I am working on my second re-build of a Homelite 330, I removed the reed valve and boot. In completely cleaning, I noticed a small pin hole (maybe 1/16) in the corner of the reed valve compartment. Its definitely drilled into the casing. Does any Homeliters know why ? I also checked with a Dealer and he has a couple of these 1980 vintage 330's, and he never noticed it, but they are in his saws too! Any help ?  |

it might be the pulse hole. it lines up with a gasket and the carb hole

Good question.... There's a note regarding the C-9 and 91 to drill a small hole in the bottom of the reed cage on earlier units to "improve carburation". I ain't a fluid dynamics expert, so its hard for me to visualize what this would do other than maybe allow a little blow-back and pull a little air in addition to the reeds (very little). Maybe it adds turbulence... or maybe it prevents a puddle from collecting... not sure. Anyway, I have to imagine its there on the 330 for the same reason. I've noticed them before too. Hard to imagine a hole so small makes any difference, but somebody must have figured that it helped somehow.

Thanks Dan, I liked all of your reply but I'm kind of in favor of a drain hole to prevent a puddle.
Its all back together, my second Homelite 330 but minor problem it doesn't start. It definitely looks pretty though, I think I probably have an ignition problem, I did check it with a test lite and replaced the spark plug and the lite lights but not even a poof. So tomorow I'm going to check the start switch wiring and see If its grounding out or I have those two wires pinched somewhere. - Ugh. It definitely gives me something to mess with, Lol.

Dan, Just FYI - You were absolutely correct, I found an old service bulletin #181-014, which stated that a .040 inch hole was there to prevent a puddle, and that If the saw was turned on its side, it would flood the engine. So the solution was to put a hole under the reed valves. Again Thanks for your help!
