120y van starts really bad, like is getting too much fuel and blue smoke

[Telepizza]

Helly guys, i have a 120y and first start is like is getting too much fuel and need to rev it to keep it running until heats a bit and stays running. And i get blue smoke. Is my engine dead? I notice a white box near the suspention that plugs the front lights getting some sparks aswell . Need help if i need to change my motor 🥲

Is this a new vehicle to you? Or you've had it a long time and this just started happening?

 

Hard running when cold starting could be the choke is not working. Next time it's cold, take the air filter housing off and look. Watch while someone steps on the gas. You should see the part open choke flap snap closed. 

 

Blue smoke puff when starting cold or hot restarting could be the valve seals. Seals are a couple of dollars each and half a morning to change.

 

Blue smoke most of the time and specially when slowing down is worn rings. Only a rebuild will solve this.

Brought it from a colleague, i have 2 more engines, another is fresh rebuilt but after i did a 150 kms drive started doing this. This have still power and after is warm gets way better, just the cold start is a pain in the arse, looks like im killing it and i dont like that. That white box i refer myself does some spark because the front lights dont light up until i touch the wire in one of the pins.

So which engine is in the car now????

 

 Have no idea what the 'white box' is. Post a picture maybe I know it as something else. What type of headlamps are in it?

a 120y is like a b210, A series engine I bet

Is a b210 . Is a 120y van

One thing i remember aswell is i changed the gas filter for a bigger one. Can that be the case of making the car choke like at cold start? As the original ia a small plastic filter?

hard start make sure intake tight, carb bolts tight

maybe compression check to make sure valves are closing all the way

 

water under distributor cap.

 

if still using points igniton make sure points adjusted
