The Apache sat in my garage all spring,summer & into fall. Couldn't get the Keihin carb to pump gas. So, I hooked up an external Mikuni fuel pump,just a few weeks ago. All I did,was hook the pulse line from engine to the pump,run some fuel lines & pull recoil. It started & it runs good. I made NO changes to the carb. It usually starts on 1st or 2nd pull;my best starting/running sled. BUT wait,I have to sell some sleds,thin the herd,so to speak.This is on the list. It is SOLD & is going to Ontario,Canada. Hate to see it go,BUT I have more running sleds.
