Is nine months long enough?

[PWL216 1,215]

I had a problem with my 520 H  where it wouldn’t start. I had a mobile service come in and they couldn’t get it started, and he recommended a professional shop to bring it to. So I did. They’ve now had it for nine months. I don’t think they’ve spent a lot of time looking at it other than to change the fuel pump and maybe clean the carburetor. At this point, I think it’s a matter of pride to them. But at the same time, I know they’re not working on it. I called and left a message this week and told them I have to pick it up by the in May, fixed or not. I think I’ve been pretty patient.

Ok might be a stupid question but why couldn't we fix it here? We have a couple of 520 experts.

@WHX?? that’s not a stupid question at all and in fact, there’s a good suggestion. Thank you. If it’s not running when I pick it up, I might just bring it to the show.

Get it from the shop

Describe ALL of the issues and circumstances about it as much as you can. 

Let RS help diagnose and give a plan of attack and you follow the instructions. Some guys on here know those Onans well.

Viola, a running machine if it isn't something catastrophic going on

I'd be happy to help diagnose it along with several others.

Thx @wallfish I’m confident it’s nothing catastrophic.

I wish you were closer.  I'd have you bring it over.  It would be fun to troubleshoot it.

Spark, fuel, compression, and a way to crank it over.

 

I have used another tractor to crank an engine to check for spark.  Just park them PTO to PTO and twist the belt. 

A thumb over a spark plug hole while cranking will indicate compression.

Spray fuel directly in the carb while cranking.

Like @wallfish said, tell us what it wasn't doing before the shop on wheels got there and what is and isn't doing now. We will go from there.

520. If it cranks  check for fuel and spark. Easiest way is to spray a pit of carb cleaner into the air intake of the carb. If it pops, you have spark. If it doesn't most likely ignition module or coil. If it doesn't crank, first place I would look is nototorious 9 pin connector.

Some so-called small engine shops have no idea about how to diagnose and repair an Onan engine. If its an electrical issue, a good multimeter, a copy the electrical Demystification Guide, and a little common sense is all you need. If it's fuel, that's just plumbing.

So true unless they have a old timer that's been around the block or a young tech that really studies his trade. A good shop will be up front and tell you they know nothing about Onans instead of just taking your money for nothing.

Somehow many think that an Onan is different.  If you are having problems just download the service manual, for an Onan download it here.  An operators manual is available here.

Most small engine shops only want to do 2 things. Sell you equipment or service what they sell. That's about it.
