Went through the steps of things to do and go it starting!!! Thank you very much for the info.

Hopefully 1 last question for you. Idling seems a little rough but nothing crazy. When I hit the throttle the exhaust makes loud pops but stops while idling. I checked the exhaust and saw the pipe was undone from the engine. I put it back in place and tightened it down but the popping noise continues. I did not see a gasket/seal for the exhaust - is there one needed/missing? The exhaust is rusty - maybe there is a hole somewhere?

Was planning on possibly replacing the exhaust but have not really found a site for exact replacement - not sure if this would be the best option. If so does anyone know of a site to purchase a replacement exhaust?

Bad spark plug maybe?? The popping noise/smoke appears to be coming from where exhaust goes into motor which is also near spark plug.

 

Glad you got it running. There should be a sealing ring between cylinder head and exhaust pipe. Sort this out, treat it to a new plug, and use the bike for a while before trying to alter anything, often a bike that has sat a while needs time to settle in to running again.

 

Is this normal - half of the 1 side missing? It looks like a piece has been cracked off. What would the seal look like for this?

If this piece is damaged whats the piece called so I can replace it? Thanks

 

Here are other pics os the replacement piece needed - silver piece all the way to the right and to the left (same piece different views)

 

Shouldn't the 1st pic look like this in regards to exhaust connection

 

Recon you last pic is the inlet side of the cylinder head. Yes, there may be a bit broken off, but there is a complete circle of exhaust port where the sealing ring sits, and the two stud holes are OK, so the broken part doesn't matter a bit. Get a sealing ring and fit it.

 

Would this be what the sealing ring looks like?

 

Could be, any I have seen for the Honda Cub clones is like this https://www.ebay.co.uk/itm/Seal-exhaust-around-35x43-5x5-3mm-Honda-Lead-100-SCV100-08/291967647080?fits=UKM_Make%3AHonda%7CUKM_CCM%3A110 &hash=item43faa0bd68:g2kAAOSw5YNZt5s1 but may just be from a different manufacturer.

 

So I adjusted the carb and the popping noise when the throttle is pressed stops. Only issue now is when I start the atv it seems to be idling ok. When I hit the throttle then let off of it the atv rolls forward by itself without me touching anything. Could a high idle be the reason?

 

Yes, you need to set the throttle stop screw as slow as possible without stalling. It will rise a bit as the engine warms anyway, once off choke.
