NEW OLD 1991 TRX250X

Does anyone have a redcat 250 or falcon 250cc that they can share where the two vacuum lines on the carburetor that you run antifreeze through I honestly have no idea where the lines are suppose to go to circulate the antifreeze. 
 
Any help is greatly appreciated. 
 

Looking for help on wiring up stock wiring harness specifically for a '88 Honda TRX 300 
If anyone could drop a link or send me a PM it would be much appreciated 

Recently I noticed gas leaking from under the gas tank on my 2005 250 2x4. As I looked closer it appears to be leaking from the shut off valve under the tank. It's the valve with the handle that can be turned to open, close or reserve. Can this part be replaced? Thank you.

I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE.
when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out 
 
Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes)
When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
If my bottom end is blow why would it still turn over fine,
Are my valves siezed or not working properly 
or is my timing off causeing valves to not open in correct order with fire 
PLEASE HELP all help is appreciated
