So did you just double up on the base gasketS? what did you do about the squish ? The shop that sold me the kit said it’s ready to run out the box regarding squish ect ect it’s not a problem if not tho how did you get round it?

I have lots of base gaskets kicking around. So used two from another kit.
With the transfer ports flush it was a fraction over 1mm squish, which worked ok. I tried running it as it came, but it wasn't as good.

Got some satin black on the grab Rail and side case. the kick start I used Ford midnight sky, old Sierra sapphire Cosworth colour I think

I want to stick with the original air box mainly as I don’t want it to loud so hope this filter may be a bit more free flowing

[yambw’s]

Can’t do much to the engine at the mo so started messing with panels a little today, test fitting ect..

[yambw’s]

Few added bits and bobs to aid the engine rebuild

[yambw’s]

So I had a few hours free today.. bearings and crank are in and cases together I copied 90gtvert’s technique except I used a heat gun rather that the oven, worked a treat also went with 1184 in the end as seen in one of his YouTube video I liked the way it stuck to the cases all be it a little runny crank just needed a little tweak with the crank puller at the end

So I’m test fitting the cylinder atm could do with some advice please. Two scenarios 2 base gaskets =Level port with piston crown and less squish




Or one base gasket =ports a fraction Bellow piston crown and more squish unable to measure squish atm this is all eyeballed at the mo what do you guys think ?

[yambw’s]

I guess what I’m saying is what’s the lesser of two Evils ? I realise once torqued down it will pull the barrel down more

[yambw’s]

If I were to use two base gaskets does it matter what order they go? I have 1 card 1
metal gasket

It looks like two BG will be perfect after torqueing the cylinder down. You can put spacers on the studs, then the head bolts and sung them down a bit to get a better look. I would not fully torque the nuts down without the head. I broke the cylinder one time doing that.

It does not really matter, use a small amount of sealant between them.

[yambw’s]

Ok thank you oldgeek. So keep the mating surface of the two gaskets dry? and just a little to stick the two together correct?
