Impulse hose for oiler

[mcycle12]

Like Karla48, I replaced the oil feed line with Tygon and it's been working well. The only line I had problems with finding a over the counter replacement size for was the impulse line. I was able to get a NOS part for that (without the spring).

I have 5 sizes of tygon 4040A and one of them I used for the splice within the carb housing ... just under the throttle linkage. But doesn't the tank have a big hole where it feeds thru? My line has a molded bulge in it where it comes thru?
I have not cut out the old line yet so I can't see the size of the hole. Did you have to epoxy or RTV the hose in?
thanks

Here's a bad quality photo of how the line is working on my 330. The saw had been sitting for several days when this photo was taken and there are no leaks.

To get the line in, I cut the end of the line on a 45 degree angle, sprayed some silicone lube on it and inserted it into the hole from the outside. I worked the end of the line into the hole using a dental tool, then reached into the oil filler hole with long handled needle nose pliers to pull it through.

Total time to complete, about 30 seconds.

Thanks for the pix. As long as it is a smooth hole and the hose is a squeeze fit like yours then I'll be golden...

I used a rifle bore brush and carb cleaner to make sure the hole was clean prior to putting the hose through.

Let me start off by saying that I've never had a serious chainsaw mishap in 40 years of cutting, that includes losing a saw. But there has to be a first for everything I guess, and in the grand scheme of things it wasn't all that bad. I did however lose my now beloved 330.

I was cutting a dead oak, one of hundreds on my property affected by the Oak Decline, when a combination of bad judgement regarding lean/top weight and a gust of wind conspired to make an 14" diameter oak twist on the backcut and fall towards me. The bar was pinched in the cut and I didn't waste time trying to free it prior to getting out of the way. Somehow the saw got under the tree when it came down. The result was not pretty. It reminded me of the Wizard of Oz, where the house was on the witch.

Now I'm searching for another 330. I do like the saw enough that I want another. It always started (something I can't say about my McCulloch Titan 50 when warm). I had my original saw apart enough times I can do it blindfolded, so the intake boot problem really doesn't scare me. There's not much to salvage on the squashed saw other than perhaps the carb and boot.
