sullivan Dynatron which I know has a very large and happy following, and the J'En Geared Starter. Both items can be seen on this link.
My dilemma is that the J'En costs about 1/3rd of the Sullivan. Has anyone got experience of either/both of these starters and care to offer me their advice?

SM, please read this thread which explains how to insert links into posts correctly. If you simply cut n paste the URL it damages the page formating and results in your, and all subsequent posts, dissapearing under the adverts to the right!

Dad's been using the JE one for the last couple of years and it's been fine. Nice and easy to hold unlike some of the very big starters. I borrow it for my 1.20 four-stroke and have no problems.

I have the J'EN geared starter and use it to start larger glow engine's, OS 160 FX and Saito 150 and 180 fourstrokes, one of our club members uses one to start his 34 cc petrol engines. I have not used the Sullivan Dynatron but I used to have a standard Sullivan starter which had very poor torque compared to the J'EN starter. Don't forget that the standard 7 amp/hour 12 volt is not capable of proving sufficent current to turn over larger engines, I use an 18 amp/hour 12 volt.

|I've been usingthe JE one for years now, lots of power, I've used it on up to 35cc petrols and starts them with easy, and much cheaper than the Dynatron|

Well I think the Dynatron is overpriced and in some instances downright dangerous. Here's why.
I have used it of engines like OS 160 FX and OS 200 FS and on a cold day it struggles to turn the engine over unless you use two 12V batteries connected in series (as instructed by the manufacturer). However, this is not without danger because the cup has to be centred perfectly of sooner or later the metal cup will spin off as the amount of thread it's on is minimal. It was good job I was wearing safely glasses at the time!! Also the shaft was bent rendering the thing unusable.
I am on my second Dynatron but I think when that gives up I will try the J'EN if the posts are correct. But PLEASE, PLEASE guys do use safety glasses when starting these engines.
