wolp Posted August 4, 2021 Share Posted August 4, 2021 I have a problem with my Brumby. I've had 5 competent mechanics look at the engine and none have been able to resolve the issue. During summer, if the engine is started from cold the engine will drive for minutes or hours without issues. However, when the engine has reached it's operating temperature and then the engine is turned off and then back on again, say minutes later (as one does when filling petrol etc. ) the engine will start to buck, that is it loses power and restores power every 5-10 seconds. Fuel lines have been checked, fuel filters changed all to no avail, which makes sense as the car drives normally from cold. Has anyone experienced such a problem or knows what the problem may be?

Sounds more like an electrical problem to me. Wires or connections are expanding when warm and losing connection or ground. May need to jiggle wiring harnesses when cold to see if problem re-occurs.

wolp Posted August 11, 2021 Author Share Posted August 11, 2021 Hello Dee2, I don't know why but i didn't get a notification that you left a message. I agree with you. it does sound like an electrical problem. It's so tight under the hood that i don't know where to start yet. I've got myself a service manual and will be familiarising myself soon and hopefully get to the problem. Thanks. John Quote Link to comment Share on other sites More sharing options...
Dee2 Posted August 11, 2021 Share Posted August 11, 2021 May want to take a look into the distributor to see if anything is faulty, loose etc. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted August 12, 2021 Share Posted August 12, 2021 To keep things together, this is the previous discussion posted in the 90’s model section (because it’s a late model brumby). Cheers Bennie Quote Link to comment Share on other sites More sharing options...
