ok i have a cen tr4-4wd i just had it fixed and i went to take it for a drive. but i sorta drove it on a baseball feild n now everytime i pump the gas in it sucks it back out. plz i realy need some help with this

im guessing u mean that when u go to prime the engine, the fuel runs back into the tank?

if so is this just when the engine is hot? mine does that sometimes and all i do is let it cool for a bit then try again

i believe its due to the heat of the engine heating up the carb.

thnx allot for repleying but it is doing it cold i havent been able to turn it on

I am having a similar problem with my son's ATX after he ran it on a ballfield last weekend. We have been there several times before, but last weekend it was pretty dry and dusty. It started running really rough and got real hard to start. I took the filter off and found some dust had gotten past the filter. Last night I took the motor partially apart in fear dust had scratched the cylinder up. But it was good. I do not have a problem with the fuel returning down the line, but sometimes when I try to start it I cannot get fuel to go into the cylinder. I can cover the exhaust and pull it 15 or 20 times and it will not load up. So I think my problem is either a clogged up carburator or an air leak somewhere causing it to run lean. I took the adjustment screws and filter off the carburator and cleaned it out pretty good. I am going for new fuel line tonight to see if that fixes it. Also, my problem is worse when the motor is hot unlike yours. I would start with new fuel lines and look into the carburetor to see if anything is loose or clogged. Just my 2 cents.

thnx allot for the reply you explained it exactly as it happend to me, im gona have to check that and try it once this stupid hurricane goes by thnx again.

I once was having similar problems and I found the fuel filter seemed to be the problem, its worth a shot to take it off and see if anything changes.

thnx, i guess il look up where the fuel filter is cuz i cant really remember seeing one

Probably doesnt have one as standard, so if you didnt add one then there probably aint one there!

lol that may be why i didnt remember it thnx anyways

It kind of sounds like somthing might be blocking one of the passages in the primer bulb.
Blow into the fuel line and see if you can dislodge whatever might be blocking it.




rolland

just don't suck on the fuel line !!! thats a newbie mistake

srry i didnt post earlier there was no power because of this damn hurricane it does nothin at all to the house or any house around yet the power misteriously goes out. BAck to the subject yea thnx i cleaned the tubes no i didnt suck on it i took them completly off and i cleaned them they had a little dirt in them i havent started the engine because there are to many puddles and its still raining every once and a while
but i was able to pump gas into the engine so it should work(i hope) well thnx for all your help.

ok forget what i just said the gas is stil not pumping into the motor i think im going to have to take it to the hobby shop unless someone has a better idea i checked everything the carburater, the filter the tank itself, i put some fuel were the glow plug is, etc.... if anyone has had this problem before plz tell me what you did to fix it anything at all will help me plzzzzzzz.
