Hi there everyone!

I've bought a Gv Models Rex X now as I want to get interested in Rc Buggies again. I bought one band new around 5 years ago but it was stolen so I didn't really want anything to do with them again until a friend persuaded me that I should get one again. So I looked on ebay and found a Rex X listed as not running for a reasonable price. I bided and won it. I picked it up and got it home. It wasn't in the best of states. Was a bit filthy, things were a bit loose, the synchros and flywheel were worn and the throttle servo was snapped. So then my friend kindly cleaned it all up for me, tightened things up and fixed the throttle servo. Then to the engine! It was SOLID!we couldn't pull the pull cord as it was too tight and tried rotating the fly wheel with our hands but it wouldn't shift. We got a friend to clamp it in a vice and he got some pliers on the fly wheel and it moved surprisingly easily. It now turns over when pulling the pull cord but is still a little tight. I had some old fuel from 5 years ago which had been stored in shade away from the sun and my old glow charger from 5 years ago. I stuck some fuel in, primed the engine, stuck the glow charger in the engine and tried to start it. It wouldn't start after many pulls until the point in which the coil in my pull start snappedSo I fixed the pull start, went to the local hobby shop, bought some new fuel and a new glow plug. Put in the new fuel and glow plug and tried to start the bloooomin thing again... but again it wouldn't start

I'm all out of ideas as to why the buggy won't start, maybe its the 5 year old glow starter although it does cause the glow plug to glow so I don't think it is!

Is there any way in cleaning out the whole engine?

All help and comments are much appreciated!

Thanks!

take the engine apart, soak it in alchol or mineral spirits wipe off put back together and use after run oil lighrly on all moving parts that should free it up alot

Hi thanks for your reply,

Depending on what engine it actually is, but the crackshaft should have a whole in the end of the big end journal. The spring goes inside the hole then there is also a pin that sit in the hole after the spring goes in. This pin is what the pull start uses to turn the engine. Have a look at the link below, scroll through to the last page and there is an exploded view of an engine. Look at the pull start assembly part #52091 and you will see the pin and spring. This goes into the end of the crankshaft journal.

As well as cleaning out the inside of the engine also pay some attention to the carby. Dissamble and clean any gum out of all the needles.

Exactly what I thought, as chooka has stated spring and pin engage with the cut out on the starter plate and when you reassemble if you rotate it prior to putting the bolts back in you will hear an audible click as it pops into the cut out.
If you happen to have lost it and can't get a replacement I have made one before out of the spring in a disposable lighter which worked a treat.

Ok thanks a lot for your replies. Sorry it's been so late getting back I've had a lot of things to sort out.

My Feedback: (1)

buy new fuel! fuel does go bad over time no matter how you store it and that has been sititng too long.

Yeah I tried some new fuel before I got the engine into bits but that didn't work. All I need now is a replacement pin to go into the end of the crankshaft journal then i get it all back together and give it another crack! Anyone know where to get a pin from?!

Bump, anyone know where I can get a replacement pin which goes into the end of the crankshaft journal?
