Cazza Posted January 22, 2012 Share Posted January 22, 2012 Hey all, getting desperate for ideas now- what can you throw at me... My 1600 kent crossflow engine has been playing up for a while now. Has lost alot of pulling power, constant tappet ticking,generally runs rougher than it used to, and when i try to drive at a steady speed below 60kmh it surges (and i mean REALLY bounces) its way along. Carb all seems to be working sweet (apart from the fact the blimmin gates have started tapping) so doesn't seem to be fuel issue, have replaced points/plugs/distrib cap/ignition coil...........i'm running out of ideas. compression tests have returned a steady 180 across the board (couldnt ask for better!), have tried screwing with the tappet adjustment and advancing the timing- not helping. all useful suggestions welcome but please spare me the time-wasting "replace it with a 4age/ 2litre etc." crap okay?

Beaver Posted January 22, 2012 Share Posted January 22, 2012 when you say screwing with the tappets, have you actually set them to what they should be? personally i would set the tappets, timing and points etc all to factory and then start hunting for a cause. oh and have you replaced the condenser? well worth the 12 odd dollars it costs.

Cazza Posted January 22, 2012 Author Share Posted January 22, 2012 yes have replaced the condenser and have set everything according to factory settings. no dice. Quote Link to comment Share on other sites More sharing options...
Unclejake Posted January 22, 2012 Share Posted January 22, 2012 The carb seems likely. Perhaps the accelerator pump diaphragm is split. Quote Link to comment Share on other sites More sharing options...
Duddley Posted January 22, 2012 Share Posted January 22, 2012 carb all seems to be working fine. will check the diaphragm though. Quote Link to comment Share on other sites More sharing options...

two_days_late Posted January 22, 2012 Share Posted January 22, 2012 If it is the carby, I have a 32/36 Weber on the manifold for sale. Just pulled it off the engine working fine. You're welcome to try it out and see if that's the prob if you can get someone to take it up from Welly. Quote Link to comment Share on other sites More sharing options...
Cazza Posted January 22, 2012 Author Share Posted January 22, 2012 how much are you after for it? im sure i can find someone to bring it up for me the current carb seems to be working fine but screw it- ive replaced everything else i can think of...whats one more aye. lol Quote Link to comment Share on other sites More sharing options...
dominic Posted January 23, 2012 Share Posted January 23, 2012 I would check that your venturi's are not loose and able to rattle, I recall that this can sometimes cause the described problem Quote Link to comment Share on other sites More sharing options...
two_days_late Posted January 23, 2012 Share Posted January 23, 2012 There's one on TradeMe for $300 but that seems pretty excessive. How about $100 with the manifold if you can find someone to take it up for you and if its not the carby just send it back down? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted January 23, 2012 Share Posted January 23, 2012 Giz carby to me - I will give to Seedy/Lee/Simon next week at Wagnats and they can deliver it all together personally with a smile and no pants. Quote Link to comment Share on other sites More sharing options...
Cazza Posted January 23, 2012 Author Share Posted January 23, 2012 As tempting as that prospect is (and no i dont think Duddley would get ever so slightly jealous at all...)...no thanks! haha Will decline offer of carb for now with thanks- have found one amongst our spares so will give that a whirl first....

Horse25 Posted January 25, 2012 Share Posted January 25, 2012 Just out of interest what things did you fix? Quote Link to comment Share on other sites More sharing options...
Cazza Posted January 26, 2012 Author Share Posted January 26, 2012 found a missing sur-clip on carb, then found split in fuel line, adjusted tappets AGAIN (they keep shifting themselves), changed timing AGAIN (to compensate for happier engine), ... oh and please see "Parts for Sale" section. I need a new brake master cylinder. mine wont quit with the leaking despite having new seal set put in it. ah i love ongoing projects....
