ssdt1980 Posted November 2, 2021 Report Share Posted November 2, 2021 Hi Due to a number of reasons I'd not run the Rev4 for over a year... After getting it started at the trial it ran OK up to a point it intermittently cut out queueing at some sections and was pinking a fair bit. Any advice on what might be causing this and what to do? Old fuel probably didn't help... 😣 Quote Link to comment Share on other sites More sharing options...
b40rt Posted November 3, 2021 Report Share Posted November 3, 2021 (edited) Have you stripped and cleaned the carb ? Changed any old fuel and filters ? Edited November 3, 2021 by b40rt Quote Link to comment Share on other sites More sharing options...

There wasn't a lot of fuel in it, so topped it up with fresh, changed oil and all filters, new iridium plug... Haven't had the carb off not sure how easy this is....

carl ekblom Posted November 3, 2021 Report Share Posted November 3, 2021 I think you have a fuel delivery problem.... somewhere..... perhaps inside carb, but always good to replace the spark plug after long standstill. Use plug accordingly to manual. Nothing else. Quote Link to comment Share on other sites More sharing options...
