6hp woes

After numerous starting problems and after repaceing the impeller, I finally took the 6hp engine to a pro. He found a busted head gasket and warped head which he had milled down. After replacing the whole mess, he did get it running again. When I got it home I put in the run barrel and pulled the rope. It just hung there. I wound it in by hand and tried it again. It pulled and retracted normally two times and then on the third just hung again. I noticed a chip on the pinion gear ($50 part) almost to the teeth. I took it back.

The mechanic showed me how it had to be in neutral to start and that the pinion was not stopping the engine from starting. He jiggled the shift lever and pulled it through. It wouldn't start. After a few minutes of messing around it finally did start. We let it run for a while.

When I got it home I put it back into the barrel and tried to start it. No go.

All I want is an engine that will start when I want it too on the first or second pull. What else can I replace? It already cost me over $200. I'm to the point now where I don't care if I have to spend a few more bucks. I know parts are hard to find. The engine does mean something to me so getting rid of it is not an option. Any ideas would be appreciated.

Next time you try to start spray a oil gas mix in carb. if it starts you know its a fuel delivery problem. I am assuming its a 2 stroke

Yes it is a two stroke. If it is a fuel delivery problem, it might be where the line connects at the tank. That connector is hard as heck to get the thing to clasp.

First, is it Chrysler? Second, What year?

Third, If it is a Chrysler, the pinion is only 12 bucks and takes 10 minutes to replace. So even at 100 bucks an hour which is the going rate around here, 50 bucks is a little high.

Sounds like your recoil spring is not wound tightly enough to reliably retract the pull cord.

Starting reliably is always a problem with these small engines if anything is wrong. So in addition to the fuel supply, you need to check the setting and condition of the points. At this point, if you do the work yourself, most likely you will not need to invest too much more money. Even if you are mechanically challenged (politically correct) 20-30 bucks for a Clymers manual would be an excellent investment. These engines are really easy to work on.

if the clasp doesnt hook good that could be your problem it could be sucking air.and yes you should be able to fix yourself like stated above

I took off the part on the gas tank that the fuel line hooks up to. It may have been sucking air in through there. I put some Teflon on the threads so maybe that will help. I'll try it tomorrow.
