Hello all, I was recently given a Petter A1 petrol engine to restore,I used to have a restored LD1 but had to give it away to make space,i'll get another one one day...Anyway I know A1's aren't all that great but it's still interestingworking on it! It's got a good spark now I cleaned up the mag and thecarb is repaired but when I turn it over with my hand over the exhaustI feel it blow AND suck through it, this indicates the valves are notsealing properly and this is backed up by a very low compressionfigure from a compression tester. I want to grind the valves in andclean out the carbon buildup that is almost certainly in there,however, does anyone have a number for a company that can supply methe gaskets i'll need? I will need a head gasket and presumably onefor under the cylinder where it meets the block, or isn't there onethere? I have made my own carb gaskets using gasket paper but can youget material to make head gaskets?Here are some pics and text I have put together and will update as Ido other jobs for any info!James

Hi,

I have just acquired two Petter A1s. One was complete and after servicing the magneto is now running so I will now start to renovate. The second one doesn't have a magneto but I am little confused. The one that is now runn ing has a Wico magneto that fits directly into the back of the timing chain housing. The engine with the missing magneto has what looks like a cast a luminium housing fitted to the back of the housing - does this mean that I need a different type of magneto?

Hoping for some advice.

Andy
