treehopper Posted October 27, 2010 Share Posted October 27, 2010 Can anyone help........... My 1100as has become more and more reluctant to start on the button, and finally whilst in Spain it let me down all together yet one pull on the cord and away it goes The starter and ignition system are totally seperate so the starter is not drawing all the power. The coil was changed some time ago......... any ideas????? Quote Link to comment Share on other sites More sharing options...

De compressor blocked? but would be difficult on the hand start if this was the case Quote Link to comment Share on other sites More sharing options...
weesplat Posted October 28, 2010 Share Posted October 28, 2010 Hi Jamie, Think cobra has a point with the de-compresser being blocked. It would slow the swing using the starter as the light weight batterys used have limited power. On the pull start you give it more oomfhh. Worth a look anyway.

outkast Posted October 28, 2010 Share Posted October 28, 2010 Hi jamie, you may find a new battery will help, the motorcycle battery that was on it was the second one I fitted, try jump starting it off another battery, if all is fine then I would look to changing the battery, I was never able to start it by hand, I did take the head off and check the decompresser but that was fine, but may need checking again as that was over a year ago. cheers, Dave Quote Link to comment Share on other sites More sharing options...
pete_b Posted October 28, 2010 Share Posted October 28, 2010 The electric start system is totally separate to the ignition and turns the engine over fast but it will not fire up. If you pull it over by hand it will start no problem (even though it is turning over A LOT slower. Got me puzzled at the moment Quote Link to comment Share on other sites More sharing options...

Got me puzzled at the moment so the battery is turning it over ok? but it will start while being cranked slower? hhhhmmmmm got me stumped too Quote Link to comment Share on other sites More sharing options...
cobra Posted October 28, 2010 Share Posted October 28, 2010 Hmm, all i can think of is, because it is turning over slower, it is seeing the flywheel magnets over the mag for longer generating a bigger spark? i suppose it has been checked for spark with the plug in and the lead took to a spare plug earthed and also with the plug out of the cylinder to get a comparrison check on starter motor then the same by hand start? once it has started it runs, but struggles to start when turning over fast. it could need the mag re adjusting with the paper card as a feeler guage if 1 is not available. timing slipped? woodruff key worn allowing movement of the flywheel? starter causing a ground loop to earth thus earthing the coil along the way on start up, this will be noted on the spark test. lastly carb, but that seems a long shot at the mo btw are the rings ok on the piston? not stuck in by any chance?? you will be able to tell through the exhaust port Quote Link to comment Share on other sites More sharing options...
edwardc Posted October 28, 2010 Share Posted October 28, 2010 I agree with Dave with the place to start. I have had cars that turned over ok but the starter drains a lot of power from the battery so they would start on a push. Try another battery and if that doesn't work have the starter motor checked. Lets keep this simple to start with! Eddie Quote Link to comment Share on other sites More sharing options...

Eddie re read the post and phil b above. magnetos do not require a battery within the ignition circuit, low tension is generated via some electronics within the mag and then HT is generated again within the mag then to the plug. the battery is just for the starter motor 1 other thing i forgot, check the mags earth Quote Link to comment Share on other sites More sharing options...
dantheman Posted October 28, 2010 Share Posted October 28, 2010 Do you have the battery on constant trickle charge when not in use, or do you give it an hours top up on the way to the flying field ? if the latter then I'd suggest a battery optimiser to make sure it's always tip top.

bendmeroundthehedge Posted October 29, 2010 Share Posted October 29, 2010 Try and simulate the pull start action by popping the starter instead of holding it on. Quote Link to comment Share on other sites More sharing options...
garyfreefly Posted October 29, 2010 Share Posted October 29, 2010 bendmeroundthehedge I like it thinking outside the box heres another outside the box solution Get rid of the battery and starter and just pull the ruddy thing I seem to cope without a electric starter and think of all that lovely lost weight...... ps it also reduces the chance of FIRE ( Yes it did happen to me at 1000ft )due to all those electrics going wrong thats why I wont even consider an electrical start anymore Quote Link to comment Share on other sites More sharing options...

Even some one else pull starting it when he is standing up is very difficult. Quote Link to comment Share on other sites More sharing options...
bendmeroundthehedge Posted October 29, 2010 Share Posted October 29, 2010 Hi Pete, Have you tried jump leads diectly onto the starter? Will it start then? Also, is there a spark when cranking with the starter button? Kev Quote Link to comment Share on other sites More sharing options...

Jamie try the spark pulling it and spinning it on the starter and report back please. Quote Link to comment Share on other sites More sharing options...
treehopper Posted October 29, 2010 Author Share Posted October 29, 2010 Thanks to you all for your sugestions looks like ive got a busy day in the workshop tomorrow will report back with results. Quote Link to comment Share on other sites More sharing options...
treehopper Posted October 30, 2010 Author Share Posted October 30, 2010 Well ive had that day in the workshop! and there's a lot to be said about starting with the easy stuff first. Battery was fully charged before going to Spain (so i thought) and, as everyone who was there will say, it was cranking very well, Simon actually said "sling the motor and fly using the battery". It would appear that i was getting a false reading from the battery charger, having used a different charger it has gone from cranking at warp factor 10 to warp factor 20 and starts no problem. but why it started so easy on the cord is still a mystery as the starter was still cranking it faster than you could ever pull start it !!! Many thanks for all your ideas Quote Link to comment Share on other sites More sharing options...
