Is there a carburetor on this thing, and if so, where can i find it?
The carburetor is between the air filter and engine... I think that model has a primer 'push' bulb on the carb...
There are 2 main reasons a 2 cycle engine fails to start or run..
1.. Poor fuel or wrong mixture. (most fuels today have ethanol, that evaporates out of the mixture quickly, Try to find no ethanol for your 2 cycle engines, OR only use premium gasoline for your mix.
ALSO fuel quality related, wrong oil mix... (too much oil will result in a lean mixture), not good as it will run too hot. and a too little will not lube correctly (and create a too rich mixture)...
2.. Poorly made carburetors, they are very sensitive to being exactly set and any change in fuel needs a new setting at the carb. AND they wear out quickly...
The real problem is The quality you can get for $75 is a bit suspect in todays market... It can be made to work but you will most likely have to do a bit of fiddling with the variables... KennyV
