Adventurer starting Problem
Hi, I have a 2001 Adventurer which has become a pain to start when cold, this started last year and has got worse during the season, (the last time I flattened the battery and gave up as a winter project) the only way I could get it to start was choke full on for a couple of revolutions, choke off, no throttle and stab the button, it would fire and sometimes tick over long enough to slowly increase choke and throttle to run. Most times it wouldn't tick over and just die. Full choke again and try the again, it would never fire with the choke open, it seemed to flood (sorry never pulled a plug to confirm) so choke and throttle off and it would fire again, so on so on. When it was warm/ hot it would start ok!, never first stab but after a couple of revolutions, when running it was fine, no hesitation, would pull and red line and tick over.
So I have pulled the carbs, Mikiunis? fitted and checked and blown through every orifice, float levels I understand are 14.5mm, pasted a couple of photos showing how I interpret the 14.5mm to the bottom of float, not the ridge around the float?. Please confirm? The air filter/ box are all standard.
I am also checking valve gaps, (pasted below)
1ex is to tight
2ex is to big
3ex is ?
All inlets are tight, but in tolerance, change them??
The bike has had new coils, an Ignitech igniter with Irlmikes mapping,(4 years ago) the problem has only started last year and gradually got worse through the year.
Anything else to check/ adjust/ any thoughts??
