Briggs & Stratton won't prime

[Fish]

What is the whole story on this engine? Does this carb have a choke? Is this a different carb from the original? What is the Toro model number?

Well it either primed by hand, has a manual choke or auto choke. If someone replaced the air cover with something they had on hand it probably doesn't have a primer bulb. Does it have a throttle control or govenor I'm wondering if someone replaced the carb at somepoint and got the wrong one. The prime hole is very obvious and should not be plugged

those darn filter housings will warp and also where it mates to the gasket will flatten out and it wont prime .....make sure its in good shape and replace it if need be good luck

I don't know the story on the engine. I bought the mower used a few weeks back. Not positive on the Toro number but I think it's
20487

Hard to say what's been done with a mower somebody else owned. It has a throttle, governor, and a primer bulb.

That part is NLA and with that hole plugged it's isn't going to prime anyway.
Since there seems to be some doubt here I'll post some pics. The carb # is 214570. Engine number 12f702-1814 E1 Serial# 97071659. This pic should lay to rest any doubt that the hole is plugged or was never drilled out:

This is the plastic "cam" on top of the choke shaft:

Is there a circuit in there somewhere where the green line is?


Heres the primer bulb and filter plate

That carb hasn't got a primer bulb, its fitted with a choke control. and the part number for carb is 498965

Well a pic is worth a 1,000 words, eh?

Ok... two questions.
What is that primer bulb looking thing where a primer bulb should be?
What controls the choke? Is there a part missing that fits on to of that cam looking thing that would connect to a spring or rod?
Ah hell 3 questions... if the carb is a 498965 then why does it have 214570 stamped on it?

Sure looks like a primer bulb to me.
Hell might as well ask another one
When the choke plate is closed the mower still won't start w/o gas or carb cleaner sprayed in the throat. How about just drilling that hole out?

Here is a pic of a choke model, just a blind plug/cap where the primer snaps in.

Well Toro 20487 is showing an ohv model

Looks like someone had an extra housing that just happened to be a bulb style... The choke should be controlled by the throttle you can manually close the butterfly with the throttle if you cannot it probably needs adjusting
