Just inputting....

His bike starts when he primes it through the air cleaner.

Well, I'm thinking it's a vacuum issue.....unless worst case scenario no compression which would lead to fuel NOT being sucked into the chamber....

You can have air, spark and "fuel" but if compression is missing then fuel won't be drawn in. I believe starting fluid is easier to ignite and since it is more of a gas it is sucked into the cylinder easier....

What does your plug look like?!?!?!

You said you reconnected all hoses, but I just want to verify because there is an easy one to miss. It starts on the right side of the carb, travels in between it and the engine, and connects on the back of the petcock. It provides suction to allow the petcock to deliver fuel. This would explain why it works on PRIME but not on ON, as PRIME bypasses the requirement for a vacuum line. Unless I'm misunderstanding and it isn't starting on PRIME.

Although, I don't know why it would die on you at 35mph...! Sounds like fuel starvation either way.

Another user took a picture-- it starts behind the throttle cables:

You should be able to feel either the hose or the empty nipple if you reach behind the petcock!

Yep reconnected all the hoses sorry about the late reply changed ignition coil still nothing... I think it has no compression at this point I'm looking more forward to selling it and buying new

Just listened to the vid again. It sounds like it has compression as it turns over. I agree it is a fuel or vacuum problem but how did it happen so suddenly?

Sounds like you have a tank full of mung or rust. Probably will do it again. Just scoot down to an auto parts store and buy some Seafoam. Add the appropriate amount to a full tank and ride it. Repeat if needed.
