Does it swivel in the middle? How does it steer?

briggsbits might be able to help. But your engine maybe too old for them.

Nice find, Is it a runner?

Leave it as it is ,it's only original once

Try a PM to Rolloman he maybe able to help

If head is warped you have nothing to lose by following what Anglo Traction suggests to sort warped head.It will be cheaper and more satisfying if you can sort it yourself rather than using a machine shop.

Looks like head gasket has been leaking, I have found in the past that some kohler heads seem prone to warping. A quick check of head for warp is to place a straight edge across head face and look for light under straight edge. more accurate way is to try and slide a feeler gauge between bottom of straight edge and head face.check diagonally.

Is that Douglas arrived ? Kermit will be feeling left out!

Very nice patina .definitely one not to paint

Looking good, a job well done

Good to hear you got a result.

Any luck getting your engine started?

Is the choke working properly?

You might be able to find a parts list on the briggs website,armed with the part number for the coil, search ebay for a replacement.Alternatively you would be able to get a genuine replacement from briggsbits they are UK based

Nice find!
