What are you going to use for spark plugs? I think im going with the automotive conversion as my harness ends are Witworth threads. any thoughts?

mine is a mark X. think it woud fit?i emailed the seller to see if he will ship it.there are a lot of mark 9 parts on my engine.the engine mount, ignition ring all said it. is there any way to research were my engine came from? I think it was from a wreck/ground flip over by the damage.any were I can search the stamping as to what it was on?or maybe get a accident report.

hey Wildside , nice to see your back at it . im building mine in my gas station/ auto repair shop. were do you find your wooden propellers? there is nothing around here in the USA. I thought i would get a old airboat prop and cut it down but the Hub is really big. Im was going with airboat because its a pusher prop and the engine spins oposite of our stuff. I did find a really nice overhauled 3 blade for a alvis but the splines were just a little to big. another mistake to hang on the wall

update

Worked a bit on these last 2 weeks. I was able to save 2 cylinders. A little tig welding on the pushrod tube loops. worked out nice. I got all the pushrods in . rockers are not bolted down yet. thats next and i have to bead blast the intake tubes. heres a current picture. I running out of usable parts fast. parts are on the way slowly. Robert

this happens here daily in the usa. my parents have a summer house that was cleaned out off all the copper plumbing and heating pipes. they took all the oil out of nthe tanks and drained out the dirt bike tanks of the gas but left the bikes??!!! there is a local historical park by me that they stole all the brass placards. They caught the guys that did my folks house when they ransacked a church for the plumbing. Ive had stuff swipped from my shop aswell.

updates.

I had some time on the weekend and yesterday. got the rest torn down. everything looked great. I cleaned up the case and degreased it. here are some pictures. now im cleaning up all the small parts.
