Have a homelite htc-12 tiller, it's hard to start and doesn't like to stay running. There is gas and oil in the exhaust and it loads the spark plug up fast. Don't know what's wrong with it.

No I don't need any help with this problem. I oiled it well and it broke free and works fine now
thank you

This could be one of several problems...
• Last year's fuel. Get some fresh gas.
• Every 2-stroke needs a new spark plug each year... you know what that means.
• Clogged carb jets due to storing the tiller over the winter with fuel in the system. Never, ever do that. Now you'll need to pull the carb apart and clean it. Most of the orifices are so tiny you can't see them. Good luck.
• Engine is so old the crankshaft seals have hardened with age. This is one reason no 2-stroke lasts longer than about 8 years. If the seals are shot, then it will cost more to fix than a new one costs. Time to toss it.

I had the same problem with my mantis. It would start fine after a few pulls, but had no power. I changed the plug, replaced the carb completely...nothing helped. Took it to a shop and paid $70 for a tune up that didn't help at all, and the shop owner just said "sorry".
After everything else was done, I pulled the cover off the muffler, (3 screws) then removed 3 screws over a small spark arrestor screen and found it was clogged...cleaned it and guess what...IT WORKS FINE NOW!

The best and easiest fix I have ever done to a small engine. I felt like an idiot, because the exhaust side of the motor MUST be clear to work properly on small engines. The only reason I was removing the muffler in the first place was to check the compression and VOILA!!!

An easy and quick fix I recommend for all Mantis tillers before you waste money on carb issues (which is what the company will tell you to fix to solve this problem).

SOURCE: looking for a primer pump for Homelite htc12 tiller

Hi, I live in cedar rapids, Iowa. I just bought a primer bulb for my htc-12 homelite tiller. You should be able to order as many as you need, but I don't have the part #. Find out what the part # is and call this # 1-319-393-0443. They have 2 sizes, the bigger one is for the chain saws, the small one is for the tiller.( they have both) Carefully pry the plastic band off the primer bulb, press the new bulb through the band, then go get a tube of permetex weather strip adhesive ( orange box, black adhesive). Don't buy any other brand!. Lay a thin bead around the base of the bottom of the ring, press into place and let dry for a couple of hours. This adhesive works on almost any thing, and is not affected by gas, oil, or anything.
