Doug&Deb Posted April 22, 2021 Report Posted April 22, 2021 Both my 52 Coronet and the 49 D24 I used to have had the problem of the carb loosening. I’m wondering if the gasket is somehow shrinking as it gets hot. I use blue loctite. It’s not loosening much just enough to need a quarter turn to tighten. I’m thinking of making a gasket from some high temperature gasket material I have. It’s what I have under the sisson choke. Any thoughts? Quote
plymouthcranbrook Posted April 22, 2021 Report Posted April 22, 2021 (edited) Well I never had a problem with the carb nuts becoming loose but did have to retighten the manifold nuts several times after changing the gasket. Eventually they stayed tight. Engines do vibrate and heat up and then of course cool down. Since things tend to expand as they heat up it might be that the heating and cooling cycle is doing it. I began tightening mine up when warm. Maybe that would help. How often do you have to tighten it? Edited April 22, 2021 by plymouthcranbrook 1 Quote
Doug&Deb Posted April 23, 2021 Author Report Posted April 23, 2021 Not often. It was idling a bit roughly the other day and I noticed the carb being loose. The carb is pretty worn. I have another one that I rebuilt. I’m planning on getting that on soon. I’ll try re-tightening when warm and see if it helps. 1 Quote
