Possible ignition. Are the cap,rotor,wires,and spark plugs all good? These are the common reasons.

AnswerEither is possible. If it's a regular miss caused by a plug, wire or distributor cap, one of the spark plugs will be fouled or wet at a minimum. Check that first.

It's always possible that there is a problem with one of the valves, so you might want to run a compression check. If one cylinder has far lower compression than the others, it's probably a valve.

If it's an irregular miss it could still be the distributor, but it's more likely a carb problem if you've eliminated all of the other problems.

It is largely dependant on the carburetor, intake manifold, exhaust system, and ignition systems used, as well as how you route the air in to the carburetor. The best bet is to test on a dynomometer. I would guess in the neighborhood of 230 hp. with stock intake and ignition parts...

Schematic of carburetor of 1985 Chrysler fifth avenue?

If your car is running poorly it is more likely the "lean burn system" located in the air cleaner. This is an over done electric ignition that after 20 years is probably shot. NAPA sells the replacement module for $135.00. A MOPAR electric ignition conversion kit #P3690426 is about $200.00 and will fix your problem for good. Don't go into the carb until you try the ignition. I did and it was the ignition system which I replaced and it runs great with the kit.

Why does a Briggs and Stratton 4.5 HP lawn mower engine surge?

Surging is the result of a "lean" fuel mixture, meaning too much air and not enough fuel. The problem is most likely a dirty carburetor or an air leak in the intake system. To fix, inspect the carburetor and intake manifold for cracks or looseness. Tighten all fasteners to ensure all seams are airtight. Clean out the carburetor with some carb spray and blow out all holes/orifices with compressed air. If problem persists, carburetor must be removed and disassembled/rebuilt.
