fuel tube in the tank

[C-Mac]

Hello all,


I recently put in my 29cc DDM in my MT and was sure that I had put the fuel tubes in the tank correctly but when I ws running it it seemed like it would stall. If i took the hose that does not have the clunk on it and pushed it further in the tank,for when I did this I could prime it again from the carb and it would run again. Is the tube without the clunk supposed to be pressed all the way to the bottom of the tank? If possible could someone post a picture of the tube length from the rubber stopper on the tank to see how far I should have it in please?


Thanks for all the help,


C-Mac

Hey C-Mac u don't have to put it all the way down in the tank. I think it only has to stick out like 1/2 inch or so into the tank, that's how mine is. U might have them crossed that's what it sounds like to me. Hope this helps Good Luck....

mine is flush with the gromet. it sounds like you have something else going on. is your tank venting itself properly? if its not venting and you prime it while its running it could help for a bit. check to make sure their is no pressure in the tank. also make sure the clunk is on the bottom of the tank closer to the center.

sounds like a fuel tank venting problem.

I second that.

Is there a remedy to the venting issue? How is it I didn't have this problem with the 23cc stock motor?

yes. you can open the hole on the gas tank and little bit, but the best results come with a vent tube coming off the gas cap. just pull the cap guts, install a barbed fitting and som fuel line. presto

Thanks Kryp and everyone. I'll try and drill the hole a little bigger first. Would you happen to have a photo of the vent coming off your fuel tank?

there is a small sump in the center of the tank I put my clunck in the sump. No more issues. Order of the lines makes a difference also! LOL
