Lawnboy 2 cycle carb question

Posted by greendrake SW PA (My Page) on

I have a 1994 Silver Series 10201, SN 4983731. I can't remember the circumstances but after I owned it for a few years, I had some sort of problem with the plastic cover/fuel tank and the dealer gave me a used one and a carb. to go with it. My original mower had a primer bulb but I ~think~ the "free" replacement did not and that's why he gave me a carburetor to match the primerless cover.
Anyway, this thing is a b*tch to start and I'd like to go back to the original setup.
My question is: What does the primer bulb tubing connect to?
I have bought a new cover/tank which I probably didn't need and also a primer bulb assembly which I did need and will probably fit on the existing cover/tank (there is a little hole for it). Does the primer bulb pressurize the fuel tank? Or does it send fuel to a second port on the carburetor?
Thanks, greendrake

In general, all the Lawnboy primer bulb equipped mowers I have had (and I have had plenty) pressurize the carb float bowl, causing a squirt of raw gas into the intake of the engine.

So the tube from the primer bulb connects to a port on the carb? I'm trying to find out if I need to replace my current carburetor. I don't think this replacement carb has a port for the primer.

The 10201 had a Walbro carb. The Walbro needs a bowl fixing nut with a hose barb arrangement in order to use a primer with it. These are very hard to find today. The Walbro should have a choke position though and if it's clean and adjusted properly, should work fine.

Thank orangedot.
>and if it's clean and adjusted properly<
I'm due for an end of season overhaul. Once I get all the crud off the carb, we'll see how she runs.
