Default lister d 2hp starting and running problem

hi

i am having a problem with my 2 hp lister d, i have rebulid it up and cant get it to running for more then a couple of minutes

i have put all new gaskets on, head gasket on and new piston rings, as compresson was abit poor and water was leaking into the cylander when i first got it

i have cheched the mag and cant find a problem with it and set the valves at 31tho and made sure the timing is correct at 20degress before tdc

was wondering if any1 else has had this problem before and may know the problem

I'd guess it could be...

insufficient fuel... run it with the float chamber lid off and see if the float still stays floated.... unless you have nice paintwork as fuel might slop everywhere. Edit: ensure you don't set light to your shed whilst doing that.

The mag could be playing up after a short while or it could be the plug playing up as it warms up.

I would swap the plug or investigate that first.

31 thou is a huge valve gap !
I know it states that gap in some books but 12-15 thou is much better.
All my Lister D's including my daughters 2hp are set at 12 thou.

Is there still compression when it stops?

My D had a worn valveguide so a soon as it warmed up the exhaust valve would get stuck and stay open.

Regards Brian

Is it running too lean on the mixture? When you start it does it black smoke, if so then just screw the mixture wheel in until it just stops smoking and that should be correct. One of my D's would start easily without any smoke but would cut out after several minuites, I had to rotate the mixture control another turn anticlockwise and it now runs fine.

Pete.

hi brian theres no problem with compression as it will start back up stright after it has stopped and run again for a few minutes

but dont know if theres such a thing as too much compresson for lister ds as is bit hard to turn the starting handle when it bulids up compression
