Question about Troy Bilt Tb70ss Gas Trimmer
You have all the elements of a running engine. Final items to check:
1. Muffler. Can become clogged with insect homes or carbon deposits. Restricts back pressure and it will not run or will run poorly.
2. Your spark could be insufficient in which your Ignition Module/CDI would need to be replaced.
3. Insure that the 4-screws holding the carburetor holder / lower crankcase are tight and that the gasket is in good condition.
4. Spark plug gap may be too large.
Insure the engine will run by putting about a tsp., of premix down the spark plug hole and pull over. If you are not getting it to run for about 5 seconds, you likely have an electrical problem at the Ignition module/CDI nothing out sufficient spark. This would likely be cost prohibitive to repair.
I'm betting on the muffler...
