Extended engine crank time unless started daily.  By  quail (Read 626 times)

My mc 54 250b has had an extended engine crank time since it was new. You have to crank it 45- 60 seconds before any fuel gets to the carb. Then it will fire stumble and fart for 10 seconds, then it will idle if you hold the throttle a little open for 30 seconds, then it idles and runs fine.

That is unless you start it daily. Then it cranks in 2 seconds and will idle, take off and ride if you want to. I replaced all the fuel lines, fuel pump (2x) and fuel filter. Has anyone seen this problem. I am afraid I will kill the cheap starter.
