I am desparately looking for idle mixer screws for a 1978 440 motorhome TQ model # 9151S. They are approximately 1.5 inches long with a hollow center the entire length. See attached photos. Thanks
Why are you trying to use the 78' TQ. It's one of the worst ones as there are so many emission ports and one off pieces. These are hard to tune even after a good rebuild. The motor home ones were unique. Glen
Glen, as a retired guy working on a limited budget, I'm simply using the carb that was on the engine I bought. I read that the worst TQ carbs were '81 and up. You're right, obviously, motorhome ones are unique! Frank
Thanks for the info guys. I ended up getting an adapter plate to install my Holley carb back on my engine. I will definitely keep your suggestions in mind if I have problems with the Holley.
