warm start issues

[sparrow61]

having trouble with engine warm start, running with a jetex 22 mm carb settings being 45 pilot 50 choke and 123 main. She kicks over without choke on a cold start but gives trouble when kicking over when warm.

what CC? What state of tune etc?

Someone on here sugested a 1mm hole in the rubber inlet from the air filter - tried it at the lowest point and it seems to cure any warm start issues with a Jettex. Only drawback is the fuel which is normally spit back, being deposited on the inner floorboards

you could retro fit a tube as per the old type rubbers to direct drain below say fan cowl.

Sounds to me , you have a problem with your choke not closing off.

you should really need the choke to start from cold....

other warm non-starting causes can be:
fuel filler cap blocked
plug gap
worn rings
something electrical breaking down

Warm starting issues with points ignition is often indicative of the condenser breaking down, but you don't give us enough info in your original post.

Is it points or electronic?

Agreed, thats the first and easy,st thing to check.

thanks lockman69 have checked the choke out today and found a small burr on the choke jet , this i have dressed. Have taken the lammy out for a run and everything seems better when kicking over on a warm start fingers crossed it stays like it.
