I was removing a broken bolt from my 38 a's muffler housing when i suddenly dropped a bolt into the exhaust pipe. I removed the pipe and did not find the bolt in the pipe or the manifold...so i assume it is in the head. I don't want to remove the head or the manififold if i don't have to. it is a small 1/2 inch long bolt so it is not very big. i thought a shop-vac would work or something like that. I did run the engine for a bit and it did not come out and it did not seem to hurt it any but i don't want to risk it. thanks for the help

I had a big piece of the manifold gasket fell in one of the exhaust holes. So what I did was take the spark plug out and stick a air hose with a regular nozzle in its place. Then hold the shop vac. over the hole and try to blow it out. I don't know if it will work with a bolt, but it won't hurt to try it.

I bought a 4 prong claw to get into the head with, also have some magnets i'm going to try. It isn't in the cylinder itself, its behind the valves in the head....it is big enough it won't get into the the engine itself to mess with the pistons but it might stick a valve there is a remote chance at that. on the a there is a valley in the middle of the head that i think it is sitting in so ill try and get the thing out tonight I'll see what i can come up with with(hopefully a bolt)...thanks for the help.

Don't feel bad. I removed the carburator from my D for cleaning and overhaul, plugging the intake manifold with a wad of toweling to keep dirt and rodents out. Took the starter off for checking and cleaning and unfortunately finished that first. Needless to say I had to try the starter as soon as I got it back on. A peice of discarded vacuum cleaner hose, a maglite, mechanics mirror and a piece of stout cord tied to the hose for "steering" along with a final application of the shop vac took it out. Is the bolt small enough to come out the spark plug bore??? If there is a chance get yourself a mechanics retriever (sp) (3 - 4 "fingered" spring loaded tool) fasten some stout cord to the end for "steering" the tool and have a go at it. If you carefully turn the engine over you can be sure the bolt is at the bottom of the cylinder up against the head. An alternative is a small magnet that can be manipulated inside of a flexible tube. Possibly some cheap 1/2" garden hose. Using cord to "steer" the 1/2" hose locate the bolt and then advance the magnet to near the end of the hose. Success is usually achieved with a combination of patience, bullheadedness and some careful thought to avoid adding a second mistake to the first. Vacation tomorrow. No response for 3 weeks.

Hopefully someone will come up with some better ideas. If not and the bolt has a chance of being dragged out of the spark plug hole and you can wait until after April 18 I think I can help you out. I had a chunk of 1/2" tubing which is just a hair too big. I think I know where I can find some smaller tubing and a cylindrical magnet and am willing to give you some help. On the other hand when my manifold bolts were about rusted off on the AR, the mechanic said it was less work to take the head off than the gas tank and we were then in a position to grind the valves which in final analysis resulted in a very nice running tractor. Let me know what happens by email in any case. Thanks! Gotta go.

As I was signing off happened to think of Aluminum tubing rather than plastic tubing. The magnet won't stick to that. Do not extend the magnet past the end of the tubing, and do not drop the magnet. That counts as a second mistake.

Your lucky you did not ruin your engine, find that bolt before you start it again!!!!! !!!! Even if you have to remove the head.
