any place to start with the screws...i was told to to 2 1/2 out on the top and 1 1/2 ont he bottom...this is where i am at...

any help would be great..thanks...

my guess would be the high end needle is too lean. whats the head temp? any trail of smoke?

Team Duratrax

Definetely too lean.Running it too lean will only make the engine starve of fuel when you gun it.

same for me but then when i rich it the engine turns off when i take the glow ingniter out you think the piston is worn? only half a gallon went in it though

and its a gx21

Team Duratrax

GReddy - Thats the most common symtom of a bad glow plug.

I highly suggest replacing your glow plug after an engine break-in.

the thing is that when i started having the problems i replaced the glow plug and its still happening

BUT when i put it on the glow igniter it glows bright red except the last coil on the outside

mayb theres something inside the engine? because after i get it started and i try to start it back up it feels as its flooded but its not

Temp the engine and see what it's at. If the temp is low try leaning it out some. It almost sounds as though it still to rich.

More technical info would help figure out your problem.

richen the carb up until the engine bog and splatters, then slowly lean the main screw about 1/4 a turn keep leaning it out until the engine acelerates smoothly, the smoke trial i have found is a myth, as some oils dont produce much smoke when burnt.

Greddy Id still say your engine fouled a plug. Its very common when you first start running a engine.

GregH

What glow plug are you using? What is the temp at when you have the problem? Will it idle without hitting the throttle? It can be to rich and shut off under heavy throttle. More info please.

Also, you mention it has a OS carb on it. They should be set at 3 1/4 out on the bottom and 2 1/2- 2 3/4 out on the top.

so even if it still lights up when put on the started, it could still be fouled somehow?

the 1st coil that you look at isnt lighted up

Team Duratrax

Its most likely your glow ignitor batteries man.
