for the problem 1 , frist u need to change a new glow plug . and make sure the air way of the carb is normal , sometimes the carb will have leak of air (may be the O ring of all the needle are old) and also the exhaust pipe,.... this kind of problem may be cause by several factors......eg. engin condiction, glow plug , fuel tube , leak of air. overheat ,and also the engin setting, and u may need to know the exact temp , .something the thermomter are not accurate.
for the both problem i think it is the temp problem ,may be the thermomter are not accurate. |
