When I start my inrerno dx it runs very good but after a half of the fuel tank engine stops and i then it takes me ages to start it again. And it happens about two times every one tank. What can be wrong ? Help please!

hi how old is your engine it sounds like lack of compression when the engine is hot(as the sleeve expands).that is my only idea which you can only solve by buying a new piston and liner.

Oh it's preety old ... it's 5 years i think ... but at first i didn't run a lot.... but for a year i've been running much more.... btw, i need to buy a sleeve and a piston or sth more ?

Anyway thanks a lot for your reply ! ;-)

Also check for any holes in the fuel and pressure lines.

I checked fuel lines and there is a small leak in fuel filter... can it be a reason that engine stops ?

You said it heats up and boggs down and dies until it cools down? Thats definitely "Blow by", meaning its time for a rebuild or a new engine. Try replacing the fuel line, but I doubt thats the issue if the engine is indeed old.

Ohhh yes!

edit:
I bet you $5 (of imaginary money) that it runs after you fix that leak.

OK we will find out when i fix it tomorrow.... ;-)



i though about rebuilding the engine so anyway i'll have to do that .... i see

When the engine stop...? When you accele or stop or in the coner.

Buy a new gasket set for the gas tank the seals could make the engine die at half tank that is what happened to me

rwong21: when i stop and in the corner when the engine is on low rpm, always after lots of accelerations.... when the engine is very hot

BEEN THERE WRECKED THAT: where is gasket in fuel tank cause i don't see any ? :/

Sorry all but i forgon about sth ... when i changed muffler pipe for the ne one it hindered me to tighten the manifold ... i need to fix it right ?

Also, how is the clutch internals looking? possibly a prob there too if it happens on deceleration.

Two week ago I had this problem. To fix it please check the following:
1.- Take off you air filter.
2.- Check in the carbulator how many space you have in the neutral position.
They more often need around 1mm to 2mm of space.
3.- Press the break and see how many space you have in the carbulator.
Check it carefull....if it have a litter space for example 0.5mm ....this is the problem.
for increase the space or rpm.

Maybe you want to know how to adjust the rpm and something...please check the following link ...Two guy help me alot.
You can find all information. I give you a summary in the above three step.

When you taking about the engine is very hot. This is another reason the engine stop.....because the engine cannt receive a lot of fuel.

My suggestion is fix one problem and after to check another one. To fix the the engine is very hot is try to rich the HSN. You can see in the pix of the link where is this screw.
