Hi folks. Any advice would be greatly appreciated. I have a nearly new Tanaka THT-2120 that I've used twice. Started and ran fine those times. Last use was about 5-6 weeks ago. Went to use it today and wouldn't start. Using the same fuel mix as in my Stihl trimmer and blower. Stihl 2-cycle oil w/ stabilizer. Pulled, cleaned and regapped the plug, wasn't very dirty from such limited use. Darn thing won't start for nothing. Cranked it over and over and over. Any ideas???? Thank you.
