T20 Tiger Cub Engine Rebuild

hi,
As long as you've got your balls and springs in the pump, I think you're okay there.
It's possible these come with a new pump/a maintenance part?
It's been awhile since I worked on my CUB well nearly 50 years.

Hi,
It's always a pain if you come to assemble something and when you finish there are bits left over.
I'm talking from memory.
I'm not sure and I can't remember where the balls and springs go exactly is there space under the screw ends of the pump for this? If not then they almost certainly go in the current case body.
The reason for me saying this is that this picture shows what looks like Ball bearing valve seat?
Anybody who's recently worked on one of these would probably have a better knowledge than I do not that on my memory is failing it's just said it's been a long time, since I saw the inside of 1.

 

Hi,
Don't attempt to run it until you sorted this problem out of course.
Did you disassemble the oil pump?
Like I said above if there is no room in the oil pump itself for two balls and two springs then these almost certainly will go into the crank case half!
Hopefully someone else will chime in.

 

Hi,
I didn't read necessarily every bit of the articles I've posted above.
But whatever you've done, you're gonna have to strip it down or strip the side panel off again right hand engine case.
And correct whatever it needs to be done you don't wanna put it together Incorrectly.
I know the head gasket was originally copper.
And the base gasket will just be a paper affair?
But it's only a single cylinder with a push road so it's not a lot of work involved in taking it apart again to clean out the sludge trap.
Good luck with your efforts.

 

@Mr.JAJA Here's wishing you lots of luck and hopefully all will be well soon. Good luck Brother.
