I've been super hung up on this mild build's starting issues. I got ahold of the treats 44 mm puch- Hobbit head with the slotted stud holes which I enlarged for the m7 studs I have in their. Currently the mallosi m7 97 mm which works for a stock or this Puch head. The bike occasionally started with the treats head. Fat blue spark. Hpi mini with 300 g wt. Stock shocko. Worked for years before the pull start and head. Put back the original head which is an old motzig squished oem head and presto fires right up runs great but then not and changed to another spark plugs and and fires right up.

Not sure if this is some kind of heat fouling of multiple plugs or is there some aspect of this treats head that makes it even harder to start. I didn't measure the relative volumes of each combustion chamber. I should though.

Has everyone with this head had smooth sailing?? I enclosed some pics of putting a sharpie ink on the head and lightly sanding on plate glass to demonstrate it doesn't seem warped. A leak down is such a pain to.perform.

And yes I also have Graham's newest head but that requires 126 mm studs and.before I do that I still am trying to understand what's up with this. Im trying to be done with the build to move onto a water cooler but I don't want a garage full of non runners.
