Primer bulb wont prime!

[18 stoner]

To be honest, the saw should run without the primer, that just makes it easier to start.

Without it you need to pull it over a few more times so that the impulse operated pump can pump some fuel up.

Some carbs I buy have a little cap to block the brass pipe when fitted to a machine without a primer, which is what yours is now.

I will check tomorrow to see if there is an alternative and let you know.

 

Cheers for that, never really thought it could cope without really, but as you say, no reason why not once primed.

 

Only trouble is, it is possible to start it after a while on full choke, but it simply wont run right and starves itself out when you take the choke off.

 

Could you not try to break up the blockage with a needle or fine pointed tool?

 

I have tried with a fine piece of copper wire, but the brass pipe itself has a 90 deg bend in it that makes it very difficult and from the inside its very, very small and cant tell whats its butting up against when you are 5 or 6mm deep.

 

I soon gave up on this, as didnt want to do irrepairable damage:blushing:

If its a brass pipe would leaving it in a strong cleaner not break the blockage down??

Tbh Richard, if the ultrasonic has'nt shifted it, no cleaner will.

 

Probably best to have a new carb now, with these running problems. Maybe the dealer who has not fixed it should have it back, I know I would want to.

 

By the way Rich, your package arrived Sat, will be off to you tomorrow.

I have checked with my carb specialist and unfortunately there is no 'after market' carb for your machine, only genuine. The S103 has been replaced with the S134.
