Henseleit 3DNT - Rocket - 3DMP > 3D-NT Starting Setup

I have a problem. I have the clockwise rotating OS 91 in my 3D-NT. (So the M/R turns clockwise as well.) When I use the starter to turn the engine over the 6mm hex drive screws the set screw down into the starter cone and bends the bolt. When I continue to start the motor the bolt bends even more and eventually I have driven the set screw so deep into the cone I have pushed the starter cone out of the fan. (It is working like a wheel puller against the bolt and breaking the sides of the cone where the bolt goes through it.) I have been using the blue locktite to no avail.

The engine is new so I am backing the glow plug out about 3/4 of a turn.

Has anyone else had this problem? If so, what did you do to correct it?

Thank you - Sam

Yep, been there and done that

Don't know why Yan didn't use a reverse thread on that bit - just for us 'clockwise' junkies

I got a new one, and epoxy'd the hex at the top of the thread. The bits are so cheap and I've not seen one wear out yet so theres no need to worry about 'screwing things up'.

I've been having to remove the plug on mine and running fuel through on the first run of the day for a while, don't know if it's my 'cheap' starter or just because I don't get to 'play' as often as I should - even pulling the fuel feed from the carb to stop the engine leaving it dry doesn't work.

The rest of the day's running is fine after that first run through, it's just after it's sat for a few days/weeks between use.

Thanks for the reply DangerousDick. I'll clean it up and try the epoxy. Nothing to loose at this point. What I'm doing sure isn't working.

Thanks again - Sam
