fantic 300 pro Posted September 2, 2014 Report Share Posted September 2, 2014 My 350T was recently fitted with new points and condenser. After letting it sit for about a month it will no longer start. I have ruled out any issues with the carb. The bike has a big fat blue spark. Could the ignition timing be out?

b40rt Posted September 2, 2014 Report Share Posted September 2, 2014 Have you tried petrol directly into the cylinder ? Quote Link to comment Share on other sites More sharing options...
fantic 300 pro Posted September 2, 2014 Author Report Share Posted September 2, 2014 No I haven't tried pouring a little petrol directly in the cylinder. I have tried squirting a little starting fluid in their. No joy whatsoever. Should I try a petrol/oil mix directly in the cylinder? Quote Link to comment Share on other sites More sharing options...
b40rt Posted September 2, 2014 Report Share Posted September 2, 2014 Worth a try, also a new plug. Quote Link to comment Share on other sites More sharing options...
lineaway Posted September 3, 2014 Report Share Posted September 3, 2014 Is the plug wet or dry? Quote Link to comment Share on other sites More sharing options...
bullylover Posted September 3, 2014 Report Share Posted September 3, 2014 If you have installed new points and condenser you will have to retime the ignition. Even changing the points gap will change the timing. So reset the points to 15 thou or .40mm and then time the ignition to 2.6 mm BTDC ( this is the factory recommendation) I like them at 2.9 mm BTDC which gives them a little bit more zing. 2 Quote Link to comment Share on other sites More sharing options...
fantic 300 pro Posted September 4, 2014 Author Report Share Posted September 4, 2014 I have put three new plugs in it and they are all wet after I try starting it. I am thinking the ignition timing needs setting properly. Quote Link to comment Share on other sites More sharing options...
bullylover Posted September 5, 2014 Report Share Posted September 5, 2014 Have you checked the flywheel key? It may have sheared. 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted September 6, 2014 Report Share Posted September 6, 2014 Sounds to me like the lower end is just flooded. One kick and it wets the plug. Pull the plug and maybe the head pipe too! You can kick it through without the plug. Be careful of a fire. Been more than one bike I`ve seen go up in flames. Quote Link to comment Share on other sites More sharing options...
fantic 300 pro Posted September 7, 2014 Author Report Share Posted September 7, 2014 False alarm on this one.... After spending three prior attempts to get it running I tried again today and it started first kick LOL! Now all I need to do is figure the jetting out as it unresponsive and has very little power. If you fellas have any thoughts/ideas on a fix I would be very greatful. Thanks to all of you for your help and advice. Quote Link to comment Share on other sites More sharing options...
pschrauber Posted September 7, 2014 Report Share Posted September 7, 2014 (edited) If you have a Dellorto PHBH 28 BS mounted: - main: 110 - needle: X2, second notch from top - needle jet: AV 264 - idle jet: 55 - idle screw: depending your location around 1,75 turns 28mm is right (sorry) Edited September 7, 2014 by pschrauber Quote Link to comment Share on other sites More sharing options...
fantic 300 pro Posted September 7, 2014 Author Report Share Posted September 7, 2014 My bike has a Dellorto PHBH 28 BS mounted to it. It is in very good/clean condition. I have stripped and cleaned it on three separate occasions. - main: 110 (I think my main is a 115 though this is hard to tell as the marking is worn) - needle: X2, second notch from top (correct needle) - needle jet: AV 264 (needle jet is a AV 264 - I believe the 28MM carb should have a AV 266 needle jet) - idle jet: 55 (I think my idle jet is a 58 but it's hared to be sure as the marking is worn) - idle screw: depending your location around 1,75 turns (correct) Bike has a 60 slide fitted Brand new 200 needle valve and seat fitted as the old seat was badly worn Quote Link to comment Share on other sites More sharing options...
pschrauber Posted September 7, 2014 Report Share Posted September 7, 2014 Yep sorry the 350 cc has a 28mm in diameter, (the 250cc model has a 26mm) ... I mixed up the rows while writing off the spec's the other values depending the jets .. are right the post is already edited. Quote Link to comment Share on other sites More sharing options...
lbhbul Posted September 18, 2014 Report Share Posted September 18, 2014 Only my thoughts; Spark on the outside can be misleading compared to firing under compression. in my experience with points ignition and what you describe, try adding an automotive condenser under the tank, quick & cheap try. I take it was running after the new points & condenser ? Larry Quote Link to comment Share on other sites More sharing options...
lbhbul Posted September 21, 2014 Report Share Posted September 21, 2014 Fantic 300, Is it running? Thanks, Larry Quote Link to comment Share on other sites More sharing options...
