Hello, I'm hoping I can find some advice here. Some time ago I was given my grandfathers collection of McCulloch saws and accessories, all of which have been sitting for decades.
Recently I've been wanting to get them running, so I started with the one that looked to be in the best condition, a 10-10 Automatic, and gave it a look over.
Still has great compression, piston looks mint, and it fired after 2 pulls with a little squirt of fuel down the carb. Only apparent problems is that the fuel line/tank leaked badly, and the pull rope has trouble retracting. It had also been sitting with old fuel.
Here's where my troubles begin. First, the carb: A walbro SDC. I decided to take it apart, clean it out, and put new kit on it since it had a lot of old fuel sitting. I took out the welch plugs too for a deep clean.
This went fine, except I realized after I finished putting everything back together with new plugs in place that I forgot to put a tiny mesh screen with a tiny C clip back in under one of the plugs. Is this a critical problem? I'd like to know if I can get away with running the saw without it, as the screen looked perfectly clean with no debris in it when I pulled it out, or do I need to start over just to get that tiny screen back in again?
Second, the fuel line: When looking into what to buy for this, I noticed a repeating trend of people complaining about the new replacements for the original rubber line not being the same quality and wearing out/leaking quickly. So I was interested when I noticed kits involving aluminum bushings that allow you to use standard modern fuel lines. I decided to give one of these kits a try.
Everything went together easily enough and the aluminum bushing pressed in without incident, but when I went to hook the new fuel line back to the carb I discovered a problem that I didn't think about, the original line has a flared out end to fit onto the carb.
I've tried hard to get it on by stretching the hose out a bit, it gets close but it just won't squeeze on there. Did I screw myself over here, or is there some kind of trick/adapter I can use to make this work?
See pic of what I'm talking about.

Any help would be greatly appreciated. I want to bring these saws back to their former glory buzzing through wood, but I feel like I'm stumbling along and failing from the beginning here, it's frustrating.
