225 popping out the exhaust, but...

The condenser prevents (absorbs) arcing of the points. When the points arc, they act like they are closed, and a closed point is not firing the coil. do that 4-5 times in a row and then get a good one off and itll ignite its cylinder as well as anything left in the manifold.

We had a USMC guard mount gas truck do that, you get off the gas and about 3 seconds later it sounds like an 81mm mortar firing. The truck had about 4 feet of exhaust on it and I bet there was jack left in the muffler. Funny as hell because the duty driver would pop that thing on purpose a minute down the road before he pulled up on your post.
