1993 Gyro X - worn piston rings
Posted: Mon Aug 24, 2020 3:51 pm
can anyone point me in the right direction for getting the correct parts for a top end rebuild on the TD01 engine stateside? or know of any compatability with other models ?
backstory if iterested:
I was working on getting the carb adjusted (again)
up on the stand, idling great. give it about half throttle-- still running good.
open up the throttle a few more times. eventually sustained wide open for 30-60 seconds and it would stumble in the middle briefly. almost certain i was briefly seizing up the piston.
turn it off, inspecting things and notice that i forgot to reconnect the oil pump cable to the oil pump, after reinstalling the muffler. checked the compression, it's about ~75psi -- which as I understand is pretty low.
I haven't been able to get it started since.
tl;dr: ran it WOT in the stand w/ oil pump cable disconnected, need new piston rings
cheers!
