205 Rallye Starting Problem

[fliprio 9]

Hi all,

 

My 205 Rallye has been sat outside for the past 4 months and now refuses to start, its always started even when its been cold and left for weeks so something isnt right.

 

It spins over nicely, but wont fire. The old plugs looked a bit worn so its got a new set of plugs.

 

When turning it over for around a minute, I wipped out a plug and it looked to be dry (always seems a bit difficult to tell on new plugs).

 

There is fuel going into the carb from the chamber bolted onto the carb body, so its getting fuel from the pump, any ideas why its not then actualy getting fuel into the inlet manifold?

 

I take it a minute of cranking should be enough to flood the engine and make the plugs nice and wet? It usualy starts from cold, with a little or no choke, foot to the floor and then pull the choke out when it fires, but choke in or out, foot down or no throttle it doesnt want to play ball!

 

Cheers

Dan

You can do it if you have the window open and have long arms!

Take the air filter off so that you can see down into the carb. Open the throttle and see if you can see the accelerator pump squirt a load of fuel into the venturi. If not, it could be that fuel is not getting through as you suspected.

If you do see a squirt of fuel then it looks like the problem lays elsewhere.

 

Are you using the choke!? :-)

I found it had a spark, but after testing the spark, it magically fired into life

 

But after 2 weeks of turning it over it seems strange that it suddenly fires, unless the sunshine this week had dried the HT leads and it only had a weak spark.

 

I find the choke a bit fussy, it normally starts best without any choke, but pulling the choke out just as it catches and then running half choke, but tried it all different ways over the past couple of weeks.

Certainly sounds like the carb would benefit from a rebuild, have you thrown any carb cleaner down it recently? I've found that stuff can really help.
