I would like to make you some questions as follow:<br />1- How to check my charging system: Even that Tachometer is working, the charging system does not becaused I measured directly with voltmeter in battery terminals while engine running in 1500rpm and still in 12 volts! <br />I presume one of both rectifiers are not working!<br />How can I check both rectifiers?<br /><br />2- When start engine at cold condition(every morning), engine generate to much smoke. In fact, engine hesitate to start and after 2 minutes smoke decrease and engine is working fine.<br />I presume that Oil injection system deliver to much oil at idle speed. How can I adjust the Oil injection system? Or better eliminate it? and use premix oil?<br /><br />Thanks for your attention.<br /><br />Regards<br /><br />Carlos Schemel<br />Venezuela
