JJC Posted July 21, 2020 Report Share Posted July 21, 2020 I’m fighting the rear Stromberg. It floods but not until the engine has been running for 5 minutes. The carbs were rebuilt about 4 years ago. It’s not the grose valve, not the floats nor their settings, needle and piston ok. Anyone experienced this? JJC Quote Link to post Share on other sites
stillp Posted July 21, 2020 Report Share Posted July 21, 2020 I didn't have any luck with Grose jets and reverted to the standard brass type. Pete Quote Link to post Share on other sites
JJC Posted July 23, 2020 Author Report Share Posted July 23, 2020 Looks like a leaking (new) Grose valve. Anyone else experienced that? JJC Quote Link to post Share on other sites

JJC They had a bad reputation a few years ago but I thought they had been redesigned to cure the problem so maybe you had an old stock one. Stuart. Quote Link to post Share on other sites

JJC Yes and went back to SU GSU102 needle and seat assy. One Grose jet caused flooding oF the float chamber. That was 15 years ago. Peter W Quote Link to post Share on other sites

JJC Posted July 23, 2020 Author Report Share Posted July 23, 2020 Have ordered the needle version from Burlens. The Grose is going back for a refund to the other supplier JJC Quote Link to post Share on other sites
james christie Posted July 23, 2020 Report Share Posted July 23, 2020 Memories, memories. I remember a certain Peter W stating some 50 years ago, that if we liked cars from the fifties they didn’t have to smell like one and he could provide the solution, Grose jets! I succombed to his excellent sales patter and fitted them to my 3A. They have never leaked james Quote Link to post Share on other sites
