ok, the engine runs fine for about 3 min after that it 'll cut off and die, is the carbb still dirty?

does it have gas in the tank? good gas?

No industrial motor is anywhere near as sensitive and temperamental as a microscopic Honda scooter engine.

You've obviously never used a 50 year old JAP 2 stroke then!

It runs when it wants to, no one knows why lol

how do you know if the engine is running rich???

how do you know if the engine is running rich???

Black exhaust fumes and blackened spark plug.
If everything is correct, center electrode porcelain will be a tan/brownish color.
Lighter color equates to lean
Darker color equates to rich.
I can tell if a rich condition exists by how much my eyes burn...or the stink emitted (more hydrocarbons).

yeah, but it does this every time.

i think i'm running rich

 

[freakboy]

it might be running rich then bogging down cause to much fuel? try screwin in your mixtures on your carb a little bit more.

 

[briggy]

ok, i thought so too, but i'm confussed now, cause after it cut off it won't start like its not getting fuel, maybe the carb is still dirty..

 

[Russ2251]

Try to start with dry plug.
If does not start in a few tries, check plug to see if wet or dry.
If dry, there's an induction problem.
If wet, there's an ignition problem.

 

[briggy]

yeah, checked and its not getting fuel, i'm thingking maybe i'm doing something stupid:S i'm using a bottle as a tank, do i have to put hole in it??

 

[Russ2251]

Yes, needs a vent.

 

[briggy]

yeah, i think that was one of the problems

 

[freakboy]

that would have been your problem then it creates a vacume and then starves for fuel....u didnt notice your iv bottle colapsing in on itself?
