Thank you sir for your input 👍 Did pull the plug and checked for spark, and it's nice and blue. I will spray some starting fluid into the carb. I didn't know where I was to spray it, so thanks again for the tip. Any thoughts on the loud, grinding halt that happens after it tries to start? I haven't found anything online that sounds similar. Could it be something located in the head, or cylinder? I know my engine is not seized because I can crank it by hand. I have a short audio clip I will try and post
Would anyone mind providing me with their feedback? Backstory: I recently purchased (2) 2006 Yamaha Vino 125cc with 40 original miles, that had been unridden and exposed for the last 13 years. Foolishly I thought buying them would be a great idea. It's been a nightmare but I've actually been able to get one to turn over recently, albeit for a moment before a very loud grind/clanking noise occurs. I am able to spin the flywheel by hand, and the Kickstart is not locked up, but making a whooping sounds, like gasping for air. I can also feel a pulse of air from the cylinder when starting without the spark plug so I do not think my piston is seized. I refuse to believe it, although it could very well be the case.
Here's a link to a video I made trying to start the engine after changing the oil, and bypassing most of the electric starting system due to corroded connectors, etc. Been on it for about two weeks. Lots of gremlins, lots of frustration.
