Have an MTD weed whacker, 4 stroke, that I bought years ago. Fixed a fuel line this summer and fired it up for the first time in a couple of years. Ran good for nearly 10 minutes then lost power--would idle, but would bog when I hit the gas. Hit around the spark plug area with my new toy from HF, the laser heat gun thingie, and it showed a max of 288F. Any chance it just overheated? I haven't had a chance to try out again just yet.
Fresh gas, although plug and oil are getting old.
