I have a situation where my 812 starts up and runs well for 5 mins. After that it starts to spit and won't keep a full throttle. After it cools down it starts up and runs in the same manner.

Now, I know I have a weak electrical connection on the front body panel housing that may get disturbed when I turn on the steering column but I’ve been working with that for a while and the engine has been running fine. Any ideas on why the engine sputters after a few mins. of operating?

Thanks,
Jed

I've had engines that did that due to a marginal coil. Basically, once the coil got hot, it started intermittently shorting inside.

I dunno what kind of ignition is on your 812, but if there's a coil, and it's possible to get at it and run some checks on it, it might be worthwhile.

Check the coil when it starts acting up. If it is real hot try replacing it. Just put your hand close to the coil it can be hot enough to burn you. Also your problem could be the condenser.

Thanks for the lead. I'll check the coil and I friend told me it could cutting out due to overheating. There is some old grass crowded around the cylinder head that I'll unpack and see how it runs.

Thanks for your input,
