Bump it up.

It has only been doing it since I've changed the head on the engine so it might not be seated properly. Thanks.

Okay then buddy cheers, for the reply I will give it a go.

Not really buddy sorry.

Bump any offers.

As above really my mate has a km baja 002 and is having problems with it, it will start pretty much on the first pull but as soon as it has run for a while and engine is warm it will cut out and won't start again untill it has cooled down, any one got any ideas? Cheers

Still taking offers.

Okay cheers for that I will take a better look and get it out for a run and lean it out a tad.

Haha! That was just after I put the engines in and have it a small clean up, still yet to strip it down to parts and build it up again making sure all is right and right. You see in that video where you can hear scream, high pitch engine noise, mine doesn't do that, it seems as if it is restricted and doesn't go full speed, is that just a characteristic of the 4.1 hpi engine?

Only one I have at the moment

I will start with a full strip down and go for a 3 shoe clutch with silver springs like you said.

Alright cheers

Any one else got any ideas?

I does kind of roll free but it won't roll as far as my buggy when pushed also when I am running it and let off the throttle it comes to a stop quite quick, but the brake has not engaged.

I have got a gtx2 hot bodies and I have just put in 2 brand new hpi 4.1 engines in it. I have run it in all as they should be done and I have gone through about 4 tanks per engine I am just getting round to doing some full speed tests and it doesn't seem to be putting out much power. Both carbs open out fully and it is still a lot slower than my hpi trophy buggy with 1 ke25 engine in it. Also the engines are tuned right both high and low speed needles. Does anyone know what could be wrong? Cheers Matt
