One cause of rough running that I haven't seen mentioned is a sticking exhaust valve. This is very common on A4s and easy to address by fogging the engine with Marvel Mystery Oil. With the engine running, pour a small amount of MMO into the air intake. Repeat a few times and it will usually free up

Have stayed out of this A4 thread for a variety of reasons, however based on plenty of work over many years with carbureted engines I second Bruce's emphasis on making sure that the fuel supply and carb are verified as a priority, before proceeding to other more complex causes. (steps 1-4) In my

Hi Lee, having had an Atomic 4 for 15 years, I can say the 2nd video sounds largely normal once you got it starte. So, it seems yo tell me compression is OK. The first one sounds a little rough, like a fuel issue. That could happen if the engine was run all the way out of fuel ans you had limite

Lee, I'd suggest you take a look at the carburetor, stuff tends to grow there.  I had a similar situation over a long winter layup and found, believe it or not, spider webs in the carb.  It's not too hard to take out the main jet, spray down with carb cleaner and blow everything out. Neil Ga

We picked our prior boat, a 72 35 MK1, at an auction. The person that brought it to the sale location did not open the seacock and the engine overheated so bad that the paint burned off. I am not too sure what degree of harm it precipitated. But eventually, I got it running like a champ.
