The Mower Bench

Thanks Barry. 2 more questions, if I may? Where would I find the solenoid in question and do you have a ballpark figure of cost for a replacement please?

Remove battery under the seat and the battery tray. The Solenoid is on the end of the red live wire bolted on the inside of the body.

 

Hope this helps.

Went to double check that the solenoid was clicking yesterday and got nothing. I pulled the battery to charge it as I found it was flat and left it on charge all last night. It hadn't fully charged this morning (charger light was amber rather than red or green) but I hooked it up as it should have had enough charge for a couple of tries. When I turned the key I got nothing, not even solenoid clicking.

Battery could have completely failed.Can you substitute a known good battery to eliminate that possibility?

Will give it a try when I'm back in on Tuesday. Must admit, I wasn't looking at battery as the culprit as it failed suddenly rather than over time. I found a buggered connecting block at first and repaired that but no success in solving the problem.

Elimination is probably only way to go from now.For info batteries can fail suddenly especially over 3-4 years old.

I'll pop one on from one of the other ride-ons. No idea of the battery's age. Thanks for the pointers.

Being a 4-stroke, this seemed like the most appropriate thread.

 

My Honda UMK435E brushcutter started playing up yesterday. It was running fine, but after about 20mins it wouldn't run at full throttle. It would still start and idle fine, but when revved up would not get to full revs and would then stutter and die, but would re-start immediately and idle well, only to repeat the same problem.

 

Field diagnostics says that taking the air filter off didn't make any difference, so it isn't blocked there, and it isn't running too rich. It doesn't over-rev either, suggesting it isn't running lean either.

 

Job was completed with the back-up Efco, which is basic, has no harness and bad anti-vibe. Hence I don't bend today and rather than carrying on will be having a leisurely dismantle of the Honda to see what I can find. I'll have a look at plug colour, but beyond this, any thoughts/pointers as to what might be up with it?

 

Cheers

Starter for 10.Valve adjustments.

Carbon buildup in exhaust port?

[agg221]

Valve adjustment or carbon build-up - would you expect either of these to come on suddenly?

 

My experience with valve adjustment relates only to car engines, where it's more of a gradual sense of it not being right, which gets much better when you adjust them. My experience with de-coking exhaust valves is sticking a big, flat-bladed screwdriver in the coils of the spring and twisting it round so that the spring snaps shut to knock the coke off the valve seat, as advised in the manual of the Lister B stationary engine in question. I suspect therefore that my experience is of limited relevance....

 

Any thoughts on how to diagnose either of the above, and appropriately correct them for this engine?

 

Cheers
