I just bought a brand new QIYE Coolster 110cc. Just assembled out of crate last night. Charged battery, went to start & only cranks. Checked fuel is getting to carb and it is. Fuel filter I found to be upside down so I flipped it around. Tried starting it for like an hour & got nothing, only cranks. Checked to see if getting spark & I am.

Please help!!

 

Welcome to the forum kalani808!

Is gas getting past the carb and into the engine? I would try spraying a little starting fluid into the catrb and see if it fires. If it does youve got a plugged jet or needle valve in the carb.

 

I have tries starter fluid in air intake, Also spryed directly into spark plug hole. I feel gas come out of spark plug hole. Spark plug is also wet. I'm getting spark, checked that by placing the plug to the block. I also took carb apart check any blockage in jets & made sure floats were working. I AM SOO FRUSTRATED!!!

 

hmmmm...Is the spark blue? are you still using the stock plug? NGK C7HSA is a good replacement..Ive seen some plugs fire outside the engine and be dead under compression.

 

Yep spark is blue & tried a NGK plug too. I'm stuck!

 

Compression Im guessing is good? Valves that are too tight will keep a engine from firing... not likely on a new unit though..

 

Not sure about valve, but can feel compression when I put finger over spark plug hole. Wierd that it wont even fire off! UGH!

 

Id think its either a timing problem or the valves need adjusting... Weird that it wont even pop though... thats why Im thinking the spark is happening at the wrong time...

 

Think I should mess with it anymore or try to return it, this sucks! Is there an easy fix??

 

How much of a pain to return it?
