It was down on power and rpms. Cleaned muffler, air cleaner, changed plug, adjusted throttle. Nothing helped. Constant porblems using it in the July heat, so I gave it the old heave ho. Broke the carb off at the spacer. Took it into dealer for repair, 5 days for parts delivery. So I bought a t-270 to use now. I am impressed with my old t-27. The fuel tank and lines and carb appear to be the only difference between the two. Never had any problems with that model. However, the t-27 has way more power and rpms???probably needs tuning. Paid 350+tax. Is that a good price? Will repair the 230 to use again, as I like it's light weight.
