Hi I have a 18hp twin v vanguard engine attached to my max 4 6x6. I was repairing a broken chain yesterday and when I finished I rode it around for a second. No problem starting at all. When I turned the engine off and tried to start it back up it started for probably 3 seconds and then stopped and hasn’t started since. I haven’t been using the starter to start it because I am waiting on a new gear so I have been using the pull cord. I am not very good with engines yet. The spark plug had carbon build up on it so I replaced it. I charged the battery. I cleared the air filter. Everything I do doesn’t seem to work. If you have any advice that would be great.
Thanks in advance.

if you have any starting fluid or parts cleaner or other combustible substance, put about a tablespoon, or 2 or 3 short spray bursts into the intake... remove the air filter... try to start... if it runs the dies, fuel delivery issue..
if the carburetor has one of those Anti-Afterfire valve on the bottom of it, that could be the culprit. you generally hear a slight click when you turn the key to ON, coming from it.
Also post up the Model and Type numbers.

whenever I pull the chord it sounds like it’s trying to pull something in but it’s just getting air
