CB750 / Re: 750F2 erratic tick over.

not sure if your model has an automatic advance and retard thingy, but mine (K6) had erratic tickover. i changed carb rubbers jets, air filters but when i checked the advance re-trad ting it was dry and sticking. now after cleaning and a light bit of oil the tickover is brill, just a thought

Well I found the fix
The auto advance was semi seized (I may have sprayed dry chain lube in it) it was stiff as hell but did move so it was all or nothing so when I strobed it the marks were not at all static now as I rev they come it to view as the revs rise

no i did not refit the coils. i did do nearly 200 lovely miles Sunday. it has a small missfire at around 3K like a hesitation but other than that it runs great. i will re check the timing when i have five Min's.  I called in Abergavenny on Sunday and when i described the hesitation at 3k a chap there who said he had a Honda dealership back in the 70-80s said the autoadvance springs were a bit tired. and a fix they used to do back then was to chop off the eye of the spring and fashion a new eye thus shortening the spring by a tiny amount made up for the slack in the counter weight. has any one hared of this?

thanks Guys,lots for me to look at. when i put the cam back in i had the timing mark on the crank and the notch on the cam lined up. is there another way. surely if the notch is pointing up and the two lines are horizontal also 1-4 is at T then the cam is timed? or am I wrong? i can just about see the notch in the cam with the engine in the frame.

just tested the coils they look fine. each one registered 10.3 to 11.4 and the new NGK caps were all at 4.9.

next i am going to strip the carbs and check in case some dirt got in them while they were off the bike. i will also look at the rubber boots while i can.

Thanks Sparrow1
they are the original that have been on the bike for the past 2 years when it ran great. i will still check to see if i damaged any of them putting them back on.
