Reply To: Head gaskets and crank seals

[need2fish]

Comments not related to gaskets, but to hard starting: I have a K-70 and a K-50. Both were suffering from hard starting, especially when cold. Carb/Ignition were not the problem. In an effort to track down the entire “food chain” of combustion I found the relatively small exhaust opening in the bottom of the head/cylinder block and the portion of the leg where the exhaust makes a 90degree turn were completedly carboned up. Reaming both portions of the exhaust path improved both starting and acceleration.
