its 26 years old and starts every time. the last time it starts but as soon as i back it off of choke it dies. cable looks good.. took the gas tank off so i could see all the linkage, but i don't know what its supposed to look like. i tied a wire on a lever which and i got some throttle action. it took a whole tank of fuel on just the front yard than cut out cause i think the plug fouled out from being so rich.
any ideas?
So engine dies when you move the throttle from CHOKE to FAST? That sounds like it has a fuel obstruction, perhaps slime / gunk in the carburetor.
But if the plug is fouled for sure, then it may be too rich, which can happen with a clogged air filter or blocked exhaust.
How fresh is the fuel? If you're not sure, I'd totally drain the tank and carburetor first. Double-check the spark plug and replace if questionable.
Probably NOT an issue with the throttle/choke linkage; here's what it looks like if you want to double-check:
