hi all,,,I'm kinda new to the whole mechanical side of things. i bought a ke70 with a blown head gasket about a week ago so far

ive done the head gasket and put it all back together and i also replaced the fuel pump

 

when i turn the key it turns over sounds healthy but it just dosnt want to start

 

i checked for spark and the timing and they seem fine,,,when turning over the carby puffs,,,and the battery starts to die I'm guessing this is normal? but it just dosnt want to start

 

has this happend to anyone else before? any advice would be really helpful

 

cheers luke

There re only three thngs involved-

 

Fuel, electricity and coordination!

 

Fuel- no leaks in the inlet system? Carb pumps fuel down the throat OK? Does the engine fire or cough or backfire?? The choke works correctly??

 

Electricity- Have you seen a spark at the end of a spark plug?? Are you absolutley sure you know which way the dizzy turns, that you have the right points gap and that it fires at 8deg BTDC.

 

Coordination- Did you touch the cam setup at all? or just head off and on. Are the tappets set to the right gap. If you don't coordinate fuel and electricity it won't start!

 

I'd bet ignition myself, it seems to trip up a lot of people.

make sure that the dizzy isnt 180degrees out its an easy thing to get wrong

 

 

ive checked the plugs ther all ok,,,and the fuel does get in there,,,how do i check the dizzy and yes it was just the head off and on and the tappets are set proper

Tappet cover off

 

Turn motor by hand until the timing mark comes around AND number 4 cyl has the exhaust valve closing. That makes sure number 1 is on firing stroke.

 

Turn on ignition, take off dizzy cap.

 

Watch the rotor as you turn the last 20deg, the points rubbing block will be approaching one of the 4 shoulders of the rotor's center cam, and the points should spark as they open as the crank shows 8deg timing BTDC. Make sure the rotor points to number one plug lead.

got it going cheers for your help guys :D

What was the problem?
