Thermostat

[djape1977]

hi guys. i'm having problems with coolant temp. in my 131. just won't go up. i figured that thermostat got stuck in the open position.
i can't find a new one in serbia that fits my 131. ones that i did find have 3 big water pipes on it, and one that's on my 131 has a 4.th small 6 or 8mm that connects it to inlet manifold. now the question is: what happens if i simply plug that hole in the inlet manifold?

the answer is not much,,,its just so you get a water heated manifold to heat up the inlet mixture when cold .it will be a bit rough at idle put the choke will compenset and youprbley won't notice the any differance.. the twin carb set ups don't have any. so don't worry

anyone ever saw one like this? it got stuck in the open position. had to change it but i couldn't find it, so i had to fiddle a bit and adapt the hoses to fit a normal one.
