Just purchased a 90 with 10 valve engine

[rick hayllar]

Thanks for  the encouragement all.
I got the beast home on a trailer today and started it up, and disconnected 
a taped together broken connector ( the idle microswitch cable I believe and 
now I get plenty of revs. So it looks like the idle switch is at fault.
Regards
Rick
