026 won't fire on choke

[Dan Forsh]

Hi,

 

Anyone got a clue why?

 

my trusty old 026 has been shelved for a while, but was needed this weekend so I got it out added fresh fuel but it didn't want to pop on choke. I put a little mix over the back of the air filter and it fired straight up and ran fine thereafter.

 

However, from cold it still won't prime from choke and I have to do the fuel on the filter trick again.

 

I know these can be a problem sometimes with the choke flap not seating properly, but I checked the position by marking the little lever with a pencil line and it shows it is fully closed when the control lever is set to choke, so I'm wondering what else it might be? I put a new impulse hose on this not too long ago, so doubt it would be a lack of pumping by the carb, unless it's the carb diaphragm needs changing maybe?

 

Saw runs and idles fine, just this cold starting that's a pain.

 

Cheers Dan

Is the fuel filter a bit tired/blocked.?

I think I also changed that not too long ago, but it's an easy one to try, so I'll replace the filter. Wouldn't a blocked filter cause running issued too though?

It could be that the choke isn't sealing well or that the throttle isn't being opened enough on start up. A carb tune may help also - difficult to tell without seeing it.
