Wont exceed 4,500 rpm then stalls and wont restart - on route to MOT
totty:
This is kind of on hold as I've discovered the front brake needs servicing (other thread).
I've dropped the needle clips to the centre notch but haven't had an opportunity to test it out. (needles were moved before checking cam timing as I could only find 2 elastic bands and needed 4 to hold the rockers)
Yoshi823:
As far as refitting the cam cover is concerned, just back off all the tappet adjusters completely, and this will give you sufficient clearance. Get it wrong & you could end up bending a valve...i've seen it done.
I had a thought over the weekend about the situation that you have on your engine. Does the automatic advance & retard mechanism work? You may well need to remove the points in order to get a firm enough grip on the points cam. If the cam was seized in the fully advanced position, it would make it difficult to start & to not rev properly. If it is seized, make a mark on both the cam & the A/R units back plate, as it's easy to get the cam 180 degrees out. Check the springs have sufficient strength in them to return the weights back to the rest position...if they've been stuck in the advanced position, it may well have stretched the springs.

I've removed the advance/retard unit as part of the fitting of a Boyer ignition kit.

I'll bet you'll be glad when you get it fixed.
When it stops is it really roasting hot or more normal range? as dropping the neadles will make it hotter ordinarily.
totty:
temp seems normal to me, but i've only got a monkey bike to compare it to. I'm never sure of the needle terminology, I've lowered the clip to the mid notch thereby raising it one notch making it richer.
I can't wait to get it sorted!
