Hey all!
I have a 2010 CubCadet weedwhacker/trimmer that I fixed this past winter that's been out of service for the past 5+ years. This used to be my father's favorite trimmer but the upper driveshaft housing/tubing broke where it snap/clicks into the lower housing. He stopped using it for a Hitachi WeedWhacker/trimmer which I got one too and they are nice and durable!!!
He said I could have the CubCadet and we both had the idea to lend it out to people who could use one. So I fixed it over the winter and decided to give it its first test today.
Well, it ran rough, and could basically only idle, emitting white smoke (could have had blueish tint but I didn't really take special note). Whenever I applied throttle it would increase RPM but the whole trimmer would violently vibrate/shake, and if I gave it enough throttle it would completely stall out.
I thought it was due to old gas so I let it idle out until it stalled from no more gas. And so I put in my two stroke gas in it but it still ran the same. Idle pretty rough, violently vibrate/shake with a little throttle, and stall out with a lot of throttle.
The head does spin freely, I even disconnected the head of the trimmer and rotated the driveshaft with my fingers and could feel no clear resistance or jumps/skips etc. Rotating it by hand it was smooth.
My two stroke gas did sit over winter but my Poulan Leaf blower, Hitachi string trimmer, my restored 2000 Barracuda Weed Eater, and my chainsaw all ran fine on the same gas.
The gas is 87 octane and ratio is 50:1. The CubCadet calls for 40:1, haven't read the manual yet if it called for higher octane. I didn't think there would be too much harm or difference running 50:1 in it just to see if it could trim some lawn edges so I'm here asking you guys what could be the potential issue?
Should I take the spark plug out, sand it off a little to see if there is even a minor amount of improvement?
Thanks for the help!
