1941 buick special
ever since I had electrical work done to my buick to get the lights, etc. working the starter sounds like its kicking on as I accelerate and hitting on the flywheel.The work was done by a very reputable shop that work on nothing but classic and antique cars. He thinks it is a vacuum lockout problem to keep the starter from being engaged once the engine is running. Where is the thing located, and is this the problem? Is this in your scope of knowledge, 41 buicks?
No I do not know 41 Buicks. Did you take it back to them? Since they are antique auto experts I think they are your best bet.
car gurus? isn't there anyone there you can turn to?
I doubt you will find anyone better than you already have. Try an old Buick forum or club.
CG's is volunteers like yourself who answer questions. We don't get many questions about 78 year old Buicks.
One last thing. Try using a multi-meter to trace out the circuit. It should be pretty easy.
Assuming your starter system is stock the problem could be with the start switch under the carb. Buicks used a system for may years...turn on the key and push the accelerator to the floor...the linkage to the carb was attached to the start switch. The system worked on vacuum ...if the car was not running there was a ball in the switch that make contact with the start system...when you pushed to pedal down that activated another switch and power went to the starter....as soon as the car started, engine vacuum pulled the ball away from the contacts and the circuit was open. Something is wrong in your system and when you accelerate, that switch is sending current to the starter and it is trying to start the car that is already running.
here is a page from the 1939 service manual showing the start switch mechanism under the carb
