Unhappy Homelite Blower / Vac died

My Homelite HB-180V Blower / Vac died today while I was using it and it wouldn't start. I checked the fuel lines, filter, wires, etc. all are good. Its getting spark and will fire if I put gas in the cylinder.

I suspect something is the carb is plugged because:

1. After pulling the starter many times I removed the spark plug and it is bone dry.

2. I removed the carb and pushed the primer bulb and no gas came out of the carb. I removed the bottom plate on the carb and gas flows though that when the bulb is pushed.

It was running ok right up until it stopped although I did notice the the spark plug was loose when I went to take it out.

I love this little blower / vac and they aren't made any longer, I'd like to keep it alive a little longer. Thanks for any help!

When you prime the primer, does gas circulate through the carb and return to the tank through the return line? I think you're right about it being a fuel problem. Is there a crack in the primer? How long since the fuel lines, primer bulb, and filter have been changed?

Good Morning,

Yes the gas flows through the return line. The fuel lines were changed last year and the primer bulb has never been changed. This was running fine, it would always start 1st or 2nd pull, even in winter. It just stopped and wouldn't restart. It didn't make any significant noises before it stopped, just started to sputter, slow down and stopped, I thought it was out of gas but it wasn't.

When I remove the carb and push the primer should I have gas coming out of the jet? I don't.

I did a little more playing with the blower motor today and the gas is not getting through the carb even via the priming bulb? I checked the diaphram and it isn't broken. Since it stopped suddenly it obviously is not an adjustment (it was running fine).

I don't have a compression tester so is there any rule of thimb way to determine if there is enough compression?

Any thoughts on what to try next?

Just pull the spark plug, & with the stop switch in the "OFF" position, Put you're thumb over the plug hole. Does it try to suck it in & blow it out ??? It's not verry accurate, but you get the idea at least there is compression!! Roger

If fuel is flowing out the return line, then it is going throguh the carb with operation of the primer. There should never be any fuel to enter the throat of the carb when you push the primer if that's what you're looking for.

I suspect you have an ignition problem or lack of compression.

Hi Hopkinsr2 & Cheese,

I took the carb off but kept the fuel lines in the tank. I pushed the primer and no gas comes out of the jets on the back of the carb, should it? (there are 2 holes, one above and one below the throat of the carb. I assume these are the jets that the fuel comes out of, correct?)

I have some compression (the thumb test) and I have a spark. If I put a little gas directly into the cylinder it will fire.

Found it.

While I had compression but I didn't have any vacuum. There was a loose screw that attached the crankcase to the cylinder. Tightened it down and we're back in business.

It was back behind the gas tank so I never saw it until I pulled everything apart.

Thanks for the help.
