Hi All,

Been looking through the forum for a while now and figured out I have a SB 45 with a pulsa crab. Thanks for a great resource.

I’ve decided to get the old girl back up running again, so far I’ve replaced the diaphragm, and the gaskets between the carb and tank and carb and engine.
She won’t start, if I remove the air filter and drop in some fuel she’ll start and run fine. If she then switches off she’ll start after 3 or 4 pulls. But cold no chance, once I get her going I put the air filter back on and she carries on going.

Sounds like a choke issue? When I move the lever to start, with the air filter off I can see the piston for the choke move and leave thin slits.

Is there anything else I can check?

These are the model numbers that I found on her:

0879 01 81110303

80202

Thanks in advance
Cheers
