I have a friends T-REX 90 at my house and am having a little trouble with it.

It starts great and idles perfectly, but when you give it the gas it dies, any ideas on where to look first and what might be the culprit.

Thanks for the help ahead of time.

We have a T-Rex and had a problem with the same thing after we bought it used, we emptied the gas tank and flushed it with clean gas and changed the fuel tubing and that solved the problem. Not sure if that will help or not, we are currently having a problem with the tranny not wanting to down shift when going up small hills......any ideas on that one?

 

I had the same problem and it seemed to be bad gas or water in the gas. I put a heater near it for a couple of hours and then raised the backend up to be able to rev with out a load. Cleared out whatever was in there and haven't had a problem since. On a side note, I did have to torch all the baffles out of the muffler when I first got it to open the exhaust up. Before I did that it would barely get out of it's own way!

 

If it's not wanting to down shift on hills, I'm betting your rollers have flat spots. New rollers and a good clutch cleaning will get you back underway.
