Hey guys,
I just did a cigarette smoke test on my RB30 Patrol today.
Here I attached the photos of the results.
I disconnected the LPG primer vacuum hose from the LPG converter.
Then, I smoked a cigarette and blew the smoke into the LPG primer vacuum hose open end.
Engine was cold and not running
Smoke came out of the air cleaner inlet, top of the LPG mixer & LPG hose joint and then a
temperature sensor(I think) attached to the vacuum line and radiator-cylinder head hose joint(the coolant system)
I would appreciate a bit of help with how to interpret the results.
Thanks
The reason for this test is that the engine is still not running ok. It's hesitating and miss firing more than half of the time.
I'm hoping to rule out any vacuum leak/vacuum advance issues before I move onto other areas to find the issue
