My neighbor brought over his Dinli Dino 50cc 2 stroke atv for me to fix and I am having some problems getting it figured out.
I can get it to start on starting fluid with the carb off but with the carb on it floods the cylinder almost immediately with fuel and will not start. If I air/dry out the cylinder I can get it to start again with starting fluid. I was advised that a new carb would solve my problem so I purchased one but, while it couldn't hurt to have a new carb, it did not solve my problem.

Do you have any suggestions on why the cylinder is flooding with fuel and what I should be checking ?
Is there a way to disable the electronic choke to try and start it without it ?
I am not sure how the electronic choke works or can I test it to ensure it is working correctly ?
I am also unsure if the new carb comes preset or do you have the starting settings that I should set it too ?

I should also state, I tried checking the float and it appears to be working properly. When I manual put a small amoutn of air pressure in the fuel in hose if I lift the float it will shut off the air. So I think the float is working properly.

I appreciate your help and any suggestions you have for getting this atv running again.
Thank you.

 

I recommend that you call/email Maximumrpm.com.
Justin was the original importer of the dinli and I'm sure the fine ppl there can help you.

 

while he has been helpful with his suggestions, his ideas for fixing it has not helped the problem.
