how does it know when to open? will the carb choke if i dont pump the gas down before i start it? is there a way to make it open sooner? it sucks having the choke take so long to open. secondaries wont open untill the choke is completely open. also it seems that there is more noise from the mechanical fan while the choke is closed. is the fan clutch a heat thing too?

 

The electric choke is a heater element shaped like a coil that twists when it changes temperature to open and close the choke. You can rotate the choke housing to change the tension on the coil to make it open faster or slower. You do have to pump the gas to let the choke snap shut before a cold start.

On an 84 you probably do have a thermal clutch fan, the fan hub will free-wheel to save power until the air coming through the radiator heats up.

 

Currly: Ya a heat ting . dats da ticket, a heat ting.....

Mo: YYYY I oda!!!.......


WOP WOP WOP WOP WOoop......

 

"On an 84 you probably do have a thermal clutch fan, the fan hub will free-wheel to save power until the air coming through the radiator heats up." True, but first thing in the morning when the clutch fluid is completely cold, the fan will pull lots of air for a while--it's a viscous clutch, so cold equals more friction and more fan speed. The older the clutch is the longer it will pull air until the fluid gets warmed up. You don't want full throttle anyway, until the engine is fully warmed up(not very nice to the engine). Also, you don't want the choke to open too quick--it won't stay running. If the engine is running OK when cold, the choke is probably adjusted correctly. Full throttle on a cold engine is the wrong reason to loosen the choke.

 

i dont want to full throttle the cold engine, its just annoying to have give it a lot of gas to go nowhere when its cold, and it feels like its harded to rev when im driving untill the temp gets up to where it normally settles, which is right above the 160 mark. also the fan displaces so much air you can barely hear the damn radio when its cold. thanks for yalls help.
