Speedaire compressor with Honda GX390 engine

I have a Speedaire compressor with Honda GX390 engine, it starts and runs good but when the compressor gets up to pressure it slams the choke back and kills the engine. I changed the throttle control cable and took apart and cleaned the pilot valve. Even tried to adust the pilot valve. It still does the same thing. Can anyone help. Thanks.

I think I'd slip the belt off and see if the engine will run at idle. It should kick the throttle to idle, not the choke, and it should unload the compressor, so the engine can idle once the pressure limit is reached. If it has carb problems, it might just be killing the engine instead of idling it. Could also be that the idle speed screw needs to be screwed in some.

Craftsman/Kolher Lawn Tractor Dies

S

Slick on Apr 18, 2006

OK, I'm stumped. I've got a Craftsman 46" lawn tractor (model 917.272121) with an 18.5HP Kohler (CV18S). A couple of weeks ago I go out and start... make that try to start it and nothing. I jump it and get it running, warm it up, depress the clutch/brake, put it in gear, and as soon as I let the clutch/brake up, it dies. The battery still has enough juice to start, so I begin fishing for problems. I check the kill switch under the seat, nothing. I then find the switch interlock push-in (153664) and figure out how it works. A little duct tape later and I've now got it running. Mind you, this is just so that I can isolate the problem. I drive it around and conclude that I'll be buying a new switch interlock push-in. Then it happens. I reach for the attachment clutch switch to engage the blades and it dies on the spot. Argh! The next day I put a new battery in it, and I've got a new switch interlock push-in on the way, but if it's not the switch interlock push-in then I'm going back to the drawing board. :wall: Anyone have any ideas? My choices are buy a bunch of parts and try them one at a time, or buy one, wait a week, test, fail, buy another, wait a week, test... well you get the picture. Thanks, Slick

Riding mower blades won't engage in low cut height

J

JamieO on Aug 25, 2014

I recently got a Bolens (MTD) riding mower as part of the deal when I bought my house. For a couple months, it worked just fine, but for the past few weeks, I can't get the blades to engage on any height setting lower than 3. Prior to this, I mowed on 2 with no issues. It is a 38" cut model with 2 blades. Any ideas on what might be causing this?
