18R-C starting woes (need 18r guru)

[mikie]

Hey I just swapped over motors in my ra40, 18r-c to 18r-c and it has been running fine til this morning where it wouldn’t start, it has fuel and spark, both checked, it cranks fine but just won’t kick over. The motor it has now is from a ra23 since it’s the only motor I could get a hold of at short notice. Anyone got any ideas???

Help needed quick

Cheers Mike

fuel pump?
plug leads?

try to do a long roll-start

[mikie]

the fuel pump seems fine coz it sprays into the carby and the filter and float tank are full, as well as the leads, pulled each spark plug out and the checked for spark, all came up fine.
ill try a roll start when i get home.

Check electrical leads aswell.... the coil mainly
carby possibly

when my 18r had problems it was the electrical wires touchin earth

regards kenno

all good now. the gap on the rotor button was to large due to ware. seems that the spark from the coil was to weak to ignite the mix, replaced rotor button and all is good.

+rep for everyone that helped
