Hello, I dont know if I have got the hang of the kickstartprocedure of my srx. Because of the automatic decompression unit I actually dont know how/or when to kick. Should I slowly push the kicklever down intill it stop and then let it up and then do the real kickdown fast? Or how is the correct way to do it?

Aye Peter,
Slowly push down on the kickstarter until you feel the piston coming up to TDC on the compression stroke. Then allow the kickstart lever to return to the top of it's arc. Now apply steady pressure to the lever and you should feel the piston just go over the TDC on the compression stroke and release the kick start lever to return to the top of its
travel. Now, kick the lever down, with a long swinging thrust, through the full arc of the lever.
Beware! If you hit the kickstart lever off the 'stop' at the bottom of the arc, you may split the forging at the bottom of the lever and they are not cheap to replace, if you can find one!
IMPORTANT: Make sure that you have adjusted the 'free play' in the automatic decompresser to within the range specified in the workshop manual. If you have too much movement, not only will you not 'feel' the piston going over TDC, but the cam will interfere with the top of the valve and could cause wear/damage to the exhaust valve.
If others have different techniques, please describe them.
I hope this helps. Good health, Bill
Aye Peter,
Tryck långsamt ner på kickstarteren tills du känner att kolven kommer upp till TDC på kompressionsslaget. Låt sedan kickstart-spaken återgå till toppen av bågen. Använd nu ett konstant tryck på spaken och du bör känna att kolven bara går över TDC på kompressionsslaget och släpp kickstartspaken för att återgå till toppen av dess
resa. Sparka nu spaken neråt med ett långt svängande tryck genom hela spaken.
Akta sig! Om du slår kickstart-spaken från "stoppet" längst ned i bågen, kan du dela upp smidan längst ner på spaken och de är inte billiga att byta ut, om du kan hitta en!
VIKTIGT: Se till att du har justerat "free play" i den automatiska dekomprimatorn till inom det område som anges i verkstadshandboken. Om du har för mycket rörelse kommer du inte bara att "känna" kolven som går över TDC, utan kammen kommer att störa ventilens topp och kan orsaka slitage / skador på avgasventilen.
Om andra har olika tekniker, beskriv dem.
Jag hoppas det här hjälper. Bra hälsa, Bill

Thanks for your reply Bill. It felt a bit embarrassing to have to ask the question but I realize now that it is not obvious how to do it right.
-
Aye Peter, no need to feel embarrassed, we all have to learn, life's little foibles. ;)
Remember, about the 'Prime' position of the petrol tap and also priming the cylinder afore switching the ignition 'ON', as I described in my email.
I hope this proves successful.
Good health, Bill
Hej Peter, ingen anledning att känna sig generad, vi måste alla lära oss, livets lilla svårigheter. ;)
Kom ihåg att det är "Prime" -positionen för bensinkranen och även att grunda cylindern innan du slår på tändningen "ON", som jag beskrev i min e-post.
Jag hoppas att detta visar sig vara framgångsrikt.
Bra hälsa, Bill

I think I found my problem. The choke piston was only able to pull out half way. It got stuck in the carburetor for some reason. If you loosened the nut in the carburetor half a turn, it could move all the way. I solved it by putting a thin washer between the nut and the carburetor. Have tried cold start now twice without problems. I measured the gap in the decompression device to about 4mm (3-5mm). I already have a crack at the forged end of the kick arm but it has been there for a couple of years. One fine day I will make an attempt to weld it.
-
Aye Peter,
YES! Pleased to read that you have found the problem and been able to sort it out.
Hopefully, the lurgy will pass in Sweden and allow you to take the SRX or the SR for a nice canter. ;)
My regards, Bill

The trick is to run faster than the virus's spread rate.
Thank again
Peter ;D
-
;D I'm no as quick as I used to be! ;) Regards, Bill

I have made three cold starts now and it has started on the first kick every time.
I am happy. :-)
-
If you are so am I! ;D ;D ;D ;D ;D
Good health, Bill

Had mine twenty plus years, still struggle some days. I find the best way is if it wont start using te standard approach, then surprise it by changing tactic, seems to shock it into starting sometimes :-)
-
He!He! ;D ;D ;D ;D ;D
Like it, Bill

Yes, you can't let the buggers think they have the upper hand...
