Hi can anyone help? My project 88 xr3i was a perfect runner been in garage for approx 6 months, along with doing bodywork i decided to replace battery and run for a while. The car started perfect and then it seemed like when the choke shut off the engine spluttered and stopped now it just wont start. any pointers appreciated

 

possibly try some fresh fuel and new fuel filter mate, as been sat for a while even do service plugs, filters mite do the trick!

 

Cheers will try that, i just want to add that on occasions when turning over the engine back fires like the timings out or something is there any sensors or something that may fail.

 

as said above mate probably stale fuel happens to my bike when its put away for the winter,normally try to frain the tank when i put it away now.Would definatly try that first.

 

not too sure of that mate but ive just had the same sort of thing with a 306 not sure if moisture got into the exhaust of fuel laying in it but that was like you said backfiring but once got it started was like the exhaust was blocked when i tried to rev it up, so left it to idle for about 20 mins and cleared itself out!

 

check the flap on the K-Jet metering head isnt seized, just stick your hand in and check it goes up and down.

on my old XR4i the metering heag got stuck once, it must have gone a bit manky. some WD40 and a few good pushes up and down cleared it
