Hello I purchased a MQ Power JF 200 clone. I had an extremely difficult time starting this engine whether cold or hot.
After reading I found that an idle jet drilled to 0.025 is the fix. Here is what I did and the engine starts very easily not and doesn't need choke or gas when warm.
Drilling was necessary for my clone to start correctly.
1st remove the plastic idle screw. If the air box or crank case vacuum hose are in the way, temporary remove them.
That plastic piece at the bottom is the idle jet. Gently pry it out with a flat head screwdriver.
The idle jet removed. A picture of it's side and underside.
A 0.0250 drill bit can be purchased at harbor freight if you search through the boxes. They also go by #72 as you can see. They are completely random so make sure that you can see it before buying. They sell in packs of 20 buts but I went through 6 boxes until I found one that had #72 displayed. Sometimes you can't read the bits size.
Drilling by hand is easy.
