Hi LEE pm me if this does not work out thanks Jon

If it is difficult to start it 'may' have dropped a valve.

Or a liner.

I run the old girl for a few hours work couple times a month.

 

Noticed she was abnormally difficult to start this time

weird i thought, (good battery, and alternator fitted last year)

 

Once running Noted the engine was laboring as i revered out of shed as i normally do in tick over and she chonked out. (as though i had the braked engaged)

 

Drove it about a bit, and was struggling in lower rev's, much smokier then before.

Also laboring when stationary and running pto splitter, also stalled a few times.

 

Give it a good run about, but no improvement.

 

Condensation build up in fuel tank?

 

Hi mate just to mate it return pipe from the pump lee thanks Jon

On our lister when rebuilt; one of the pots (air cooled) was sucking and blowing. so we retorqued it and it sealed. Im just wondering of your head gasket is gone, or if your head could have warped?

 

This man was bang on - head gasket gone. Air, fuel filters were all good.

Cleaned out primer bowl etc, and checked the injectors. Still had issues, mechanic is changing gasket tomorrow. Will update in a bit.

While the head is off check the liners are not below the block surface. If they are then blowing gaskets will be the result.

Ill pass that on Cornish. Good tip, thanks.

Got the 35 back on Friday. The blown head gasket was the only problem. She is back on top form, full power, starting on the button etc. Glad it wasn't anything worse.

Thanks again for every bodies input on this earlier.
