• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Hello, just like to say I'm new to the forum, so hello all :-)


I've just come from a cagiva mito to my husky 610

Everyone loves pictures!

Anyway, down to the point. My dad decided he wanted one aswell, so to cut a long story short we went and picked up a 2000 W reg left side kicker yesterday. The thing is, it's a non starter.
I've checked fuel is getting through (had the carb of and cleaned checked everything) and it is.
It's got an aftermarket keihkin carb on it. It looks like a fairly complicated carb compared the original dellorto lol
Another thing I've checked it spark. It's a nice bright blue spark, no problems there then.
So next is compression, and it's got shit loads of that. I've got a compression tester, but I'm not sure what it's meant to read anyway??
I'm not sure what else to check now though guys?
The history I was told by the last owner was that he got it MOT'ed and afterwards when he picked it up it wouldn't start.
So what else can I check? Thanks in advance for any help.

give it some fuel down the carb to see if there is any sign of it firing, if so clean the carb. and try again. is choke working fine, does plug look wet smell of fuel. if its dry then prob carb issue however check valve clearances and valve timing next as if the inlets ant opening no fuel will enter cylinder!
then check the woodfruff key isnt sheared on the flywheel, this would give a spark but at the wrong timing.

check someone hasnt stuck a potato in the exhaust first!!

Hello, thanks for replying. It's defiantly not a fuel/ spark issue as we've just have it started by towing it round the field on the quad :-)
Sounds ruff as fack though, and once it was warned up, was piss easy to kick over... So now I've got a compression issue :-/
Me and my dad have had the rocker covers off and checked clearances, alls good on the inlet side, but alot of play on the exhaust inlet. He thinks they aren't seating properly.
We've also done a leak test (compessing air into spark plug hole) to confirm a dodgey seating of the exhaust valves :-/

So tomorrow things to do are;
Take off head and check valves are seating

What other things could cause lack off compression? We done think its rings as there wasn't any leakige of air into the bottom end...

All in all, a very progressive day (waiting around all day for a flywheel puller) lol
 
what sorta noise does it sound like, if its top end clatter it sounds a bit like too wide valve clearances.(REMEMBER ITS GEAR DRIVEN CAMS SO THEY ALL SOUND A BIT CLATTERY compared to full chain system) when warmed the decompressor actually is close enough to act,make sure when checking for compression with the compressed air that the decompressor isnt opening the exhaust valve, remember this when checking valve clearances as well. (your first thread said u had loads of compression? dont know exact figure but anything over 100psi? 120?) if it didnt smoke loads when running it sounds like rings are not the issue. if/ when the head is off, turn it upside down with the spark plug in and all valves closed, fill combustion chamber with carb cleaner or wd 40 and see if ports start to seem wet. this will show a poorly seated valve. when you take them out you will see if its anything major with valve faces or seats.

check valve lengths, spring height and cam lobes, if all ok then lap the vlaves back in and retry the above test. keep lapping till the ports stay dry. if your having the pot off then check big end and mains for play, perform usual bore ovality checks, piston to bore clearance and ring end gap. replace as necessary.
