A couple of curiosity questions about my 4910 I recently acquired in the Home Depot closeout sale: Is there a better fuel cap available for it than the one that requires a screwdriver/scrench blade to loosen it, hopefully one with two studs like the oil cap uses? I'm hoping something off another saw might have the same threads, as it appears the oil and fuel caps on this saw are not the same thread/size? Why use a whole different configuration between the two caps? Why in the world did Echo decide to use a nut to hold the sprocket and clutch drum on, on this particular saw? None of the Echoes I have, from older to newer, use anything other than an E-clip in this application - except the 4910. Usually I appreciate Echo's engineering, but these two things about the 4910 have me wondering "Why?". Just curious if anyone has any ideas. Thanks!
I have no idea. I wondered about the caps too. I didn't look at the threads. I know i have to use Scrench on oil cap sometimes too. I noticed that nut on clutch too. Seems Echo combines different designs to build a saw, the 2511T has external clutch like a Husky, the 4910 has internal clutch like a Stihl...
I've had a Husky flip cap on the fuel. Took it off bc it just didn't look proper. They both get tight in use. Baffling given the slickery nature of the contents. Maybe I'm just old & weak
I’ve never ran a stock 4910, but I’ve ran my buddies ported one a few times side by side with his stock Stihl 361 and my muffler modded 620P. It felt the fastest out of the three in the smaller wood, 620 seemed to pull ahead of the other two in the bigger wood but not by much. He’s got a second ported 4910 that I might buy. Do y’all think I should stick with the .325 it has right now or convert to 3/8LP if I do get it?
For what it's worth, I figured out today that the fuel cap from a 590/620 fits the 4910, and functionally matches the 4910's oil cap. I like that style much better so I wasted no time in ordering one. LOL
