Not firing on 1 and 2
The motor runs and I have confirmed spark on cylinders one and two but it's not firing. I have checked and rechecked everything yet it won't fire
on one and two. I'm afraid it's the head.
Any suggestions, especially those that don't include a stuffed head, are greatly appreciated.
Thanks.
Ross.

I've checked and rechecked firing order and plugs. Good spark at the plugs when they're pulled out and earthed. I should mention, it's a 1200 so
of course single port and single carb so I've ruled out fuel because it's running on cylinders 3 and 4.
I'ts got good almost new leads (proper VW ones) too.
Any other suggestions????

Well, after all the heartache thinking the head was stuffed, I sprung for a compression tester and the result was excellent. Running 150psi, more
than enough.
The only other thing I can think of is a leaky inlet manifold leading to such a lean mixture that it won't run. Does this sound right???

I'VE GOT IT!!!!!!!!!!!!
By chance, I found a hole in the intake manifold on the right side. It was hidden down on the bottom (on the fan side of course) where the heat riser
pipes meet the manifold. Who knows why it got a hole there (it was about 5mm across), but I've fitted another manifold and all is well.
Thanks guys.
