please somebody help,my biz wont start ive renewed the plugs,ht leads,points,condensor,fuel pump,cleaned the carb and yet still no heart beat.what am i doing wrong help.......
-
is it turning over or dead?
Is there fuel?
Spark?
-
Did you change the pump main rod??
Do check that carb is getting fuel and take off dizzy cap and check for spark by inserting a skrewdriver between contact points with ignition on. Also make sure you got the petrol pipes fitted the right way on the pump. Keep us posted cheers Peter.
-
thanks for reply,yes i have spark to points fuel to carb but still no life
every time i try to start her she keeps back firing so im not far off
Thanks.....

Sounds to me as if you haven't got the ignition timing set correctly, If you have had the distributor out it need to go back in the same position, Did you check the static timing once you had reset the points ???
-
cheers for that ,the guy i bought it of has told me
he took it off to clean it .so i think you guys are right
now the thing is setting ignition timing anybody help
thanks in advance

Ive recently had similar problems, if yours has a waster spark coil, take both spark plugs out and attach the HT leads to them, sit the plugs on the exhaust or something that will give a good earth. (they both need to be earthed)
then with the dizzy cap off and with the engine in a position so as the points are closed, ignition on, flick the pints open by hand and watch that both plugs spark together. flick it a number of times to be sure that on every occasion they both give a strong simultaneous spark if they dont try them in different positions, swap leads, if the same plug plays up renew it.
ive never done the timing on a bis, but the manuals describe it simply enough. on the air cooled its easiest to remove the rocker cover, turn the engine until both valves on cylinder 1 (nearest to you) are closed (i.e spring fully released/raised) and that the two valves on cylinder 2 are level. the notch on the crank pully should be in line with the timing marks. Line the notch up with the marker that indicates 10 degrees before tdc. then release the dizzy clamp nut so that you can turn the dizzy, twist the dizzy so that the points are just about to open and job done.
check that the rocker cover isnt cranked down so hard that its holding the rockers down.

Or if you have access to a strobe light connect it between the plug lead and the plug, disconnect the vacuum advance pipe from the distributor, then get someone to crank the engine on the key while you adjust the distributor until the notch on the pulley aligns with the 10 deg mark on the block when the light flashes.
P.S. if you need to pick-up a live feed for the strobe you can connect the + to the large post on the back of the starter motor. - down to the body or engine block [-/

Thanks for the info chaps,good news shes up and running,yes it was the timing......a mile out

Good News! Did you here the fan cutting in ??? And keep an eye on the temp gauge :)
-
Cheers for that Pete
