Valve spring problem/question
« on: January 06, 2010, 08:04:23 AM »
I have built the "4 in 1"vacuum engine and it runs real well the onle problem I have is the valve spring, with the flame on it it seems to loose the tension which prevents the valve from sealing properly and the engine slows down. After each run I have to retension the spring. Is there any way of overcoming this problem?
cheers curtis
