T-maxx starting?

[mike250]

I bought a T-maxx like 5 years ago and it always is a bitch to start. Why is that? When the truck gets started it runs great. I use the gas they(hobby shop) told me to and the rite glow plugs. Now it wont start at all. The fuel turned into a jelly and has cloged up the fuel lines.

If the fuel jelled and clogged up the lines it probably clogged the carb and maybe even the motor. You might want to pull the carb off and the starting plate and clean them out. As far as the hard starting i have no idea. Ive had alot of trouble starting nitro motors. Good luck

If you left fuel in it for that long, you need to take apart your entire engine and carb, clean it VERY well. Get a new tank and lines also. You might have to get a new engine. After running a r/c for the day, drain any leftover fuel from the tank and always put after run oil it in.

BTW if it's the old TRX engine, you are better off just getting a decent new engine for like $150.

As for the hard to start, it was maybe a tunning problem. The old TRX engines are very picky. I went through 2 of them before i bought an O.S. engine. There also can be a number of reasons. If it runs fine after it warms up, id say just leave the carb alone.

I dont think that leaving gas in the thing will warrant needing a new tank or lines and if you clean them out really well they will be fine. The motor wont need replaced either unless you just want something better. You could pick a newer TRX motor off of ebay for pretty cheap. It should all be fine after a good cleaning. You might want to make sure there arent any air leaks and seal the carb up good.

I'm thinking of maybe getting the 3.3 motor..Is it alot better then the old one?

I had the 3.3 motor with paddle tires on and it was so fast in the sand it would beat alot of quads in a race lol!

what fuel were you running those little motors are real picky on what runs & what runs real good & easy to start be sure to store you fuel in a cool dry place the fuel is over 50% alcohol & alcohol is hygroscopic (absorbs moisture) wet alcohol even with 20% or so of nitro is still hard to light so clean it out & get a good fuel i've had good luck with o'donnell it's a good high quality fuel unlike cheep t-max fuel & several others

3.3 are monsters compared to the first TRX pro engines(before the 2.5). If you go to the tmaxx site, you can see it in action.

Rich is right, you wont need new stuff if you clean it out. I dont know why i even said that. I'm just lazy heh.

If you turn that low-end screw out about an 1/8th of a turn you'll probably start alot easier. Use that "reccomended" fuel to clean everything up with, then get some O'Donnell 20%. OS glow plugs and Duratrax Platinum are what I use and they last close to forever. They start the engine a hell of a lot easier than any other brand I've used.

im going to get a 3.3 and start from scratch
