Difficult starter

[seanmc1970a]

Starting on my winter van jobs whilst its off the road for winter. So thought I'd address the starting issue. I can get it to start okay, I pump the accelerator 10 times turn the key whilst still pumping and I give it fuel until it warms up.
Then its okay, occasionally I get the odd back fire and loss of power, but a good revving for a few min seems to solve this.
Sorry I'm not mechanical, learning though. Any thoughts on improving this.

Thanks Sean

Usual cold start technique is to push accelerator twice (this pumps a little petrol into the system but more importantly it resets the choke flap to the start position); then take foot off the accelerator and start engine (with foot still off the accelerator) - engine should start up and idle.

(Keeping your foot off the accelerator ensures that the choke is correctly positioned - pumping the accelerator during starting is going to open/close the choke which is not going to help you)

And it floods the engine with excess fuel.

You'd think it would flood, but seems to need the pumping to get enough fuel in there, if I just pumped twice theres no way it would catch

Then check the choke flap is setting to the closed position.

Thanks BigHerb, will have a look when the weather improves

Rain eased off so popped out for a fiddle before Sunday lunch, choke flap not closing. sprayed with GT85 and gently moved it and seems to be freely working.
Two pumps on the accelerator and hey presto.........Many thanks

Now onto the dash PCB.......bought one from Brickwerks
