[!jAsOfRaW!]

Hi,
I have the 4.6, works fine and was using it at local bmx track and it turned off, when i tried to turn it back on the rotostart stick wont turn when inside the thing where u put it in, i have also checked if flooded and its not.

any input will be great thanks

I'd suggest taking the roto start apart on the engine. You may have broken a gear in there. If you don't have a busted gear or something in the roto start, then you have internal engine issues like a snapped con-rod.

Does the wand work when you don't have stuck in the engine?

yeh it works without glowplug and works just as spinning by itself, also the flywheel is turnable without glowplug when i just use fingers, so I'm thinking cos another guy said new engines have a lot of compression that its just low battery

Yeah, that could be too. Try backing the plug out 1/2 turn from tight when you fire it up. Once it's running, tighten the plug back up. It will alleviate some compression and make it easier to start. I had to do that with my LRP28. It's a pull start, but it fought me tooth and nail for the first 4 tanks.

It also helps to put the piston just past its' compression point, on the down stroke. That way it gets a running start before having to make compression.

its all good now, just a low battery
